Summary of the invention

The embodiment of the invention provides a kind of method for handling message and equipment is calculated, when can reduce the processing of message Prolong, improves the processing capacity for calculating equipment.

In order to achieve the above object, the present invention adopts the following technical scheme:

In a first aspect, providing a kind of method for handling message, this method is applied to calculate in equipment, and the calculating equipment is pre- First Business Stream is established with opposite end calculating equipment to connect；This method comprises:

The message connected from the Business Stream is received, the serial number carried in the message and payload data are obtained；

It is determined to connect in corresponding receiving queue in the Business Stream according to the serial number of the message and stores the payload number According to deviation post；

The payload data is stored into the receiving queue based on the deviation post.

Specifically, receiving end calculate equipment network interface card receive from Business Stream connection TCP message, complete link layer, Network layer, the protocol processes of transport layer, obtain TCP serial number and payload data entrained by the TCP message, and payload data is institute State the content-data in TCP message.

By foregoing description process, when receiving message, can be directly determined according to the TCP serial number of message in the reception The deviation post of the payload data of the message is stored in queue, and is directly stored the payload data empty to corresponding storage Between.In this way, additional reassembly buffer area is not needed in message processing method provided in an embodiment of the present invention, not first in weight yet The multiple messages received are ranked up in group buffer area and then in order read the payload data of the message after sequence The process of receiving queue, but directly arrived the payload data storage of the message according to the serial number of the message after receiving message In receiving queue, the processing delay of message is thus significantly reduced, improves the process performance for calculating equipment.

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiment is a part of the embodiments of the present invention, rather than whole embodiments.Based on this hair Embodiment in bright, those of ordinary skill in the art's every other reality obtained without making creative work Example is applied, all should belong to the scope of protection of the invention.

The present invention is suitable for different calculating equipment and is based on transmission control protocol/Internet Protocol (Transmission Control Protocol/Internet Protocol, TCP/IP) scene that carries out data transmission, Fig. 1 is the meter of receiving end The schematic diagram of equipment is calculated, as shown, calculating equipment includes that application software, operating system, CPU, memory, network interface card and network interface card drive It is dynamic, wherein network interface card, which can be, unloads engine (TCP Offload Engine, TOE) network interface card comprising TCP；The receiving end calculates Equipment can receive transmitting terminal and calculate the message that equipment is sent by network.The calculating equipment can be server or other realities Body.

Receiving end calculating equipment pre-establishes a Business Stream with transmitting terminal calculating equipment and connects, and such as TCP connection is described TCP connection has contextual information, which is used to record the parameter and state of the TCP connection, wherein including with institute State the contextual information of the corresponding receiving queue of TCP connection (Receive Queue, RQ), the receiving queue for manage with The corresponding memory space for receiving buffer area of the receiving queue.

It will be understood by those skilled in the art that transmitting terminal calculates equipment meeting basis and connects in TCP message transmission process Receiving end calculates the result that equipment is negotiated and data to be sent is cut into several data segments, and using the data of each data segment as Payload data is encapsulated as a TCP message and is then sent to the receiving end calculating equipment.The length of each data segment is by receiving End calculates equipment and transmitting terminal calculates the result that equipment is negotiated and determines, may be the same or different, therefore receiving end calculates and sets It is standby to receive the message comprising same size or different size of payload data.The embodiment of the present invention in detail below In description, is calculated for equipment receives several messages of isometric size and be described in detail by receiving end.

Wherein, each TCP message includes TCP stem and payload data two parts, and TCP stem includes serial number again, the sequence Number for identify from transmitting terminal calculate equipment to receiving end calculate equipment send data word throttling, i.e., serial number expression transmitting terminal meter Calculate byte count value of first data byte in entire data flow to be sent in each data segment transmitted by equipment.Example Ground, it is assumed that transmitting terminal is calculated equipment and is segmented data flow to be sent as unit of 1000 bytes, every one piece of data carrying It is sent to receiving end in 1 TCP message and calculates equipment, then the serial number 0 of first message, the serial number of second message are 1000, the serial number of third message is 2000 ..., and so on.

After the completion of the TCP connection of Business Stream is established, receiving end calculates equipment can receive the message of each segmentation successively, this Field technical staff causes receiving end to calculate equipment and receives message it is to be understood that due to Network Packet Loss, time delay etc. It is different that the sequence of the message is sequentially sent from transmitting terminal calculating equipment, that is, there are problems that " random ordering ".As shown in Fig. 2, being this hair A kind of message processing method that bright embodiment provides is receiving random ordering for solving receiving end calculating equipment in the prior art Message post-processes the problem of time delay is longer and finally influence calculates equipment disposal ability.This method comprises:

The message that S201, reception are connected from Business Stream, obtains the serial number carried in the message and payload data.

S202, according to the serial number of the message determine the Business Stream connect stored in corresponding receiving queue it is described net The deviation post of lotus data.

S203, the payload data is stored into the receiving queue based on the deviation post.

Wherein, receiving queue can be by least one the buffer descriptor container (Buffer of chain together Descriptor Container, BDC) composition, each buffer descriptor container is by least one buffer descriptor (Buffer Descriptor, BD) and 1 connection buffer descriptor (Linking Buffer Descriptor, LBD) Composition, each buffer descriptor receive corresponding a part of memory space in buffer area for managing；The connection is slow Area's descriptor is rushed for being directed toward next buffer descriptor container in the receiving queue.

Deviation post, which is used to indicate, to be held in the receiving queue for storing the buffer descriptor of the payload data Buffer descriptor in device.It can be determined according to the TCP serial number determined in step S201 and be used in the receiving queue In the deviation post for storing the payload data, it that is to say and determined in the receiving queue with being included in which BDC The memory space which BD is managed stores the payload data.

Illustratively, Fig. 2A is the schematic diagram of message processing method, as shown, buffering of the receiving queue 1 by chain together Area's descriptor container 1 and buffer descriptor container 2 form, and each buffer descriptor container includes 3 buffer descriptors, Each buffer descriptor management receives the memory space that 4KB is corresponded in buffer area；Assuming that the payload data of each message is 4KB can then use n, n+4K, n+8K, n+12K, n+16K, n+20K ... successively as the TCP serial number of each message respectively；Its In, it is assumed that the message of TCP serial number n is that data to be sent are cut into the first section data in several data segments as payload data A message being packaged into；T1 moment, T2 moment, T3 moment, T4 moment, T5 moment and T6 moment respectively indicate receiving end calculating At the time of equipment receives message, wherein T1 to T6 is 6 moment sorted in chronological order；The T1 moment receives TCP serial number n Message, obtain the payload data of the message, according to TCP serial number can be confirmed its deviation post be buffer descriptor container Payload data in the message is then stored in the reception that buffer descriptor 11 is managed and buffered by buffer descriptor 11 in 1 Memory space corresponding to area；The T2 moment receives and takes TCP serial number n+4K, can determine that deviation post is answered according to TCP serial number For buffer descriptor 12 in buffer descriptor container 1, then the packet storage is managed in buffer descriptor 12 Receive memory space corresponding to buffer area；The T3 moment receives the message of TCP serial number n+12K, according to its TCP serial number n+ 12K can determine that its deviation post is buffer descriptor 21 in buffer descriptor container 2, then by the payload in the message Memory space corresponding to the reception buffer area that data storage is managed to buffer descriptor 21；The T4 moment receives TCP sequence Number be n+16K message, according to TCP serial number n+16K can determine its deviation post be buffer descriptor container 2 in buffer area Descriptor 22 then stores the payload data in the message corresponding to the reception buffer area managed to buffer descriptor 22 Memory space；Similarly, T5 moment and T6 moment receive the message of TCP serial number n+8K and n+20K respectively, then according to it TCP serial number is respectively stored into corresponding to the reception buffer area that buffer descriptor 13 in buffer descriptor container 1 is managed Memory space corresponding to the reception buffer area that buffer descriptor 23 is managed in memory space, buffer descriptor container 2. In conjunction with above-mentioned example, receiving end calculates equipment after receiving message, directly will be in the message according to the TCP serial number of message The corresponding memory space in reception buffer area that is managed to receiving queue of payload data storage in, this completes report to random ordering The sequence of text.

By foregoing description process, buffer area is received using buffer descriptor Container Management in receiving queue, works as reception When to message, determined according to the TCP serial number of message slow in the buffer descriptor container for storing the payload data of the message Area's descriptor is rushed, and the payload data is stored to corresponding memory space.In this way, at message provided in an embodiment of the present invention In reason method, out-of-order Packet reassembling can be completed according to TCP serial number directly in receiving queue, do not need as the prior art that Sample separately divides reassembly buffer area, is not also first ranked up then the multiple messages received by suitable in reassembly buffer area The payload data of message after sequence is read the process of receiving queue by sequence, thus reduces the processing delay of message, and mention The process performance for calculating equipment is risen.

In the above-described embodiments, it is connected for each Business Stream and pre-generates 1 corresponding receiving queue, it is described to connect It is consistent with the receiving window size that receiving end calculates equipment and transmitting terminal calculating equipment negotiation to receive queue.The receiving queue is managed The storage resource that the memory space of the reception buffer area of reason is managed from reception buffer resource pond, in specific implementation process In, even if the connection of sluggish Business Stream is also required to distribution receiving queue corresponding with window is received, but actually these are received The reception buffer area that queue is managed is possible without to be used immediately, be easy to cause the wasting of resources in this way.Therefore, the present invention is real Example is applied to advanced optimize as using shared receiving queue (Shared Receive Queue, SRQ) mechanism, i.e., a plurality of Business Stream connects Corresponding receiving queue is connect to be associated in shared receiving queue with the shared storage resource for receiving buffer resource pond.

Optionally, for method described in step S201 to step S203, step S201 especially in the method is operated Before, the method also includes:

At least one can be pre-created in receiving buffer resource pond and share receiving queue (Shared Receive Queue, SRQ), each shared receiving queue includes multiple buffering area descriptor container.

Specifically, 1 shared receiving queue can be pre-created in the trawl performance for calculating equipment, share receiving queue by chain At least one buffer descriptor container composition together, each buffer descriptor container includes the buffer area of same number Descriptor, and in the shared message queue, each buffer descriptor management receives in buffer area and corresponds to memory space Size is identical.

Then receiving end calculates equipment when establishing Business Stream connection, and the receiving queue that the Business Stream connects is corresponded to institute The shared receiving queue stated can be by the predefined quantity in the shared receiving queue when receiving queue initializes Buffer descriptor container is mounted in the receiving queue.

Further, with the message for calculating equipment from transmitting terminal is constantly received, these messages are stored in described In receiving queue, then when judging that the buffer descriptor container use ratio in the receiving queue reaches predefined first threshold When, can again by least one buffer descriptor container in the shared receiving queue be mounted in the receiving queue so as to Store the payload data of the subsequent message that will be received.

Illustratively, as shown in Figure 3, it is assumed that predefined first threshold is 50%, when buffer descriptor holds in receiving queue Corresponding storage in the reception buffer area that buffer descriptor 11, buffer descriptor 12, buffer descriptor 13 are managed in device 1 After space is all filled up by payload data, then buffer descriptor in the corresponding shared receiving queue 100 of the receiving queue is held Device 11 is mounted on the buffer descriptor container chain of receiving queue 1, and the connection buffer area of buffer descriptor container 2 is retouched State the buffer descriptor 111 that symbol is directed toward in the buffer descriptor container 11.

Optionally, if according to receiving end calculate equipment network interface card institute received message TCP serial number confirm receiving queue in when Preceding available buffer descriptor container can not save the payload data of the message, then by the shared receiving queue extremely Few 1 buffer descriptor container carry is in the receiving queue.

Illustratively, confirm that there is no confirm according to the TCP serial number in receiving queue by receiving the TCP serial number of message When deviation post, at least one available buffer descriptor container to shared receiving queue application is needed to be mounted to the reception In queue, to store the payload data of the message.As included 2 buffer descriptor containers, Mei Gehuan in receiving queue Rushing area's descriptor container includes 3 buffer descriptors, and each buffer descriptor management receives in buffer area and corresponds to depositing for 4KB Space is stored up, then receiving queue management receives the memory space that 24KB is corresponded in buffer area, it is assumed that the message of TCP serial number n is original The first section message for sending data is originated, when receiving end, which calculates equipment, receives the message of TCP serial number n+40K, nothing in receiving queue Method stores the payload data of the message, then needs to hang to shared receiving queue application 2 available buffer descriptor containers It is downloaded on the buffer descriptor container chain of receiving queue 1, the payload data in message to store TCP serial number n+40K.

As multiple receiving queues are constantly to shared receiving queue application buffer descriptor container, when shared receiving queue When the use ratio of middle buffer descriptor container reaches predefined thresholds, the trawl performance for calculating equipment can use reception and delay It rushes memory space idle in area resource pond and forms new buffer descriptor, be filled into new buffer descriptor container, The new buffer descriptor container of multiple new buffer descriptor recompositions, is mounted in shared receiving queue, so as to It improves the resource bid efficiency of receiving queue and calculates equipment disposal ability.

Illustratively, it when the use ratio of buffer descriptor container in shared receiving queue reaches 70%, can use Idle storage space constructs new buffer descriptor, the buffer descriptor of multiple new buffer descriptor set Cheng Xin The new buffer descriptor container is mounted in the shared receiving queue by container, so as to for receiving queue application and It uses, so as to improve business processing efficiency, reduces Message processing time delay.

Optionally, when in shared receiving queue available buffer descriptor container be unable to satisfy receiving queue required buffer When the number of area's descriptor container requires, the trawl performance for calculating equipment, which can use, receives idle in buffer resource pond deposit Storage space forms new buffer descriptor, is filled into new buffer descriptor container, multiple new buffer areas are retouched The new buffer descriptor container of symbol recomposition is stated, is mounted in shared receiving queue, to improve the resource Shen of receiving queue It please efficiency and calculating equipment disposal ability.

Illustratively, when receiving queue needs to apply 3 buffer descriptor containers, but it is available slow in shared receiving queue When rushing area's descriptor container and only having 2, trawl performance, which can use, receives memory space composition idle in buffer resource pond New buffer descriptor container, and be mounted on the chain of buffer descriptor container of the receiving queue.

Optionally, the shared receiving queue of multiple and different depth can also be created simultaneously.

Illustratively, trawl performance can also establish multiple shared receiving queues simultaneously, every in the same shared receiving queue The buffer descriptor number that a buffer descriptor container is included is identical, and each buffer area is retouched in different sharing receiving queue Stating the buffer descriptor number that symbol container is included may be the same or different.

It is worth noting that the storage size that each buffer descriptor is managed in the same shared receiving queue Identical, the storage size that buffer descriptor is managed in different sharing receiving queue may be the same or different, this Invention is with no restriction.

Illustratively, after receiving end calculating equipment and transmitting terminal calculating equipment establish TCP connection, according to the business of TCP connection The corresponding receiving queue 1 of the TCP connection is associated with by priority with shared receiving queue 100, is buffered in shared receiving queue 100 Area's descriptor container includes that 3 buffer descriptors hold, and each buffer descriptor management receives depositing for the corresponding 4KB in buffer area Store up space；When transmitting terminal calculating equipment and receiving end calculating equipment room network environment are preferable, as receiving end calculating equipment is received For message there are when less out-of-order message, it is shared connect that receiving end, which calculates the corresponding shared receiving queue of equipment adjustment receiving queue 1, Receive queue 200, wherein each buffer descriptor container includes 2 buffer descriptors in shared receiving queue 200, each Buffer descriptor management receives the memory space of the corresponding 2KB in buffer area, to achieve the purpose that service feature is optimal.

Description through the above can be reached according to the use ratio of buffer descriptor container in shared receiving queue To predefined thresholds or when being unable to satisfy the number requirement of receiving queue required buffer area descriptor container, trawl performance can benefit New buffer descriptor container is created with idle storage resource, is mounted to the buffer descriptor container of shared receiving queue On chain, time-consuming of the receiving queue to shared receiving queue application storage resource is reduced with this, improves business processing efficiency.Another party The shared receiving queue of multiple and different depth can be pre-created in face, and in conjunction with flow control algorithm, in TCP traffic stream process mistake Different business priority is set in journey, is that every TCP connection selects best match to share receiving queue according to priority, by business Performance is optimal.

In conclusion determining that the buffer descriptor for storing the payload data of the message holds according to the TCP serial number of message Buffer descriptor in device, and by payload data storage to corresponding memory space, can directly in receiving queue root Out-of-order Packet reassembling is completed according to TCP serial number, compared with prior art, does not need separately to divide reassembly buffer area, also without first The multiple messages received are ranked up in reassembly buffer area and then in order read the payload data of the message after sequence The process for getting receiving queue thus reduces the processing delay of message, and improves the process performance for calculating equipment.Another party Face, by sharing receiving queue mechanism, the TCP connection of a plurality of Business Stream is shared to receive buffer resource pond, solves existing skill Because the TCP connection of sluggish Business Stream is also required to distribution and the corresponding reception buffer area of reception window in art, actually this A little buffer areas are possible without to be used immediately, is led to the problem that resource utilization is low, is improved and receive buffer resource pond Resource utilization.And when storage resource is insufficient in receiving queue or judges that the buffer descriptor container in receiving queue uses When ratio reaches predefined first threshold, by least one buffer descriptor container carry in shared receiving queue described In receiving queue, on the other hand, when network flow moment leap high or Network Packet Loss serious conditions under, can be to shared reception The available buffer descriptor container of queue application improves traffic handing capacity, reduces processing delay.It can also be calculated with flow control Method combines, and different business priority is arranged during TCP traffic stream process, is that every TCP connection selects most according to priority It is good to match shared receiving queue, service feature is optimal.

In another possible embodiment of the invention, when the network interface card for calculating equipment completes link layer, network layer, transport After layer protocol processing task, calculating equipment can read payload data, to complete the processing of application layer.Receive buffer resource with Buffer descriptor is unit release, which comprises

If any buffer descriptor is managed on the chain for the buffer descriptor container that the receiving queue is managed The corresponding memory space in reception buffer area complete payload data filling, and in any buffer descriptor to the reception The reception buffer area that all buffer descriptors of the first-in-chain(FIC) for the buffer descriptor container that queue is managed are managed is corresponding Payload data filling, and connecing of being managed of the buffer descriptor before any buffer descriptor is completed in memory space The payload data received in the corresponding memory space in buffer area is read by the calculating equipment, then described in the calculating equipment reading The payload data stored in the corresponding memory space in reception buffer area that any buffer descriptor is managed.

Illustratively, Message processing flow diagram as shown in Figure 2 A, at the T1 moment, what buffer descriptor 11 was managed deposits It stores up space to be filled by the payload data in the message of TCP serial number n, buffer descriptor 11 is the buffering of first-in-chain(FIC) in receiving queue Area's descriptor, then after receiving end calculates the equipment reading payload data, the reception that release buffer descriptor 11 is managed is slow Rush the corresponding memory space in area；At the T2 moment, the corresponding memory space in reception buffer area that buffer descriptor 12 is managed is by TCP Payload data in the message of serial number n+4K fills up, and on the buffer descriptor container chain of receiving queue, buffer area is retouched The payload data in the corresponding memory space in reception buffer area that buffer descriptor 11 before stating symbol 12 is managed is read It takes, then receiving end calculates equipment and reads the payload data, and discharges the reception buffer area pair that buffer descriptor 12 is managed The memory space answered；At the T3 moment, the memory space that buffer descriptor 21 is managed is by the message of TCP serial number n+12K Payload data filling, but at this point, buffering on the buffer descriptor container chain of receiving queue, before buffer descriptor 21 The corresponding memory space in reception buffer area that area's descriptor 13 is managed is not filled up by payload data also, then is not dealt with；When T4 It carves, the memory space that buffer descriptor 22 is managed is filled up by the payload data in the message of TCP serial number n+16K, but this When, on the buffer descriptor container chain of receiving queue, the buffer descriptor 13 before buffer descriptor 22 is managed The corresponding memory space in reception buffer area do not filled up by payload data, the reception buffer area pair that buffer descriptor 21 is managed Though the memory space answered is filled up by payload data, receiving end calculates the reception that the unread buffer descriptor 21 of equipment is managed Payload data in the corresponding memory space in buffer area, then do not deal with；T5 moment, the storage that buffer descriptor 13 is managed Space is filled up by the payload data in the message of TCP serial number n+8K, at this point, all buffer areas before buffer descriptor 13 The memory space that descriptor is managed has been filled with payload data, and receiving end has calculated equipment reading to the payload data, Then receiving end calculates the payload data in the memory space that equipment reading buffer descriptor 13 is managed, and discharges buffer area and retouch State the corresponding memory space in reception buffer area that symbol 13 is managed；T6 moment, the memory space that buffer descriptor 23 is managed It is filled up by the payload data of TCP serial number n+20K, at this point, delaying on the buffer descriptor container chain that receiving queue is managed The storage corresponding with the reception buffer area that buffer descriptor 22 is managed of buffer descriptor 21 before rushing area's descriptor 23 Space is filled up respectively by payload data but non-receiving end calculates equipment and reads, and buffer descriptor 11, buffer descriptor 12, receiving end calculates equipment reading to the payload data in the corresponding memory space of buffer descriptor 13, then receiving end calculates Equipment reads the reception buffer area pair that buffer descriptor 21, buffer descriptor 22 and buffer descriptor 23 are managed respectively The payload data stored in the memory space answered, and discharge buffer descriptor 21, buffer descriptor 22 and buffer description Memory space corresponding to symbol 23.At this point, the reception that all buffer descriptors are managed in entire buffer descriptor container 1 Corresponding memory space is released in buffer area, and buffer descriptor container 1 is invalid buffer descriptor container.Network interface card drives It is dynamic to refill buffer descriptor container using idle storage space in buffer resource pond is received, it completes after filling again It is mounted on the chain of shared receiving queue, for receiving queue application and use.

It is worth noting that the reception buffer area that buffer descriptor is managed corresponds to the release process in space, it is specific real Shi Shi, can be according to the predefined period, on the buffer descriptor container chain that receiving queue is managed, from first-in-chain(FIC) to last-of-chain Each buffer descriptor is detected one by one, when the corresponding memory space quilt in reception buffer area that any buffer descriptor is managed Payload data fills up, and all buffer descriptors before any buffer descriptor described in receiving queue are managed When the memory space for receiving buffer area is filled and receiving end calculates equipment reading, that is, discharge any reception The reception buffer area that all buffer descriptors before buffer descriptor and any reception buffer descriptor are managed Memory space.

It should also be noted that, the corresponding memory space in reception buffer area that equipment release receiving queue is managed is calculated, Specially trawl performance is discharged as unit of buffer descriptor receives buffer area, and discharges the processing for receiving buffer controlling power Process has differences in different operating system, for example, trawl performance transfers buffer controlling in Windows operating system It weighs to the operating system protocol stack for calculating equipment, and constructs new buffer descriptor with idle memory space and delay with new Rush area's descriptor container.And in (SuSE) Linux OS, after trawl performance transfers buffer controlling power, CPU will not be again by control It returns, but release is responsible for by operating system after use, need to apply again that new buffer area is associated with corresponding buffering In area's descriptor.

In conclusion receiving queue is using buffer descriptor container as administrative unit, it is possible to reduce calculate equipment CPU and providing Consumption in source control is directly completed to receive message sequence in receiving buffer queue, can solve out-of-order in the prior art Message sequence bring delay problem, reduces Message processing time delay, improves the processing capacity for calculating equipment.On the other hand, By creating the shared receiving queue of multiple and different depth, in conjunction with flow control algorithm, in conjunction with business processing priority, Network status Etc. factors, dynamic adjust the associated shared receiving queue of receiving queue, for each TCP connection select best match shared reception Queue is optimal service feature.

In alternatively possible embodiment of the invention, in conjunction with the method that step S201 is described to step S203, receive Queue can also include at least one buffer descriptor, and each buffer descriptor is right in reception buffer area for managing The memory space answered.

Confirmed in the receiving queue according to the TCP serial number that network interface card receives message for storing the slow of the payload data Rush area's descriptor；The payload data is stored in again corresponding to the buffer descriptor in the buffer descriptor of the confirmation In the memory space for receiving buffer area.

Illustratively, as shown in Figure 4 A, receiving queue 2 is retouched including buffer descriptor 21, buffer descriptor 22, buffer area Symbol 23, buffer descriptor 24 are stated, each buffer descriptor management receives the memory space that 4KB is corresponded in buffer area, it is assumed that The payload data of each message is 4KB, then can use n, n+4K, n+8K, n+12K successively as the TCP sequence of each message respectively Number, it is assumed that the message of TCP serial number n is that data to be sent are cut into the first section data in several data segments as payload data A TCP message being packaged into；T1 moment, T2 moment, T3 moment, T4 moment respectively indicate four moment of time sequencing；T1 Moment receives the message of TCP serial number n, obtains TCP serial number and the payload data in the message, confirm it according to TCP serial number Deviation post is buffer descriptor 21, then connects what payload data in the message was stored in that buffer descriptor 21 managed Receive memory space corresponding to buffer area；The T2 moment receives the message of TCP serial number n+8K, obtains the TCP sequence in the message Number and payload data, according to TCP serial number confirm its deviation post be buffer descriptor 23, then by payload data in the message It is stored in memory space corresponding to the reception buffer area that buffer descriptor 23 is managed；The T3 moment receives TCP serial number n+ The message of 4K obtains TCP serial number and payload data in the message, confirms its deviation post for buffering according to the TCP serial number It is empty then to be stored the corresponding storage in reception buffer area managed to buffer descriptor 22 by area's descriptor 22 for the payload data Between；The T4 moment receives the message of TCP serial number n+12K, TCP serial number and the payload data in the message is obtained, according to TCP Serial number confirms that its deviation post is buffer descriptor 24, then payload data in the message is stored in buffer descriptor 24 Memory space corresponding to the reception buffer area managed.In conjunction with above-mentioned example, receiving end calculates equipment after receiving message, Payload data in the message is directly stored to the reception buffer area pair managed to receiving queue according to the TCP serial number of message In the memory space answered, the sequence to out-of-order message is completed as a result,.

Optionally, be solve the TCP connection application reception buffer resource of sluggish Business Stream, but cannot immediately by The case where use, at least one shared queue can also be pre-created, each shared queue describes comprising multiple buffering area Symbol.

Then receiving end calculates equipment when establishing Business Stream connection, and the receiving queue that the Business Stream connects is corresponded to institute Shared receiving queue is stated, it, can be by the slow of the predefined quantity in the shared receiving queue when receiving queue initializes Area's descriptor container is rushed to be mounted in the receiving queue.

Further, with the message for calculating equipment from transmitting terminal is constantly received, these messages are stored in described In receiving queue, then when in the receiving queue buffer descriptor use ratio reach predefined second threshold, then to described The new buffer descriptor of receiving queue application at least one and carry are shared in the receiving queue.

Illustratively, as shown in Figure 4 B, it is assumed that predefined second threshold is 50%, is buffered included in the receiving queue 2 When the memory space corresponding with the reception buffer area that buffer descriptor 22 is managed of area's descriptor 21 is all filled up by payload data, Buffer descriptor use ratio in receiving queue reaches 50%, then retouches at least one buffer area in shared receiving queue 200 It states symbol to be mounted in receiving queue 2, and can be by 201 chain of buffer descriptor to 24 tail portion of buffer descriptor.

Optionally, if the TCP serial number according to the message confirms buffer description currently available in the receiving queue Symbol can not save the payload data, then to the new buffer descriptor of described shared receiving queue application at least one and carry In the receiving queue.

Illustratively, confirm that there is no confirm according to the TCP serial number in receiving queue by receiving the TCP serial number of message When deviation post, at least one available buffer descriptor container to shared receiving queue application is needed to be mounted to the reception In queue, to store the payload data of the message.As included 4 buffer descriptors, each buffer area in receiving queue Descriptor management receives the memory space that 4KB is corresponded in buffer area, then the reception buffer area that receiving queue currently manages is corresponding Memory space is 16KB, it is assumed that the message of TCP serial number n is to send first section message in data, when receiving TCP serial number n+ When the message of 20K, receiving queue can not save payload data entrained in the message of TCP serial number n+20K, then connect to shared 2 buffer descriptors of queue application are received, to store payload data entrained by the message of TCP serial number n+20K.

By the description of the above content, when storage resource is insufficient in receiving queue or judges buffering in the receiving queue When the use ratio of area's descriptor reaches predefined second threshold, at least one buffer area in shared receiving queue can also be retouched Symbol carry is stated on the buffer descriptor chain of the receiving queue, so as to improve business processing efficiency, when reducing processing Prolong.

In addition, receiving team when shared as multiple receiving queues are constantly to shared receiving queue application buffer descriptor The use ratio of buffer descriptor meets predefined thresholds in column, and the trawl performance for calculating equipment, which can use, receives buffer area Idle memory space forms new buffer descriptor in resource pool, is mounted in shared receiving queue, receives to improve The resource bid efficiency and calculating equipment disposal ability of queue.

Illustratively, when the use ratio of buffer descriptor in shared receiving queue reaches 70%, it can use the free time Memory space constructs new buffer descriptor, and the new buffer descriptor is mounted in the shared receiving queue, So as to for receiving queue application and use.

Optionally, delay when the quantity of available buffer descriptor in shared receiving queue is unable to satisfy needed for receiving queue When rushing area's descriptor requirement, the trawl performance for calculating equipment, which can use, receives memory space group idle in buffer resource pond The buffer descriptor of Cheng Xin is mounted in shared receiving queue, to improve the resource bid efficiency and calculating of receiving queue Equipment disposal ability.

Illustratively, when receiving queue needs to apply 3 buffer descriptors, but available buffer is retouched in shared receiving queue When stating symbol only 2 available buffer descriptors, trawl performance, which can use, receives storage idle in buffer resource pond Space forms new buffer descriptor, is mounted in shared receiving queue, is used for stored payload data.

It will be understood by those skilled in the art that receiving idle storage space in buffer resource pond can be reception buffering From the memory space being not used by area resource pond, it is also possible to the memory space discharged after receiving queue use；It is connect when shared The use ratio for receiving buffer descriptor in queue reaches predefined thresholds or is unable to satisfy the description of receiving queue required buffer area Symbol is when requiring, but when receiving in buffer resource pond without idle storage space, can not create the new buffer descriptor, can To notify administrator to carry out dilatation to the corresponding memory space in buffer area is received by alarm or event form.

Illustratively, after receiving end calculating equipment and transmitting terminal calculating equipment establish TCP connection, according to the business of TCP connection The corresponding receiving queue 2 of the TCP connection is associated with by priority with shared receiving queue 200, is shared each in receiving queue 200 Buffer descriptor management receives the memory space of the corresponding 4KB in buffer area；It is set when transmitting terminal calculates equipment with receiving end calculating Network environment is preferable between standby, and if receiving end calculates the received message of equipment there are when less out-of-order message, receiving end calculates equipment Adjusting the corresponding shared receiving queue of the receiving queue 2 is shared receiving queue 200, shares each buffering in receiving queue 200 Area's descriptor management receives the memory space of the corresponding 2KB in buffer area, to achieve the purpose that service feature is optimal.

The method described by above embodiments, receiving queue is by buffer descriptor set at equally can solve existing Reassembly buffer area leads to message data processing delay problem in technology, improves the process performance for calculating equipment.On the other hand, when sentencing Buffer descriptor container use ratio in the receiving queue of breaking reaches predefined first threshold, can also be by shared reception At least one buffer descriptor carry leaps high in network flow moment in the receiving queue or Network Packet Loss is tight in queue In weight situation, available reception buffer area can be applied for by shared receiving queue in advance, improve traffic handing capacity, reduce Processing delay.Different business priority can also be set during TCP traffic stream process in conjunction with flow control algorithm, according to Priority is that every TCP connection selects best match to share receiving queue, and service feature is optimal.In another aspect, utilizing Shared receiving queue management receives buffer resource pond, and a plurality of Business Stream is made to receive buffer area money by the way that shared receiving queue is shared Source pond, solves in the prior art that window is corresponding connects with reception because the TCP connection of sluggish Business Stream is also required to distribution Buffer area is received, actually these buffer areas are possible without is used immediately, is led to the problem that resource utilization is low, is improved and connect Receive the resource utilization in buffer resource pond.

In another possible embodiment of the invention, when the network interface card for calculating equipment completes link layer, network layer, transport After layer protocol processing task, calculating equipment can read the payload data, to complete the processing of application layer.Receive buffer area money Source is discharged as unit of buffer descriptor, which comprises
