Abstract

The invention discloses a method for concurrently identifying and processing sub-joins in multi-core systems, comprising the following steps of: presetting a sub-join state machine strategy and correspondingly managing the states of sub-joins information nodes by using a parent join according to the sub-join state machine strategy; establishing a parent sub-join tree, saving a pointers of the information nodes of an application protocol of the parent join in parent join information nodes and saving the pointers of all sub-join information nodes established by the application protocol in the information nodes of the application protocol; setting a relational tree lock for the whole parent join tree, wherein the establishment and the recovery of the relational tree lock are carried out whenan original join is established and recovered; and setting reference counters for all relational trees and releasing the relational tree lock when a reference timer is zero. The method effectively improves the performance of identifying and subsequently processing the sub-joins in a control join and the concurrent processing capability of the systems.

Description

technical field

[0001] The invention relates to application protocol processing and identification technology in network communication, in particular to a method for concurrent identification and processing of multi-core sub-connections. Background technique

[0002] The multi-connection protocol means that during the completion of the protocol, in addition to a main communication channel (parent connection), some channels (sub-connections) will be dynamically opened for communication. Firewalls need special processing for these protocols to ensure security.

[0003] The multi-connection protocol can also be divided into mandatory sub-connection and non-mandatory sub-connection. Mandatory sub-connection means that the establishment of sub-connection is necessary, and communication will not proceed normally without establishing sub-connection, such as FTP; non-mandatory sub-connection refers to sub-connection The establishment of the main connection is not necessary. The main...
