摘要
链接、通信是计算机网络中的基本内容,建立合适的模型进行分析,有助于理论研究与技术创新。描述连接和链接两个概念并给出了它们之间的关系;在定义了逻辑链接后,分别提出有向链接和逻辑链接集合,并形式化定义了数据传输方式。在逻辑链接的基础上,给出了通信状态的定义,并依据有向链接的定义,形式化描述了信息交互的三种基本方式;此外,以层次化的网络通信为背景,定义了对等层通信,并基于映射描述了网络通信的过程。
Link and communication are chief contents of computer network.It is helpful for theoretical research and technological innovation to build an appropriate model for analysis.The paper describes the connection and link concepts as well as the relation between them.Along with the definition of the logical link,also proposed respectively are the directional link and the logical link ensemble,and the data transmission mode is formally defined.Based on the logical link,the definition of communication status is defined;according to the definition of directional link,three basic information interaction approaches are formally described.In addition,with hierarchical network communication as the background,communication between peer layers is defined,and network communication process is described based on mapping.
