point-to-point data link meaning in English

定点数据传输线

At the beginning , this paper has some brief dissertation on the basic principle of the dsl and the multimedia data compression , the key technique of sdsl , the transport protocols , and the data transfer system structure based on the twisted - pair . then it gives an analysis of the point - to - point data link protocol ( ppp ) and the real - time transmission protocol in detail , which provide the side - to - side transmission service for audio frequency and video frequency data , and so on based on the these , we developed a multimedia sdsl modem system used to transfer data and phonetic
本文首先对dsl系统和多媒体数据压缩技术的基本原理、 sdsl的关键技术、传输协议以及基于双绞线的数据传输系统的结构进行了简要的论述，并详细分析了点到点的数据链路协议( ppp协议)以及实时传输协议，其为音频、视频等实时数据提供端到端的传送服务。可以向接收端传送恢复实时信号必需的定时和顺序信息，并向收发双方和网络运营者提供qos监测手段。
