For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Transparent interior interprocess communication protocol (Telecom Inter Process Communication; Abbreviate as: TIPC) being the transparent reliable host-host protocol of communicating by letter between a kind of implementation process, is the scheduling of basic realization task and resource with shared drive.The TIPC agreement is mainly used in communication between inner cluster (intra cluster), the TIPC agreement makes the different nodes that are in the same cluster (cluster) can consider residing position and directly carry out rapid and reliable communication, wherein, inner cluster (intra cluster) can be the distributed multi-processor system of any kind.For example, embedded system, it is a kind of application-centered, software and hardware can be reduced, be applicable to the dedicated computer system of application system, mainly form by flush bonding processor (being embedded central processing unit), relevant supporting hardware, embedded OS and application software system etc. to comprehensive strict demands such as function, reliability, cost, volume, power consumptions.
The TIPC agreement realizes based on socket (socket), when creating the socket connection, in kernel, register COS (service type) and the instance number that connects corresponding process with socket, and by TIPC address table of kernel maintenance, wherein the TIPC address is made of COS and instance number.When server is judged when receiving the TIPC protocol massages, obtain corresponding socket and connect according to resolving the TIPC protocol massages, connect according to this socket and carry out respective process.In cluster inside, every machine is all safeguarded a TIPC address table, like this, concerning application layer, the opposite end is corresponding to an address of being made up of COS and instance number, therefore client only need specify the COS of required invoked procedure and instance number just can be routed to corresponding process by the kernel of server, and need not know which IP address and which port have been used in this socket connection.
Further, the TIPC agreement is as the intra cluster communication agreement, have fireballing characteristics, but the remote procedure call function is not supported in the communication that is based between the integrated circuit board of TIPC agreement, based on this, the invention provides a kind of processing method, system and client, server of the remote procedure call of realizing based on the TIPC agreement, when solving the problem of well-known port restricted number that existing remote procedure call mechanism is subjected to server, realize the remote procedure call between the integrated circuit board, further improve the communication speed between the integrated circuit board.
The flow chart of the processing method of the remote procedure call that Fig. 1 provides for the embodiment of the invention one.The executive agent of present embodiment is a client, and as shown in Figure 1, the processing method that present embodiment provides comprises:
In the present embodiment, the TIPC address is the address of the server at required process place of calling, can realize by the type and the instance number of process, the i.e. server address that the TIPC address of being realized by the type of process and instance number can the required invoked procedure of unique identification place, and the corresponding required process of calling on the server.
This step is used for according to the server address at required process place of calling and calls the required parameter information of this process, generates the RPC call request, promptly carries above-mentioned information in this RPC call request.To use the most general RPC mechanism to be example, parameter information can be meant program number, version number and the process number of the required process of calling under the RPC mechanism, to confirm the required content of calling execution.
This step is used to realize the combination of TIPC agreement and RPC mechanism, is specially the RPC call request is encapsulated as the TIPC protocol massages; Simultaneously send call request to server, concrete gives server with the TIPC agreement with first message transmissions.The realization of TIPC agreement is usually based on the socket technology, and socket (socket) is equivalent to carry out the socket at the two ends of network service, as long as the other side's socket and the socket of oneself communicate to connect, both sides just can transmit and receive data.The specific implementation of socket: be similar to the definition of file handle, when the user uses the socket system call to write application program, represent a socket by a numeral, all operations are all carried out on this numeral, this numeral is called the socket file descriptor, and socket supports various protocols, for example based on the general socket of TCP/IP, UDP/IP agreement, the used socket of present embodiment is based on the socket of TIPC agreement, is mainly used in communication between plate.
Be example still with the most frequently used RPC mechanism, then required content by server by carrying out by parameter information: the well-determined process of program number, version number and process number obtains, and execution result is returned to client by the TIPC agreement, realize the remote procedure call between integrated circuit board.
The processing method of the remote procedure call that present embodiment provides, realize remote procedure call based on the TIPC agreement, utilize address in the TIPC agreement directly to point to process on the server, rather than be mapped to the characteristics of port, overcome the existing defective that is subjected to a limited number of restrictions of well-known port of server based on the RPC mechanism of TCP or udp protocol; Simultaneously, the RPC mechanism that realizes based on the TIPC agreement can be used between the integrated circuit board, realizes the remote procedure call between the integrated circuit board, in the communication speed that has further improved on the basis of TIPC agreement between integrated circuit board.
The flow chart of the processing method of the remote procedure call that Fig. 2 provides for the embodiment of the invention two, the executive agent of present embodiment is a server, corresponding to embodiment one, as shown in Figure 2, the processing method of present embodiment comprises:
Above-mentioned steps 21, step 22 are used to receive the message that comprises call request that client sends, and obtain call request by parsing, the specifically finger TIPC address that obtains in the call request to be comprised, and the relevant parameter information of the required process of calling; Wherein the process on the server can be by the type and the instance number unique identification of this process, and the TIPC address is to be realized by the type of process and instance number in the present embodiment, therefore this TIPC address not only can identify the server at required process place of calling, but and the type by process and the instance number corresponding required process of calling on the unique identification server also.
Server calls by the uniquely identified process according to parameter information, and carries out this process, obtains the execution result that RPC calls, and generates RPC and calls response, and by the TIPC agreement RPC response is returned to client.
The processing method of the remote procedure call that present embodiment provides, the processing method that provides with embodiment one adapts, by receiving the RPC call request of coming based on the TIPC protocol transmission, be encapsulated as the TIPC protocol massages through operation contents that client is required such as parsing, execution, encapsulation, be transferred to client based on the TIPC agreement by RPC mechanism, overcome the existing defective that is subjected to a limited number of restrictions of well-known port of server based on the RPC mechanism of TCP or udp protocol; Simultaneously, will can be used for the communication between the integrated circuit board, realize the remote procedure call between the integrated circuit board, in the communication speed of further having accelerated on the basis of TIPC agreement between integrated circuit board based on the RPC mechanism of TIPC agreement realization.
Further, in the foregoing description, between the server and client side a kind of connectionless communication mode, i.e. the direct call request after server sends encapsulation of client; Can also adopt connection-oriented communication mode between the client and server, concrete: set up between client elder generation and the server and follow communicating to connect of TIPC agreement, and this communicate to connect set up finish after, send call request to server, wherein the form of call request is specially the TIPC protocol massages.
Concrete, the client and server end is followed the TIPC agreement, and the TIPC address of pre-configured client and server end, and client and server is stored pre-configured TIPC address table, i.e. routing table respectively.During startup of server, each TIPC address of process binding with operation thereon, give client by TIPC communication protocol with the process of operation and the TIPC address notification of this process binding, after client is received this notice message, receive and with the information stores in this notice message in the TIPC address table; When the application process of client needs certain process on the invoking server, can be by inquiring about the TIPC address that local TIPC address table obtain required invoked procedure, and the processing method of the remote procedure call that provides by the embodiment of the invention realizes calling required invoked procedure.
Technique scheme provides a kind of execution mode of pre-configured TIPC address table, but is not limited to this.
At present, multiple RPC pattern and execution are arranged.Using the most general pattern now and carrying out is distributed computing environment (DCE) (the Distributed Computing Environment on open type software basis; Abbreviate as: DCE).Based on above-mentioned RPC pattern and execution, the TIPC agreement in conjunction with being realized by the socket technology describes technical scheme of the present invention in detail below.Before introducing technical scheme of the present invention, earlier the RPC mechanism that adopts among the present invention is simply introduced:
The information protocol of RPC is made up of recalls information and reply message; The RPC recalls information: every remote procedure call information comprises program number (Program number), program version number (Program versionnumber), three signless integer fields of process number (Procedure number), with independent identification remote process, described three signless integer fields are to be used for unique parameter information of determining required invoked procedure in the technical solution of the present invention.The RPC reply message promptly refers to carry out the content that the required process of calling obtains in embodiments of the present invention.
The flow chart that Fig. 3 provides for the embodiment of the invention three based on the RPC implementation method of TIPC agreement, present embodiment is described from the mutual angle of client and server, wherein adopt connectionless communication mode between the client and server, as shown in Figure 3, the RPC process of present embodiment comprises:
Step 31, server is created the RPC handle;
During the server starting up, at first create the RPC handle that meets server architecture, each parametric variable and function parameter in the RPC handle that for example SVCXPRT server handle, and initialization is created; For example, parametric variable: TIPC server end address (being the local terminal address); Server end socket handle etc.; Function parameter mainly is meant the initialization of the RPC handle being handled function, for example the functions such as function of receiver function, transmission function, deletion RPC handle.
Wherein, TIPC server end address can be pre-configured, and store a TIPC address table respectively at the client and server end, when server is started shooting the process of operation bound a TIPC address, and this message is sent to client.
Further, in order to solve the different problem of data format of the call request that different clients sends, in the present embodiment, carry out conversion between local data and the external data by calling External Data Representation, to overcome the problems referred to above.
Concrete, External Data Representation (External data representation; Abbreviate as: XDR) be a kind of data representation method that is independent of computer architecture, it is with transmitting the problems such as syllable sequence, data type size and alignment that data faced between the computer that solves different systems.Application program can use XDR to transmit data between the isomerization hardware system.
Step 32, server is registered the handle of being created;
In this step server with the server RPC handle information created with the socket handle be index stores in an array, array XPRT for example; Have mapping relations between the socket of described server RPC handle and the socket of client, the socket 2000 of the socket 1000 corresponding with service device RPC handles of client RPC handle for example, therefore, can find corresponding relation between client RPC handle and the server RPC handle by socket.
Step 33, server enters wait state, waits for that client sends call request message;
Step 34, client is created the RPC handle;
Client is created the RPC handle, is specially to create the RPC handle that meets client (CLIENT) structure, and each parametric variable and function parameter in the RPC handle created of initialization; For example, parametric variable: TIPC server end address promptly will connect the address of the server of communication; Client socket handle etc.; Function parameter mainly is meant the initialization of the RPC handle being handled function, for example be used to send transmission (call) function of client-side information, for example, be used for reception (reply) function of the information that reception server sends, and deletion (delete) function etc. that is used to delete the RPC handle.
Step 35 is created the XDR internal memory, to carry out conversion between native data formats and the external data form by calling External Data Representation (XDR);
This step is corresponding to the processing of local data and external data with server end, by cooperating the data interaction that realizes between client and the server.Wherein, for client, local data is meant the RPC call request of formation, and external data is meant the RPC call request after the process format conversion that sends to server; And for server, external data be meant receive represent the RPC call request by what client was sent with the XDR data format, local data is meant through XDR mechanism and data is carried out the RPC call request that obtains after the format conversion.
Step 36, user end to server send the RPC call request, and waiting for server is returned RPC and called response;
Concrete, client is with the address of the server at required invoked procedure place, and the program number, version number, the process number generation RPC call request that are used to identify this process, and carries out the XDR format conversion, and be encapsulated as after the message that is fit to the TIPC agreement, send to server.
Step 37, the message of following TIPC agreement of server to receiving;
Concrete, the socket handle of the message of following the TIPC agreement that the client that the server basis listens to is sent, with this socket handle is to index the RPC handle of searching the corresponding server end in the array of server, is used to receive the message of following the TIPC agreement that client sends;
The server parses message obtains the RPC call request, is native data formats to this RPC call request by the XDR mechanism transformation then, and obtains the parameter information of required invoked procedure, specifically refers to program number, version number and process number.
Step 38, server calls corresponding process according to parameter information, obtains the required content of client;
Step 39, server calls response to the RPC that returns of client;
Server forms RPC with result and calls response, and is the external data form by the XDR mechanism transformation, generates the message of following the TIPC agreement, sends to client by the TIPC agreement.
Step 40, the message that the client reception server sends, and carry out dissection process, obtain required content;
After client receives the message that server sends, earlier this message is resolved and obtain RPC and call response, and be native data formats, obtain required content, carry out corresponding operation according to the content of being obtained by the XDR mechanism transformation.
If a plurality of call request are arranged, then by on a plurality of call request recursive call servers with the corresponding process of call request, all finish up to all invoked procedures.
Step 41, client finishes this remote procedure call to server with the RPC handle deletion of being set up.
At this moment, server enters wait state, waits for follow-up RPC call request message.
Present embodiment has been introduced client and server and how have been realized calling of remote process by technical scheme of the present invention, the address of TIPC agreement is not mapped to TCP or udp port in the technical solution of the present invention, therefore is not subjected to the restriction of the well-known port quantity of server based on the RPC mechanism of TIPC agreement; Simultaneously, reduced the operating process of obtaining port to server, compared with prior art, the efficient of the remote procedure call that technical solution of the present invention provides is higher;
In addition, RPC can't directly set up Socket with server and communicates by letter in the prior art, needs auxiliary other technologies know that in advance RPC starts the port numbers that the back obtains, and can't directly send call request by RPC, influence the speed of interprocess communication.Therefore, existing RPC mechanism is subjected to the restriction of TCP or udp protocol, the remote procedure call between the integrated circuit board that is unsuitable for communication speed is had relatively high expectations.Present embodiment is that the TIPC agreement realizes that therefore, technical solution of the present invention can realize the remote procedure call between integrated circuit board, further quickens the communication speed between integrated circuit board based on communication protocol between integrated circuit board.
