Description

Network communication method and equipment

Technical field

This application involves computer field more particularly to a kind of network communication method and equipment.

Background technique

Remote procedure call (RPC, Remote Procedure Call), using client (Client)/server-side (Server) mode.The content of communication between Client and Server is message (Message), is usually convenient for business processing Architectural entities.

As shown in Figure 1, typical RPC process is as follows:

(1) Client, which is called, initiates RPC request to Client stub (client communication agency) with local method of calling (rpc call)；

(2) Client stub (client communication agency) receive calling after by request message sequence be melted into it is continuous sheet of Byte stream (bundle Args), to facilitate tcp to transmit；

(3) Client stub finds address of service, and is sent message by network service (Network Service) (send) server-side (Server) corresponding Server stub (server-side communication agent) is arrived；

(4) after Server stub receives message, antitone sequence dissolves request content (unbundle Args) from byte stream；

(5) Server stub calls local server-side (Server) according to the request content that antitone sequence dissolves, and processing is asked Ask (local call)；

(6) local server-side executes request and processing result (local return) is returned to Server stub and makees For response；

(7) Server stub will return the result sequence chemical conversion byte stream (bundle ret vals), return to client Corresponding Client stub (client communication agency)；

(8) Client stub receives response message, and carries out unserializing (unbundle to the response message ret vals)；

(9) response message is sent to Client (rpc after carrying out unserializing (unbundle ret vals) Return), Client obtains final result i.e. response message.

In above process, before sending message, to be byte stream to message sequence, be used for tcp (Transmission Control Protocol transmission control protocol) transmission；After receiving (receive) message, byte stream unserializing is used for Business processing.Specifically, message serialize and the process of unserializing is as follows:

During message sequence, successively parameter information (params) is encoded, and is formed with data block (data) Continuous sheet of byte stream is transmitted for tcp and is used.It needs exist for copying data block, data block is more, copies more. In message as shown in Figure 2, there are two data block (data), shared to copy twice.For writing IO (input and output) request, When Client (client) has transmission message sequence, because client will write data to client, ginseng is had in write request Number information and data, so having data copy (memcpy), for example, thering is Data1, Data2 as shown in Figure 2 to copy；And Server When (server-side) replys write response serializing, because only replying write-in as a result, only having parameter information not count in return information According to so no data copies, for example, without the copy of Data1, Data2 as shown in Figure 2；For reading IO (input and output) request, When Client sends message sequence, because only having parameter information not have data in write request, no data is copied, for example, There is no the copy of Data1, Data2 as shown in Figure 2；And Server (server-side) is replied when reading response sequence, because to reply The data read, so parameter information and data are had in return information, so having data copy, for example, having as shown in Figure 2 Data1, Data2 copy.

Correspondingly, during message unserializing, parameter information is successively decoded from byte stream, and by data block copy To suitable position, it to be used for business processing.Likewise, data block is more, copy more.As shown in figure 3, being to receive disappearing for Fig. 2 The process of unserializing is carried out after breath.For writing IO (input and output) request, Server (server-side) receives write request antitone sequence When change, because having parameter information and data in write request, there is data copy (memcpy), for example, having as shown in Figure 3 Data1, Data2 copy；For reading IO (input and output) request, when Client (client) receives response unserializing, because The data read are received, so parameter information and data are had in the return information received, so have data copy, for example, There are Data1, Data2 as shown in Figure 3 to copy.

When containing more data in above scheme, in message, especially IO size (inputoutput data amount) biggish reading The expense of write request, data copy (memcpy) can not be ignored.In IO critical path, there are data at Client and Server two Copy, at least data copy is primary (depending on number of data blocks) again at every place, seriously consumes cpu (processor) and memory (memory) resource, drain performance are write delay and are increased, IOPS (Input/Output Operations Per Second), i.e., The number per second being written and read) it reduces.
