Method and device for establishing strategy template table, and session processing method and device

Abstract

The invention provides a method and device for establishing a strategy template table, and a session processing method and device. When a session connection table entry of a session to which a message belongs cannot be searched in a session list, a message forwarding platform searches whether an available strategy template corresponding to an IP address exists in a strategy template table or not, according to the IP address of the message; if the available strategy template exists, the message is sent to a strategy matching platform; the IP address and a session strategy corresponding to the IP address sent by the strategy matching platform are received; a session strategy template is established; and the session strategy template is stored in the strategy template table of the message forwarding platform. At least one session strategy template is stored in the strategy template table. The session strategy template comprises a corresponding relationship between the IP address and the session strategy. For different newly established sessions with the same IP address, the required session strategy template is obtained from the strategy template table without waiting for the strategy matching platform to issue the session strategy, and the data interaction between the message forwarding platform and the strategy matching platform is reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and device for creating a policy template table, and a method and device for session processing. Background technique [0002] In the public domain, when a packet is received, the packet is forwarded based on the session connection entry of the session to which the packet belongs, and the session connection entry is created based on the session policy of the session. In general, because forwarding a message based on the session connection table is a fast process, but setting a session policy for the session to which the message belongs is a slow process. Therefore, the above two processes are carried out on different platforms. Processing, that is, using heterogeneous platforms for processing. [0003] like figure 1 As shown in FIG. 1 , take a heterogeneous platform in the user mode and another heterogeneous platform in the kernel mode as an example to illustrate...

AI Technical Summary

Problems solved by technology

[0004] When a large number of new sessions are created concurrently, the processing speed of the first thread and the second thread is limited, and the policy generation platform (kernel mode platform) can only establish session policies at a limited speed, and the message forwarding platform (user mode platform) can only wait for the policy to be generated The platform (kernel mode platform) sends the matching session policy to each new session. For the new session with the same source IP address and destination IP address, the same session policy is generally adopted, so the packet forwarding platform will receive A large number of repeated session policies issued by the session policy platform lead to slow creation of session connection entries and affect the speed of message forwarding
