A method for improving the new performance of network communication equipment

Abstract

The invention discloses a method for improving the new performance of network communication equipment, which illustrates the Fast_12 module packet sending method by comparing the standard protocol stack sending method; the present invention adds Ethernet and vlan headers to data packets in the Fast_12 module according to the saved link state information information, and then directly call the driver packet sending function ndo_start_xmit to send the corresponding data packet, skip the related processing of the entire protocol stack bridge and vlan, to a certain extent reduce the memory usage and CPU consumption of the second layer of the protocol stack processing data packets, thereby improving New product performance; in addition, the kernel module written by this invention occupies less memory, and can be loaded by network communication devices with relatively tight memory, and has high portability; and it only needs to hang the hook point at the ip_finish_output2 function to fetch data packets, and link Track the struct nf_conn structure and define the fast_l2_ext pointer variable to fetch the second-level cache information of the link for packet sending. The kernel module written by this method has low 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
