Method for improving new performance of network communication equipment

Abstract

The invention discloses a method for improving new performance of network communication equipment. A Fast _ l2 module packet sending method is explained by comparing a standard protocol stack packet sending method; According to the method, Ethernet and vlan header information is added to a data packet in a Fast _ l2 module according to stored link state information; then, a drive packet sending function ndo _ start _ xmid is directly called to send out a corresponding data packet, related processing of the whole protocol trestle and vlan is skipped over, memory use and CPU consumption of protocol stack two-layer processing data packets are reduced to a certain extent, and therefore product newly-built performance is improved; In addition, the kernel module compiled by the method occupies asmall memory, network communication equipment with a relatively tense memory can be loaded, and the transportability is high; A hook point is only required to be hung at an ip _ finish _ output2 function to take a data packet; defining a fast _ 11 _ ext pointer variable in a link tracking step nf _ conn structure body, taking two-layer cache information of the link for packet sending, and enabling a kernel module compiled by the method to be low in coupling.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a method for improving the new performance of network communication equipment. Background technique [0002] Performance is the most direct evaluation to measure the quality of a network communication device. The performance indicators mainly include throughput, message forwarding rate, maximum number of concurrent connections, number of new connections per second, forwarding delay, jitter, etc. [0003] In the fiercely competitive communication equipment market, in order to improve the user's online experience and enhance the competitiveness of the network communication equipment market, it is necessary to use the same hardware resources or cost to create higher-performance equipment in order to stand on the top of the wave in the field of communication equipment . [0004] In the case that the CPU and memory have been determined, the current performance tuning of new n...

AI Technical Summary

Problems solved by technology

[0009] (1) After adjusting the kernel proc directory parameters, code optimization and other solutions, the data packet forwarding of the network device still needs to go through the protocol stack. When the amount of data is huge, the consumption of memory and CPU is particularly obvious, and the forwarding efficiency is low, which affects the performance of new creation

[0010] (2) Some low-end network equipment, especially home communication products, have poor memory and CPU, and the new product capability is not up to the standard level. Some methods are urgently needed to optimize the new performance to improve the market competitiveness of the product
