Research On High Concurrent System Based On Node.js

With the arrival of mobile Internet,people began to use a variety of Internet products to change their way of life,a variety of Web traffic is growing,the domestic Taobao,Baidu,foreign Facebook,Twitter,and Google,how to face each Sec million or more concurrent traffic to provide good access to the user experience has become the most difficult types of network applications one of the problems.This problem is mainly solved from two aspects,we need to strengthen the system's data structure and algorithm efficiency and performance,also need to make use of third-party formation(library)to help prompt the concurrency of the system.By compared with the traditional multi-thread model,the service platform based on event-driven model has unparalleled advantages in memory utilization,response speed and programming difficulty,which can significantly increase the concurrency of system application.Based on the Node.js technology,this paper discusses the technology of cache,distributed storage of files and system load balancing,aiming at solving the problem of high speed and stability of the system under massive access.Finally,through the high concurrent test,the feasible is proved.
