Problems solved by technology

[0004] At present, the access layer of the monitoring product uses NGINX as the front-end SIP gateway, which plays a load balancing role. However, in actual use, it is found that the CPU load of the NGINX server is also high during operation. In addition, SIP is based on the UDP protocol. Packages are also common

Abstract

The invention discloses a method for improving the performance of a SIP gateway based on the DPDK technology. The DPDK protocol stack is realized in accordance with the DPDK programming mode, and the polling mode is adopted without interruption. Each traversed entity and its messages can be processed very quickly. The protocol stack and NGINX are bound to each CPU core when starting, making full use of the optimization of DPDK and CPU cores to reduce the overhead of thread scheduling. The communication between the protocol stack and NGINX two processes of the present invention uses the lock-free queue provided by DPDK, and the communication timeliness is high. The present invention is based on DPDK technology, bypasses the LINUX system, directly captures packets from the network card to the application layer, and forwards the data packets to the DPDK protocol stack of NGINX, reduces the CPU load and reduced packet loss rate of the SIP gateway, and is suitable for The traffic volume requires communication timeliness and low packet loss rate gateway scenarios.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method for improving the performance of a SIP gateway based on DPDK technology. Background technique [0002] In a traditional Linux symmetric multiprocessor (SMP) environment, multiple CPUs run a single copy of the operating system, and each CPU shares the memory subsystem and bus architecture. As the number of CPUs increases, the problem of shared resources or I / O synchronization between CPUs becomes more and more obvious, resulting in high system overhead, which prevents the processing performance of data packets from increasing linearly with the increase in the number of processor cores. [0003] DPDK is an open source rapid packet processing development tool set, which implements a complete set of bypass real-time operating environment based on LinuxOS but different from Linux OS, not a network protocol stack. Applying DPDK technology to efficiently process network d...
