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 an SIP (Session Initiation Protocol) gateway based on a DPDK (Digital Protocol Data Kit) technology, which follows a DPDK programmingmode to realize a DPDK protocol stack and adopts a polling mode without interruption. Each traversed entity and its message can be quickly processed. The protocol stack and the NGINX are bound with each CPU core when being started, so that the optimization of the DPDK and the CPU cores is fully utilized, and the scheduling overhead of threads is reduced. The lock-free queue provided by the DPDK isused for communication between the protocol stack and the NGINX process, and the communication timeliness is high. The method is based on the DPDK technology, bypasses an LINUX system, directly captures packets from a network card to an application layer, forwards the data packets to the DPDK protocol stack of the NGINX, reduces the CPU load of the SIP gateway and the packet loss rate, and is suitable for scenes with large telephone traffic, communication timeliness requirements and low packet loss rate gateways.

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...
