Problems solved by technology

NAT gateways are usually deployed in clusters, and for bidirectional traffic loaded on a certain NAT, related technologies store all session tables in the memory of the CPU, all cores of the CPU can access, and randomly select a thread to implement routing Conversion and traffic forwarding, and the two-way packets of the same routing link cannot be distributed to the same processing thread. Each thread needs to call the session table with each other, which is easy to trigger the read-write lock mechanism for CPU multi-core access, increasing the authentication time. Reduce processing efficiency, and multi-core CPU resources are not fully utilized, and the load among multiple cores is unbalanced
[0004] For the above-mentioned problems existing in related technologies, no effective solution has been found yet

Abstract

The invention discloses a message forwarding method and device, a storage medium and electronic equipment, and belongs to the field of communication. The method comprises the following steps: receiving a message to be forwarded; analyzing the data flow direction of the message; if the data flow direction is an outflow direction, performing hash calculation on meta-information contained in the message to determine a processing thread of the message; if the data flow direction is an inflow direction, determining a processing thread corresponding to the data flow where the message is located in an outflow direction according to a mapping relationship between a destination port and the processing thread, each processing thread being bound with a processor core; and forwarding the message on the processing thread by adopting a preset session table. Through application of the message forwarding method and device, the technical problem of low message forwarding efficiency of a multi-core CPU in related technologies is solved, and the message forwarding speed and the message processing efficiency are improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a message forwarding method and device, a storage medium, and electronic equipment. Background technique [0002] In related technologies, with the development of server-level processors (CPUs), using multi-core platform CPUs for software gateway forwarding has become a common standard in the cloud computing industry. Software forwarding has the advantages of fast development cycle, flexible business processing, and high performance. How to evenly distribute business traffic to each CPU core has become a key technical realization for making full use of server hardware performance. [0003] In related technologies, NAT (Network Address Translation, Network Address Translation) gateway is a key technology in cloud computing. address), but now you want to communicate with hosts on the Internet, you can use the NAT method to install NAT software on the router that connects the pr...
