摘要：Recently, with the advent HTML5, the performance of Web service has improved. It was difficult to configure the web services using only HTML. However, communication between the client and the server is now possible because of HTML5. HTML5 was designed to be platform independent, and can be used on an increasing number of mobile devices for creating both mobile websites and mobile applications. It is frequently cited as the primary solution for enabling effective cross-platform deployment onto various smart devices. HTML5 has many new features. One of the most powerful features is the WebSocket. Updated HTML5 specifications for web sockets, web browsers, and web servers allow sending and receiving data in real time, via an always-on TCP connection. The crucial differences between pre-HTML5 communication methods and HTML5 WebSocket are located in the new HTML5 protocol. WebSocket protocol uses HTTP to establish a connection, but the subsequent communication is performed by the WebSocket reader protocol. In addition, the feature header is very small, resulting in reduced communication overhead. The WebSocket aims to solve the problems of the conventional communication method, though it has several restrictions. Therefore, in this study, experiments were conducted to measure the performance analysis of WebSocket. We conclude by presenting the direction of future research in this field.
