Detailed Description

For simplicity and clarity of description, the invention will be described below by describing several representative embodiments. Not all embodiments are shown herein. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. Some embodiments are not described in detail, but rather are merely provided as frameworks, in order to avoid unnecessarily obscuring aspects of the invention. Hereinafter, "including" means "including but not limited to", "according to … …" means "at least according to … …, but not limited to … … only". The word "comprising" in the description and in the claims is intended to include at least to some extent, and should be interpreted as including other features which may be present in addition to those mentioned later.

The application example provides a service data sending method, which realizes service data sending based on TCP long connection. The method can be applied to any equipment capable of serving as a data sending end, such as server equipment in an advertisement transaction platform (ADX), a supplier platform (SSP), a Demand Side Platform (DSP) and the like in an internet advertisement system, or various terminal equipment such as a PC, a tablet, a mobile phone, wearable equipment and the like.

Fig. 1 shows a system architecture diagram to which an example of the present application relates. As shown in fig. 1, the system architecture includes a transmitting end 101 and two receiving ends 102 (a receiving end 1 and a receiving end 2), where the receiving end 1 includes IP ports 1 to 3, and the receiving end 2 includes IP ports 4 to 6. The sending end 101 establishes TCP long connections with IP ports on receiving ends, respectively, to send service data packets (for example, various service requests such as accessing web pages and obtaining data) by using the TCP long connections, and the data volume of each service data packet is different, and the data volume of one service data packet is related to the current service processing needs, for example: a service request currently sent is delivered to the receiving end via a service data packet, and the data volume of the service data packet is determined by the data volume of the current service request. When a sending end prepares to send a service data packet, one TCP long connection is selected from each TCP long connection corresponding to the service data packet, and then the service data packet is sent through the selected TCP long connection. Such as: the service request to be sent currently corresponds to IP ports 1 and 2 in the receiving end 1 and IP port 4 in the receiving end 2, one of the

IP ports

1 and 4 is selected, and the service request is sent through the TCP long connection corresponding to the

selected IP port

1, 2 or 4. Here, two receiving ends and IP ports included therein are shown by way of example only, and the application does not limit the number of receiving ends and the number of IP ports on each receiving end. By IP port is meant a port in a network device identified by an IP address and port number, simply an IP port.

The embodiment of the application provides a service data sending method which can be used for the system architecture. The method can be applied to equipment as a data transmitting end. As shown in fig. 2, the method comprises the steps of:

step 201: and establishing a TCP long connection for each IP port of the data receiving end.

In some examples, when a device that is the data sender of a service starts the service, a long TCP connection is established for each IP port on the data receiver of the service. Here, a service may have multiple receiving IP ports, and these IP ports may be located in multiple machines in the server as the receiving end, or may correspond to multiple receiving processes on the same machine.

Step 202: a first weight is configured for each TCP long connection established in step 201.

Here, the first weight may be referred to as a target transmission weight or an expected transmission weight, and is configured according to the characteristics of each IP port, and may represent an expected value or a target value of a ratio of the number of times of transmitting the traffic packet to the total number of times of transmitting the traffic packet on the TCP long connection of one IP port. Such as: a first weight of a TCP long connection may be set to 0.2, which indicates that 1/5 traffic packets are expected to be sent on the TCP long connection. For a service data packet sent by a sending end, each IP port of a receiving end of the service data packet may be distributed on multiple devices or correspond to multiple receiving processes on the same device, so that data processing capabilities and response speeds of various devices or multiple receiving processes may be different, that is, capabilities of each IP port for receiving and processing data are different, and the first weight may be configured for a long TCP connection of each IP port based on the difference. Such as: because the response speed of the local device is high, high weight can be configured for the long TCP connection of the IP port on the local device. For another example: a higher weight may be assigned to TCP long connections for IP ports on devices with stronger processing power.

Step 203: when a service data packet is sent to the data receiving end, the following processing is executed:

in some instances, when a service request for a service (such as a request to access a page in a WeChat service) is sent, the following process may be performed. In the example of the present application, the data packets transmitted through the TCP long connection are in units of service requests, that is, one service request is transmitted through one service data packet, and the data amount of each service data packet is not necessarily the same.

Step 204: a second weight for each TCP long connection is determined. Wherein the second weight of a TCP long connection is determined according to the number of times the service data packet has been sent through the TCP long connection. Here, this second weight may be referred to as an actual transmission weight of the TCP long connection, and may represent a ratio of the number of times that the traffic packet is actually transmitted on the TCP long connection of one IP port to the actual total number of times of transmission. Such as: when 10 traffic packets have been sent (i.e. 10 times), 3 packets have actually been sent (and 3 times) over the long TCP connection, the second weight of the long TCP connection is 0.3.

Step 205: and selecting one TCP long connection according to the first weight and the second weight of each TCP long connection, so that the difference between the second weight and the first weight of the selected TCP long connection is smaller.

Step 206: the service data packet is sent through the selected TCP long connection.

In some examples, the number of times each TCP long connection has been sent is counted, so that in step 206, the number of times the selected TCP long connection has been sent may be further counted, such as by adding one to the count value. Thus, in step 204, the process of determining the second weight of each TCP long connection includes: and acquiring the count value of the sent times of each TCP long connection, and respectively calculating the second weight of each TCP long connection according to the acquired count value. Such as: the second weight of a TCP long connection is the ratio of the count of its sent times to the sum of the sent times of all TCP long connections.

In some examples, in step 205, a TCP long connection with the second weight having the largest difference from the first weight or having a difference reaching a certain threshold may be selected. In this way, the second weight of each TCP long connection gradually approaches to the respective first weight, even if the number of times that each TCP long connection actually sends the service data packet approaches to the expected value or the target value set for the TCP long connection in step 202 as much as possible, thereby achieving the purpose of load balancing.

In the above example, the first weight is configured for the TCP long connection of each IP port as the receiving end, and then when sending the service data packet, one TCP long connection is selected to send the service data packet according to the current second weight of each TCP long connection and the first weight configured in advance, so that the second weight of each TCP long connection gradually approaches to the respective first weight, and each service data packet is more reasonably distributed to each TCP long connection to complete sending, thereby achieving the purpose of load balancing, being able to more reasonably utilize system resources to process the service data packet, and improving the overall performance of the system.

In some examples, an initial value of the second weight (e.g., 0) may be further configured for each TCP long connection. In step 205, when the service data packet is transmitted through the selected TCP long connection, the number of times the TCP long connection has been transmitted is counted, and the second weight of the TCP long connection is calculated according to the count value. In step 204, the determining the second weight of each TCP long connection includes: the second weight (including the second weight calculated in step 205 and/or the initial value of the configured second weight) of each TCP long connection is obtained.

In some examples, the configuring of the first weight for each TCP long connection in step 202 includes: reading the configuration file, reading each IP port and the corresponding first weight from the configuration file, and configuring the read first weight to the TCP long connection corresponding to each IP port. Here, the pre-stored configuration file may be read from a local directory, and the configuration file may be a data table or an XML file.

In some examples, the configuring of the first weight for each TCP long connection in step 202 includes: and reading each IP port and the corresponding first weight from the memory, and configuring the read first weight to the TCP long connection corresponding to each IP port. Here, the process/thread for configuring the first weight may write the information of each IP port and the corresponding first weight into a shared memory, and in step 202, the process/thread for sending the service data packet may access the shared memory to read the first weight corresponding to each IP port.

In some examples, the configuring of the first weight for each TCP long connection in step 202 includes: and acquiring a configuration file from the configuration server, reading each IP port and the corresponding first weight from the configuration file, and configuring the read first weight to the TCP long connection corresponding to each IP port. Here, the configuration file may be obtained from an external configuration server, and the configuration file may be a data table or an XML file.

In some examples, the process of selecting a long TCP connection in step 205 may include: step A: and selecting a TCP long connection corresponding to a non-suspended IP port according to the first weight and the second weight of each TCP long connection.

In some examples, the step a may be followed by: and B: and D, judging whether the selected TCP long connection is disconnected or not, if so, suspending the IP port of the TCP long connection, and executing the step A again. Here, when it is determined that the TCP long connection is disconnected, the TCP long connection may have been selected for a plurality of traffic packets, and the TCP long connection is reselected for the traffic packets.

In this example, after the TCP long connection is selected, the temporary disconnection of the TCP long connection is also considered, the corresponding IP port can be suspended in time, and an appropriate TCP long connection is selected again, thereby ensuring the successful transmission of the service data.

In some examples, the process of selecting a TCP long connection corresponding to a non-suspended IP port in step 205 may include: and randomly selecting a TCP long connection corresponding to a non-suspended IP port from the TCP long connections with the second weight smaller than the first weight. Specifically, for the TCP long connection corresponding to each non-suspended IP port, the first weight and the second weight of the TCP long connection are compared, and one TCP long connection is randomly selected from the TCP long connections whose second weight is smaller than the first weight. The selection mode can make the actual sent weight of each TCP long connection gradually approach to the target weight, so as to achieve the effect of load balancing. Moreover, the selection mode is simple to realize and high in processing speed.

In some examples, the process of selecting a TCP long connection corresponding to a non-suspended IP port in step 205 may include: calculating the difference between the first weight and the second weight of each long TCP connection corresponding to each non-suspended IP port; selecting a TCP long connection with the largest difference between the first weight and the second weight. By the selection method, the actual sent weight (second weight) of each TCP long connection can be more quickly approached to the target weight (first weight), and a better load balancing effect is achieved.

In some examples, the process of selecting a TCP long connection corresponding to a non-suspended IP port in step 205 may include:

sequentially reading information (such as port numbers, state information and the like) of all IP ports;

when an IP port is read, the following processing is performed:

if the IP port is suspended, reading the next IP port;

if the IP port is not suspended, comparing the first weight and the second weight of the IP port, and if the second weight is smaller than the first weight, selecting the TCP long connection corresponding to the IP port.

In this selection method, simply, each IP port is polled, if the second weight of an IP port is found to be smaller than the first weight, the TCP long connection corresponding to the IP port is selected, the selection process is ended, and the information of the subsequent IP port is not read. The selection mode can enable the actually sent weight of each TCP long connection to gradually approach to the target weight, and the information of all IP ports does not need to be read, judged and compared every time, so that the processing efficiency is high, and a better load balancing effect is achieved.

In some examples, the process of suspending the IP port of the TCP long connection may include: the IP port is deleted from the list of non-suspended IP ports. Further, when the preset time is reached or the TCP long connection is recovered, the IP port is added into the non-suspended IP port list. Here, a list of non-pending IP ports may be set to maintain information on non-pending IP ports, and a pending IP port may be added back to the list at a regular time after a certain IP port is deleted from the list or when TCP long connection restoration is detected.

In some examples, the process of suspending the IP port of the TCP long connection may include: in the non-suspended IP port list, the status of the IP port is set as unavailable. Further, the state of the IP port is set to be available when a predetermined time is reached or the long connection of the TCP is restored. Here, a non-suspended IP port list may be set to maintain the state of non-suspended IP ports, and the suspended IP port may be restored to the state of available after the state of a certain IP port is set to unavailable or when TCP long connection restoration is detected.

In some examples, the step a may be followed by:

step B': and B, judging whether the selected TCP long connection is disconnected or not, if so, setting the first weight of the TCP long connection as a preset value so as to reduce the probability of selecting the TCP long connection, and then executing the step A again. Here, the first weight may be set to a very low value, such as 0 or 0.01, so that the second weight of the TCP long connection may be already equal to the first weight, and the TCP long connection will not be selected in the subsequent flow. The first weight may also be set to a lower value, so that the difference between the second weight of the long TCP connection and the first weight is not large, and if the difference between the first weight and the second weight is the largest or larger when selecting the IP port, the long TCP connection will not be selected for a while. This process of resetting the value of the first weight to make the TCP long connection less likely to be selected may also be referred to as a suspend-to-IP-port approach.

Fig. 3 shows a flow chart of a service data transmission process in an example of the present application. As shown in fig. 3, the following processes are included:

step 301: and the data transmitting end reads the target weight configuration of each IP port of the data receiving end, and further configures the target weight for each IP port. As mentioned above, the target weight is the first weight, and the configuration information of the target weight may be read from a configuration file, a memory, or an external configuration server.

Step 302: the data sending end establishes TCP long connection for each IP port.

Step 303: when a data sending end prepares to send a service data packet (such as a service request), the actual sending weight of the TCP long connection of each IP port is calculated according to the count value of the sent times. As mentioned above, the actual sent weight is the second weight, and the sent times of the long TCP connections can be counted, and the sent weight can be counted by using the count value.

Step 304: and selecting a TCP long connection of a non-suspended IP port according to a pre-configured weight algorithm. The specific selection method is described above, and the weighting algorithm may be: selecting the TCP long connection of the IP port with the largest difference between the target weight and the actual sent weight, selecting the TCP long connection of the IP port with the sent weight smaller than the target weight by polling or random selection, and so on, which are not described herein again.

Step 305: determining whether the selected TCP long connection is available (i.e., determining whether to disconnect), if so, performing step 307; otherwise, step 306 is performed.

Step 306: the currently selected IP port is suspended and the process returns to step 304 to reselect the TCP long connection for one IP port. Here, the specific suspend method is described above, and is not described here again.

Step 307: the service data packet is sent through the selected TCP long connection, and a count value of the number of times of sending the TCP long connection is added with one, and then the process returns to step 303 to send the next service data packet.

In the above example, the TCP long connection can be selected based on the target weight and the actual sent weight, so as to achieve load balancing, and meanwhile, the characteristic of temporary disconnection of the TCP long connection can be compatible, thereby ensuring data transmission performance.

Based on the above example of this application, this application has still provided a device. The device can be applied to the data transmitting terminal. As shown in fig. 4, the apparatus 400 includes the following modules:

the connection establishing module 401 establishes a long TCP connection for each IP port of the data receiving end.

And a weight configuration module 402, configured with a first weight for each TCP long connection.

The data sending module 403, when sending a service data packet to the data receiving end, triggers the weight determining module 404 and the selecting module 405 to execute the following processing:

a weight determining module 404, which determines a second weight of each TCP long connection; wherein the second weight of a TCP long connection is determined according to the number of times that the service data packet has been sent through the TCP long connection.

The selecting module 405 selects a TCP long connection according to the first weight and the second weight of each TCP long connection, so that a difference between the second weight and the first weight of the selected TCP long connection becomes smaller.

The data sending module 403 sends the service data packet through the TCP long connection selected by the selecting module 405.

In some examples, the apparatus 400, further comprises: and a counting module 406, configured to count the number of times the TCP long connection has been sent when the data sending module 403 sends the service data packet through the selected TCP long connection. The weight determining module 404 obtains a count value of the sent times of each TCP long connection, and calculates the second weight of each TCP long connection according to the obtained count value.

In some examples, weight configuration module 402 further configures an initial value of the second weight for each TCP long connection. The apparatus 400 further comprises: the calculating module 407, when the data sending module 403 sends the service data packet through the selected TCP long connection, counts the sent times of the TCP long connection, and calculates the second weight of the TCP long connection according to the count value. Wherein, the weight determining module 404 obtains the second weight of each TCP long connection calculated by the technique module 407.

In some examples, the selecting module 405 selects a TCP long connection corresponding to a non-suspended IP port according to the first weight and the second weight of each TCP long connection.

In some examples, the selecting module 405 further determines whether the selected TCP long connection is disconnected after selecting the TCP long connection corresponding to one of the non-suspended IP ports, and if the selected TCP long connection is disconnected, suspends the IP port of the TCP long connection, and re-executes the processing of selecting the TCP long connection corresponding to the one of the non-suspended IP ports.

In some examples, the selecting module 405 further determines whether the selected TCP long connection is disconnected after selecting the TCP long connection corresponding to one non-suspended IP port, and if the selected TCP long connection is disconnected, sets the first weight of the TCP long connection to a predetermined value to reduce the probability of the TCP long connection being selected, and then re-executes the processing of selecting the TCP long connection corresponding to one non-suspended IP port.

10. The method of claim 5, wherein the suspending the IP port of the TCP long connection comprises: setting the state of the IP port as unavailable in a non-suspended IP port list;

the method further comprises the following steps: and setting the state of the IP port to be available when a preset time is up or the recovery of the TCP long connection is detected.

11. The method of claim 4, wherein step A is further followed by:

B. and B, judging whether the selected TCP long connection is disconnected, if so, setting the first weight of the TCP long connection as a preset value to reduce the probability of selecting the TCP long connection, and then executing the step A again.

12. A traffic data transmitting apparatus, comprising:

the connection establishing module is used for establishing a Transmission Control Protocol (TCP) long connection for each IP port of the data receiving end;

the weight configuration module is used for configuring a first weight for the TCP long connection of each IP port according to the data processing capacity and the response speed of the equipment or the receiving process corresponding to the IP port;

the data sending module, when sending a service data packet to the data receiving end, triggers the weight determining module and the selecting module to execute the following processing:

the weight determining module is used for determining a second weight of each TCP long connection according to the number of times of sending the service data packet through the TCP long connection;

the selection module selects the TCP long connection with the largest difference between the second weight and the first weight according to the first weight and the second weight of each TCP long connection; and

and the data sending module sends the service data packet through the TCP long connection selected by the selection module.

13. The apparatus of claim 12, wherein the means for selecting selects a TCP long connection corresponding to a non-suspended IP port.

14. A computing device comprising a memory and a processor, the memory having stored therein computer-readable instructions that, when executed by the processor, implement the method of any of claims 1 to 11.

15. A computer-readable storage medium having computer-readable instructions stored thereon which, when executed by at least one processor, implement the method of any one of claims 1 to 11.
