Embodiment
The connection for being under the jurisdiction of same virtual machine is referred to same by the present invention by creating connection pool for native virtual machine
In a connection pool, so that when any virtual machine is sent or receives message, the connection specified only is matched in corresponding address pool.
Due to avoiding whole connections of the local all virtual machines of traversal, so as to significantly improve the treatment effeciency to message.
The present invention will now be described in detail with reference to the accompanying drawings and examples.
Fig. 3 is referred to, the present invention proposes a kind of message processing method, applied to the network equipment, on the network equipment, institute
State method and perform following steps：
Step 301, be that connection pool is respectively created in local every virtual machine；
The connection for being under the jurisdiction of same virtual machine, be referred in the connection pool for the virtual machine creating by step 302；
Step 303, when local any virtual machine sends or receives message, based on the connection control for sending or receiving message
Information, matches corresponding connection in the connection pool, and by the linkup transmit matched or receives the message.
Fig. 4 is referred to, can be that a corresponding connection pool is respectively created in local every virtual machine in the present embodiment.
It is each to create the connection pool completed, can be by corresponding for converging all connections on the corresponding virtual machine of the connection pool
Virtual machine ID is searched.
Since each connection pool is used to converge all connections on corresponding virtual machine, it is therefore desirable to local every virtual machine
In connection carry out classification processing, the connection for being under the jurisdiction of same virtual machine is referred in corresponding connection pool.To local
When connection in each virtual machine sort out processing, it can be realized when local each virtual machine sends message.
Specifically, since the communication between virtual machine on different node devices is to be based on TCP/IP (Transmission
Control Protocol/Internet Protocol, transmission control protocol/Internet Protocol) come what is realized, therefore
Virtual machine on different node devices is in transmitting-receiving message mutually, it is necessary first to establishes TCP connections.TCP establishment of connections
Can be that virtual machine is directly created when starting and sending message；Can also be established before message is received and dispatched, start in virtual machine
When sending message, then connection is specified for the message from established TCP connections；Wherein, the specific of TCP connections establishes process,
The prior art is refer to, is no longer described in detail in the present embodiment.
In the present embodiment, when virtual machine starts to send message, can first check whether locally creating for the message
Connection is built or specifies, if creating or specifying connection for the message, then the company directly by having created or having specified
Receive and send the message；If not creating or specifying connection for the message, it is probably first message to show the message, then is the report
Text creates or specifies connection, and distributes corresponding connection control information from system resource for the connection.
Wherein, the connection control information generally comprises this message and sends local port number, the Peer-Port specified
Number, the information such as local host address and peer port number.Connection control information is connected and is assigned with when being specified for the message
Afterwards, the virtual machine ID in the message is obtained, the address pool created using virtual machine ID as index traversal, is searched and the virtual machine
Corresponding connection pool, after corresponding connection pool is found, will be added to the connection pool found for the connection that the message creates
In.
Certainly, in specific implementation, when sign off, virtual machine exit or process exits, it usually needs closing pair
The connection answered, therefore be somebody's turn to do when close event occurs for the connection in connection pool, it is necessary to be extractd in the corresponding connection pool of the connection
Connection, discharges resource.
After the classification connected in completing to local every virtual machine, converged at this time in each connection pool corresponding virtual
Whole connections in machine.However, the connection quantity in same virtual machine, generally depends on the business number that the virtual machine is carried
Amount.When the number of services that a virtual machine is carried is excessive, the connection quantity in the virtual machine also can be excessive, so as to cause every
The connection quantity of convergence in a connection pool is also excessive.
When the connection quantity converged in connection pool is excessive, virtual machine send or receive message matching connection when, it is necessary to
The connection of traversal certainly will increase, so that the treatment effeciency of message can be reduced.Therefore, in the present embodiment, can also be to connection pool
In connection be further grouped, to reduce virtual machine when receiving and dispatching message, travel through the quantity of connection.
, can be according to the local port in the connection control information of each connection when the connection in connection pool is grouped
Number and Peer-Port for parameter carry out Hash hash calculating, using the hash values calculated as key (i.e. described search key)
Each connection is grouped.
Specifically, Fig. 5 is referred to, respectively hash values can be calculated to every connection in connection pool according to the method described above,
Then the identical connection of the hash values calculated is organized in the form of doubly linked list in address pool, is divided into several companies
Packet is connect, each corresponding independent key value of connection packet.Certainly, when being grouped to the connection in address pool, having
Body can also use other packet modes when realizing, these are only a kind of illustrative embodiments shown in the present embodiment, not
For limiting the present invention.
Below in conjunction with embodiment, the detailed process that message is sent and received to virtual machine is described in detail.
In the present embodiment, for virtual machine when sending message, which enters system kernel state from the User space of virtual machine,
Enter the transport layer of system from physical layer, network layer.When transport layer handles received message, analytic message head first
Portion, obtains the virtual machine ID in the message, then travels through address pool by index of virtual machine ID, searches corresponding with the virtual machine
Address pool.Carried out after corresponding address pool is found, then using the local port number of the message and peer port number as parameter
Then time hash is calculated, and be key according to the hash values calculated, and corresponding connect is searched in the address pool found and is grouped,
The connection in connection packet is gone through, with regard to the connection specified can be matched.
For example, in a kind of preferable mode, can be by message in the connection during the connection that traversal is found is grouped
Local host address and opposite end host address as index value, the connection specified is matched in connection packet.Pass through local
Host address and opposite end host address, can accurately distinguish out in connection is grouped and specified connection is sent for this message.
Fig. 6 is referred to, after the connection specified has been hit in address pool, by the linkup transmit message, at the same time will
The message is put into the corresponding retransmission queue of this virtual machine, and retransmission sequence number is specified for the message, and activates retransmission timer, periodically presses
Order sends the message overstock in retransmission queue.
Wherein, what deserves to be explained is, retransmission queue can be placed under the message default situations that virtual machine is sent, when
After the confirmation ACK message for receiving message sink transmission, show that the message is successfully transmitted, need the message at this time from re-transmission
Removed in queue, and update the retransmission sequence number of other message in retransmission queue.
Equivalent, for virtual machine when receiving message, message enters transport layer by physical layer, network layer；Transport layer is being located
When managing message, analytic message head first obtains the virtual machine ID in the message, then using virtual machine ID for index traversal ground
Location pond, searches address pool corresponding with the virtual machine.After corresponding address pool is found, then with the local port number of the message and
Peer port number carries out hash calculating for parameter, is key according to the hash values calculated, the lookup pair in the address pool found
The connection packet answered, then travels through the connection in connection packet, matches the connection specified.Wherein, the company found in traversal
, still can be using the local host address in message and opposite end host address as index value, at this when connecing the connection in packet
The connection specified is matched in connection packet.
Fig. 7 is referred to, after the connection specified has been hit in address pool, system carries out sequence number inspection etc. to the message and passes
Defeated layer processing, if test serial number mistake, abandons the message.If sequence number is correct, further check the message whether disorderly
Sequence reaches, if the packet out-ordering reaches, then the message is put into the waiting list of this connection, the report arrived after out of order
Text.If the message reaches for order, then the message is directly put into the reception buffering area of socket Socket, is waited virtual
Application program in machine actively calls the message, and responds ACK messages to the receiving terminal of the message at the same time.
In the present embodiment, it is necessary to be done to the message when not receiving the ACK messages of receiving terminal response in sending cycle
Retransmission process, but in the prior art, multiple virtual machines in same node use same retransmission timer, virtual machine it
Between a kind of couple state is on protocol stack, it is easy to cause to retransmit the excessive situation of message.When the message of re-transmission is excessive, meeting
Retransmit several times, so as to cause the message that retransmits of certain virtual machine to be postponed situation about sending for a long time.Therefore, invention introduces
After connection pool, reduce the coupling on protocol stack between virtual machine, message can be carried out at re-transmission in units of connection pool
Reason, can effectively reduce the match time of physical link during message retransmission, be pushed away for a long time so as to avoid message is retransmitted
Tardy situation about sending.
In the present embodiment, when message is correctly processed in receiving terminal, and after being successfully put into the reception buffering area of Socket,
Can to message transmitting terminal carry out message confirmation, to the transmitting terminal respond ACK messages, transmitting terminal after the ACK messages are received,
Corresponding message is removed retransmission queue.Wherein message is carried out to the transmitting terminal of message confirm to be divided into transmission immediately and delay transmission
Two kinds, but in the prior art, in the case of delayed acknowledgement, traditional processing is still to be carried out in units of node, because
This can equally cause some virtual machines to be delayed the situation for carrying out message confirmation for a long time, so as to trigger as message retransmission
Virtual Machine Worker pauses.Therefore, in the present embodiment, message confirmation can be carried out to message in units of connection pool, to message
Transmitting terminal respond ACK messages, of physical link during message confirms can be effectively reduced after connection pool due to introducing
With the time, therefore the situation for carrying out message confirmation can be delayed for a long time to avoid some virtual machines.
As can be seen from the above description, the present invention will be under the jurisdiction of same virtual by creating connection pool for native virtual machine
The connection of machine is referred in same connection pool, so that when any virtual machine is sent or receives message, only in corresponding address
The connection specified is matched in pond.Due to avoiding whole connections of the local all virtual machines of traversal, so as to significantly improve to report
The treatment effeciency of text.Simultaneously as introduce address pool, the coupling on protocol stack between virtual machine can be effectively reduced, is carried
High the re-transmissions speed of message and the speed of message confirmation.
