Embodiment Construction

[0041] The core idea of ​​the present invention is to effectively control the connection life cycle and connection state transition through the comprehensive use of fine-grained read-write locks, spin locks, connection reference counts, and memory barriers, so that multiple cores can provide data when sharing the same connection. Integrity and consistency to ensure the correctness and performance of multi-core data communication and control processes.

[0042] In order to facilitate the understanding of the methods described in the embodiments of the present invention, several important concepts involved in the present invention are briefly introduced first.

[0043] 1. Fine-grained lock

[0044] The connection table of the present invention is used concurrently by multiple cores. In order to reduce the impact of locks on system performance, fine-grained locks are used to minimize the locking range. The main reasons are:

[0045] Such as figure 1 as shown, figure 1 It is a ...

Abstract

The invention discloses a method for concurrently processing a join in multi-core systems. The method is used for effectively controlling a join life cycle and join state conversion through the comprehensive use of a fine-grained read-write lock, a spin lock, a join reference counter and a memory barrier so that the multi-core systems provide the integrity and consistency of data when sharing thesame join, and the correctness and the performance of the communication and control process of multi-core data are ensured.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for concurrently processing connections under multi-core. Background technique [0002] Generally, a connection refers to a set of stored information established for fast forwarding during network communication. Source address, destination address, source port, destination port, protocol and other control information required for transmission constitute a connection. [0003] Multiple connections form a connection table. Generally, when receiving the first message, the source address, destination address, source port, destination port, and protocol are obtained through the accepted network message, and the hash (hash) value is calculated according to the above five elements, and the connection table is queried. The connection exists, query the control information of the connection, and directly forward or discard the message according to the control information, ...
