基于事件驱动的高性能WebSocket服务器的设计与实现
DESIGN AND IMPLEMENTATION OF EVENT-DRIVEN HIGH PERFORMANCE WEBSOCKET SERVER
摘要
Abstract
In recent years,instant messaging has been more and more widely used on the Internet.The Pull model adopted in the traditional servers cannot well meet the requirements of real-time information acquisition and high concurrent using accesses in the practical applications.In order to deal with the aforementioned problem,using the Push model in the real-time message transmission has become a research hotspot.Based on open source projects of Node.js,Redis and RabbitMQ,a WebSocket server is designed and implemented.The WebSocket server can provide real-time message push service to a large number of different users' subscription requests.In the WebSocket server,the Node.js multi-process management module is modified.Experimental results show that when a single WebSocket server handles more than 1 000 concurrent connections,the dislocation rate is around 1.52％,which effectively achieves the high concurrency and stability of the WebSocket server.关键词
