在多个 I/O 端点之间实现多对多的通信。基于 SOCKET 的局域网通信是一种灵活的、易于实现的、低成本的方法。它可以运行在各种使用 TCP/IP 协议作为通讯协议的网络上。而在 SOCKET API 的帮助下，开发基于 SOCKET 的局域网通信软件也是易于实现的-In a number of I/O between the endpoints to achieve many-to-many communication. Based on the SOCKET network communication is a flexible, easy realization, low cost method. It can run on a variety of use TCP/IP protocol as the communication protocol of the network. In SOCKET API, SOCKET development based on local area network communication software is easy to achieve
