A method for network communication session aggregation

Abstract

The present invention provides a method for network communication session aggregation, including creating a data structure about the master session and the slave session; associating the master session with the slave session according to the created data structure, and associating the rules of the master session with the slave session to obtain Master session node and slave session node; if the dynamic port has a protocol, establish a slave session node associated with the master session; if there is a new session, associate the slave session with the corresponding master session; The data structure of the session information; associating the upper-level component with the corresponding master session; creating the data structure of the upper-level component; the upper-level component obtains the association relationship between the master session and the slave session. It can be widely applied to various types of dynamic port protocols. Realize the association aggregation of master session and slave session, so that the association relationship between sessions can be obtained in receiving data and subsequent processing. The protocol to which the data session belongs can be known when the protocol characteristics of the secondary session (data session) cannot be determined.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method for network communication session aggregation Background technique [0002] The so-called session association refers to the establishment of the same protocol, which will establish a session of multiple protocol connections. Usually, there are communication protocols with dynamic port opening, such as FTP and OPCClassic. Taking FTP as an example, an FTP application includes a control channel session and several data channel sessions. When performing FTP access, establish the session connection of the control channel first, and then dynamically establish the connection of the data session when file data needs to be transferred. Since the port of the communication session established at this time is obtained through message negotiation or randomly assigned, this type of protocol is also called a "dynamic port" protocol. [0003] Because it is a "dynamic ...

AI Technical Summary

Problems solved by technology

[0004] Existing session processing technology: session information is stored and displayed independently, session information is stored independently and controlled independently Disadvantages:

[0006] 2. Since the master session and the data session are not related, it is impossible to know which communication protocol belongs to the slave session without protocol / port characteristics

[0007] 3. For monitoring and auditing equipment / security control equipment, it is impossible to automatically map the rules of the main session to the data session to take effect
