Network request processing system and method

Abstract

The invention discloses a network processing request system, and relates to the field of Web services. The system comprises a session index unvarnished transmission module, a message metadata item order-preserving module and an active event notification module. The session index unvarnished transmission module and the message metadata item order-preserving module are executed in parallel; the session index unvarnished transmission module takes the session index as a new file descriptor used by the NGINX, and the NGINX takes the original file descriptor of the NGINX as the new session index tofind and access the session; the message metadata item order preserving module comprises a token number and an enqueue number, and checks the consistency of the token number and the enqueue number when the message metadata item is enqueued; the active event notification module comprises a VPP working thread which actively awakens an NGINX working process and an NGINX main process which actively awakens the NGINX working process, and actively inquires a mark in a user mode shared memory to confirm whether an AF_UNIX domain socket epoll event arrives or not. According to the method, the networkrequest processing performance is improved, and when no network request exists or the request amount is small, CPU resources are saved, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the network application field responsible for network request processing and load balancing at the edge of the network center in the field of Web services, in particular to a network request processing system and method. Background technique [0002] Thanks to the increasing number of mobile phones, smart watches, and Internet TVs, users' demand for access to various websites is also increasing. Huge website access requests put a lot of pressure on the website. At present, many websites use network applications that can forward requests to load balance network requests. NGINX is currently a widely used high-performance HTTP request forwarding and processing network application, and is used by many well-known websites for load balancing at the edge of the data center. The characteristic of NGINX is that it can maintain tens of thousands of connections with a small memory footprint. However, one of the currently popular soluti...

Problems solved by technology

[0006] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is that the lock mechanism used by the VPP LDP application interface affects the scalability of NGINX, and at the same time ensures that the control event message metadata items in the VPP event queue are not out of order after unlocking , and the energy waste and frequent context switching caused by the busy polling mechanism used by VPP's epoll event management
