Problems solved by technology

[0004] In addition, if the PBAR identification of the received message for establishing a session does not identify the application, the session will be created directly, and session management cannot be performed based on the application, which may cause too many sessions to be established under the application corresponding to the message. situation, thereby affecting normal business processing

Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0026] At present, if the PBAR identification of the received message for establishing a session does not identify the application, the session will be created directly, and session management cannot be performed based on the application, which may cause too many sessions established under the application corresponding to the message. situation, thereby affecting normal business processing.

[0027] In order to reduce the situation that too many sessions are established and reduce t...

Abstract

The embodiment of the invention provides a session management method and device, and relates to the technical field of communication. The session management method comprises the steps of receiving traffic; searching a first application corresponding to the target address of the traffic from a pre-stored corresponding relationship between addresses and applications; obtaining a session management strategy which matches the first application and obtaining a session number threshold value from the session management strategy; if the number of the built sessions in the first application is greaterthan the session number threshold value, deleting the session corresponding to the traffic. By applying the embodiment, the condition of building excessive sessions is reduced, and influences on normal services are reduced.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a session management method and device. Background technique [0002] APR (Application Recognition, application layer protocol recognition) includes PBAR (Port BasedApplication Recognition, port-based application layer protocol recognition) and NBAR (Network BasedApplication Recognition, application layer protocol recognition based on content characteristics). [0003] At present, session management is performed after PBAR identification, that is, PBAR identification is performed on the received message used to establish a session (such as the SYN message in the three-way handshake message), and if the application is identified, session management is performed according to the application , to obtain the session management policy matching the application, the session management policy includes the session number threshold, if the number of established session...
