摘要
目前很多单位网络设备处于百兆千兆设备共存的情况,存在着百兆、千兆设备互联时的一些通信问题。为了理解网络通信的基本原理,从OSI的7层结构和IEEE802协议入手,研究分析百兆、千兆以太网的数据链路层和物理层的结构体系,重点对百兆、千兆以太网的MAC层和物理层通信规则作了对比和详细分析介绍,并在遇到网络通信障碍时,提出应该如何解决问题的方向。
At present, some problems exist in network devices of many units such as 100M and 1000M devices coexistence and communication during interworking between them. In order to understand the basic principles of network communication, based on the OSI seven layers architecture and IEEE802 protocol, this paper studies and analyzes the architecture of datalink layer and physical layer of 100M and 1000M Ethernet, emphasisly compares, analyzes and introduces the communication rules of MAC layer and physical layer of 100M and 1000M Ethernet in detail, and proposes the solution direction when network communication barrier occurs.
