Embodiment one:
The network communication method that Fig. 1 provides for the embodiment of the present invention realize schematic diagram, details are as follows:
1. host-host protocol is set for multiple end points;
In embodiments of the present invention, before being transmitted, need arrange host-host protocol to multiple end points is TCP or udp protocol, when needing to change host-host protocol, only need arrange new agreement to end points.No matter use Transmission Control Protocol or udp protocol, the occupation mode of end points is all consistent.Described end points is network communication terminal, has unified the concept of client and service end in prior art network interface, no longer distinguishes client and service end in data transmission procedure.In order to can in TCP with udp protocol occupation mode the same, shielding client and the difference of service end, end points has done following improvement:
First, end points place can arrange different host-host protocols.Needed for actual development, Transmission Control Protocol or udp protocol can be set using at end points.If need on stream to change agreement, also only another host-host protocol need be set at end points place.
Secondly, due to when using Transmission Control Protocol, have the difference of client and service end, end points has done again the improvement of following two aspects.
The first, end points can listening port.All end points can both listening port, and by monitoring, can accept connect Please summed data, possess the ability of server, therefore, all end points all can be used as service end.No matter the end points at this moment as client sends information to any one end points, this end points all has the function of service end, can accept connect Please summed data.And in actual applications, according to required, judged as client or as service end by the monitoring of whether opening local port.
The second, containing event handler in end points.When have connection request occur, data arrive or connection closed, make mistakes time, end points can realize the function logic of application definition by callback events processor automatically.Due in Transmission Control Protocol, client can not perception have data to send to oneself, therefore first can not send data by service end.In the embodiment of the present invention due in end points containing event handler, then when first sending information by the end points as service end to client, as the end points of client also by event handler perception with receive data.
Be key as the end points of service end with client ip address, all clients of buffer memory are initiated, and current effective connection.When initiation session first as the end points of service end, according to the IP address of the target endpoint that will send, from buffer memory, take out existing connection, structure session transmissions data.
Known based on foregoing description, end points shields the difference of client and service end in TCP, and any one end points both can also can as service end as client.No matter and be first can send data as client or as service end.
