Embodiment Construction

[0043] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] When the server and the client are connected using a stateless network protocol, the present invention establishes a session node in the connection status table (CST Connection Status Table) of the simulated connection layer of the server, and the server temporarily stores the data information to be sent to the client to the session node , the client sends the request information to the server, and the server carries the data information in the reply information. The invention enables the server to actively send data information to the client in the client and server connected based on the stateless network protocol, so as to realize some functions of the stateful connection.

[0045] Referring to FIG. 2 , it is a flowchart...

Abstract

The method for simulating connection with status based on connection without status includes following steps: connecting server to client end based on network protocol without status, and establishing conversation node in connection state table at simulating connection layer of the server; the server stores data information prepared to send to client end to the conversation node temporarily; the client end sends request information to the server, and the reply information of the server carries the said data information so as to realize connection with status between the server and the client end. Under condition based on connection between client end and server in network protocol without status, the invention makes server possible to send data information to client end on initiatively so as to realize partial function of connection with status.

Description

technical field [0001] The invention relates to the field of network protocols, in particular to a method and system for simulating a stateful connection based on a stateless network protocol. Background technique [0002] A stateless network protocol means that the two parties in the network connection do not maintain a stateful connection. Each time information is exchanged, one party needs to send a request message to the other party. After the other party returns a response message, both parties close the connection. Such as HTTP (Hypertext Transfer Protocol) application protocol, UDP (User Datagram Protocol) protocol. In many practical applications, this stateless network protocol is used to connect between the client and the server. In this way, only when the client actively sends request information to the server, the server can return the response information, and the server cannot actively send operation information to the client. end. [0003] Referring to FIG. 1...
