10BASE-T以太网物理介质连接单元的设计仿真

Design and Simulation of 10BASE-T Ethernet Physical Media Connection Unit

以太网技术占据了大量的局域网市场,是目前应用最广泛的网络技术,为实现以太网设备的国产化设计,自主设计以太网各个站点的物理介质连接单元(MAU)至关重要。本文对MAU进行简要描述,研究了10BASE-T的MAU功能的状态机;最后对MAU主要功能进行了仿真测试。结果表明:自主设计的10BASE-T的MAU为研制以太网奠定了基础。

Ethernet technology occupies a large number of LAN market, which is currently the most widely used network technology. In order to achieve the localization of Ethernet equipment design, independent design of each site Ethernet physical connection unit（MAU） is essential. In this paper, the MAU is briefly described, and the state machine of the MAU function of 10 BASE-T is studied. Fi-nally, the MAU main function is simulated. The results show that the self-designed 10 BASE-T MAU lays the foundation for the devel-opment of Ethernet.
