Research and implementation of campus information push system based on WebSocket

WebSocket is a TCP-based protocol, providing full-duplex communication channels over a single TCP connection. In recent years, more and more developers choose to use it to develop applications. This paper discusses the traditional real-time Web communication schemes, and analyzes the advantages of WebSocket. Based on the deep study of WebSocket, a real-time campus information push solution based on WebSocket and node.js is proposed. This paper expatiates the overall structure of the scheme, designs and realizes the functions of each module, and the functional testing results show that the scheme is feasible.
