Embodiment
The embodiment of the invention proposes a kind of inter-process communication methods, and referring to Fig. 3, Fig. 3 is the illustraton of model of interprocess communication of the present invention.This method does not need client process from DNS Server, to obtain the address of server; And the IPC module that only needs client is carried out internal searching (inner lookup), obtains the address of server, and afterwards, client process and server processes are set up interprocess communication.
In order to realize above-mentioned interprocess communication model; In the IPC of server module issue (publish) and cancellation issue (unpublish) mechanism are provided among the present invention; In the IPC of client module (lookup) mechanism of searching is provided; Be used to realize the address of the IPC module searches server of client, thereby set up interprocess communication between client process and the server processes.Referring to Fig. 4, Fig. 4 is the flow chart of embodiment of the invention inter-process communication methods.Comprise:
Step 401: after server processes were set up, server processes were sent to the IPC of server module and are intercepted (listen) message, started the relevant information of IPC module publisher server process.Wherein, It is existing technology in the prior art that server processes are sent listen message to the IPC of server module; In the prior art, generally speaking, send listen message and show that just server processes have carried out the preparation of setting up interprocess communication with client process; The IPC module of server will be waited for the IPC module transmission connect message of client afterwards, and interprocess communication is set up in request; But in the present embodiment; With the mechanism of listen message as the IPC module publisher server process relevant information that starts server; Certainly; Also can adopt other message that server processes are sent to the IPC of server module in the prior art, perhaps adopt the message of redetermination, as the mechanism of the IPC module publisher server process relevant information that starts server.
Step 402: IPC module broadcast distribution (publish) message of the IPC module of server all nodes in network; Carry the sign of server processes in this publish message, require the relevant information of all these server processes of IPC module records of this publish message of reception.
Step 403: after the IPC module of all nodes is received publish message in the network; Write down the sign of the server processes in this message and the corresponding relation of server address (because publish message comes from server; Therefore, the IPC module that receives this publish message can be known the address of server).
Step 404: after client process was set up, client process was sent to the IPC of client module and is initiated link order, requires the interprocess communication between foundation and server processes; The sign that comprises server processes in this initiation link order.
Step 405: the IPC module of client is according to the sign of the server processes of initiating to comprise in the link order, recorded corresponding relation in the finding step 403, the address that obtains server.
Step 406: the IPC module of client is sent connection (connect) message according to the address of the server that finds to the IPC of this server module.
After the IPC module of server was received connect message, the IPC module of IPC module, server processes and the client of server was cooperated each other, according to prior art in identical mode set up the interprocess communication between client process and the server processes.
More than introduced the process of setting up interprocess communication between client process and the server processes of setting up among the present invention, introduced server processes below and stop postrun subsequent processes.
Step 407: when server processes will stop operation, server processes were sent to the IPC of server module and are closed (close) message, started the issue of IPC module cancellation server processes relevant information.Wherein, Similar with the situation in the step 401; It also is existing technology in the prior art that server processes are sent close message to the IPC of server module, in the prior art, and generally speaking; Send close message and show that just server processes will stop operation, the IPC module of server will be waited for the interprocess communication of setting up before the IPC module request cancellation of client afterwards.In the present embodiment; With the mechanism of close message as the issue that starts IPC module cancellation server processes relevant information; Certainly; Also can adopt other message that server processes are sent to the IPC of server module in the prior art, perhaps adopt the message of redetermination, as the mechanism of the IPC module cancellation publisher server process relevant information that starts server.
Step 408: issue (unpublish) message is recalled in the IPC module broadcasting of the IPC module of server all nodes in network; Carry the sign of server processes in this unpublish message, the IPC module of the said message of requirement reception is removed the relevant information of said server processes;
Step 409: after the IPC module of all nodes is received unpublish message in the network, remove record (being the sign of the server processes of record in the step 403 and the corresponding relation of this server address) to these server processes.
Like this; When client process is sent the initiation link order to the IPC of client module once more; When requirement is set up interprocess communication with server processes,, can't find the address of this server because the IPC module of client has been removed the record to these server processes; Also just can't send connect message to the IPC module in this server, interprocess communication is set up in request.
Such scheme can shield the positional information of server processes, and is as shown in Figure 5, the position view of Fig. 5 client process and server processes during for interprocess communication of the present invention.When server processes and client process are carried out interprocess communication, can be arranged in (like P1 and the P2 of Fig. 5) on the same node, also can be arranged in (like P1 and P3 or P1 and the P4 of Fig. 5) on the different nodes; When client process was repeatedly carried out interprocess communication with server processes, the each position of server processes also can be different, and just server processes can be positioned on the different nodes.It is thus clear that; The inter-process communication methods that the present invention proposes and the location independent of server processes; Client process does not need the particular location of aware services device process, and server processes can arbitrarily distribute, and the advantage of this mode is: a plurality of server processes may operate on the different host node (node of runtime server process is called host node); All host nodes can be in active state, have realized that cpu load shares; On the contrary, on traditional distributed structure/architecture, because the position of server processes must be fixed, all usually server processes all operate on the movable host node, and other host nodes are all awaited orders, and this causes the cpu load of movable host node overweight.
In the said method; The sign of the server processes of carrying in the unpublish message of broadcasting in the publish message of broadcasting and the step 408 in the step 402 can be specially the port numbers of server; With 80 server processes is example; After 80 server processes started, the IPC module of server was broadcasted publish message, comprised the port numbers (i.e. 80 ports) of 80 server processes in this publish message; When these 80 server processes will stop operation, the IPC module of server was broadcasted unpublish message, comprised the port numbers (i.e. 80 ports) of 80 server processes in this unpublish message.
The embodiment of the invention also proposes a kind of interprocess communication system, and this system comprises client and server, and wherein client comprises the IPC module of client process and client, and server comprises the IPC module of server processes and server; Wherein,
Client process is used for sending the initiation link order to the IPC of client module;
The IPC module of client, the sign of the server processes that are used for comprising according to said initiation link order is searched the sign of the server processes of record and the corresponding relation of server address in advance, the address that obtains server; According to the address of server, send connection message to the IPC of server module, the interprocess communication between client process and the server processes is set up in request.
The IPC module of above-mentioned server is used for broadcast distribution message, and this gives out information and carries the sign of said server processes, requires to receive the relevant information of the said said server processes of IPC module records that give out information;
The IPC module of above-mentioned client can also be used to receive said giving out information, the sign of the server processes during record gives out information and the corresponding relation of this server address.
The IPC module of above-mentioned server can also be used for the broadcasting cancellation and give out information, and this cancellation gives out information and carries the sign of said server processes, and the IPC module that requires the said cancellation of reception to give out information is removed the relevant information of said server processes;
The IPC module of above-mentioned client can also be used for receiving cancellation and give out information, and removes the sign of the said server processes that write down in advance and the corresponding relation of this server address.
In the said system, server processes can be used for, and the IPC module broadcast distribution message or the broadcasting cancellation that start server give out information.
To sum up visible, issue (publish) message that server processes identify is carried by the IPC module broadcasting of server by inter-process communication methods and system that the present invention proposes; The sign of the IPC module records server processes of client and the corresponding relation of server address; Receive the initiation link order of client process transmission when client ip C module after, search recorded corresponding relation in advance, obtain the address of server according to the sign of the server processes that comprise in this instruction; Client ip C module is sent connection message according to the address of the server that obtains to the IPC of this server module, and the interprocess communication between client process and the server processes is set up in request.The mode that the IPC inside modules of the IPC module of server broadcasting publish message and client is searched server address among the present invention; Substitute client process in the prior art and obtained the mode of server address from DNS Server; Make client can obtain the address of server in time, and can not receive the influence of distributed DNS Server.Therefore, scheme of the present invention can adapt to the needs of distributed system, between client process and server processes, in time sets up interprocess communication efficiently.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being made, is equal to replacement, improvement etc., all should be included within the scope that the present invention protects.
