从实际出发,在简单分析理论上的互连方案后,提出面向应用的互连概念,讨论现有的异步通信、X.25网(如CHINAPAC)与TCP/IP网(如Internet)的互连技术,比较各种方案的优缺点。
From a practical point of view, after simply analyzing the theoretical interconnection scheme, the concept of application-oriented interconnection is proposed and the existing asynchronous communication is discussed. 25 network (such as CHINAPAC) and TCP / IP network (such as Internet) interconnect technology, compare the advantages and disadvantages of various programs.
