中文说明：点云压缩重建传统网络最初是为数据传输而设计的，是典型的点点通信模式，是为保证数据可靠传输而设计的，所用的传输协议多为点到点的协议。目前，在Internet上产生了许多新的应用，其中不少是高带宽的多媒体应用，譬如网络视频会议 (可视化IP电话会议系统)、网络音频/视频广播、多媒体远程教育、远程会诊，这些应用是典型的点到多点通信模式，如果仍旧采用点到点的通信模式，那么服务器侧需要与每一个客户端建立一条点到点的通信链路，这样所需消耗的带宽就是业务需要带
English Description：
Point cloud compression reconstruction of traditional network was originally designed for the transmission of data is typical of little communication mode, is designed to ensure the reliability of data transmission, the transmission protocol for point-to-point protocol. At present, many new applications on the Internet come into being, and many of them are high bandwidth multimedia applications, such as network video conference (visual IP telephone conference system, network audio / video broadcast, multimedia remote education, remote consultation, these applications are typical of point to multipoint communication mode, if still uses the point-to-point communication mode, then the server side need to establish a point-to-point communication link with each client, so the consumption of bandwidth is the business need to take
