摘要
为了满足网络循环时间的要求（固定为512bit），不同配置的以太网的直径被限制在一定的范围内，使网络系统的覆盖范围受到很大的限制，要扩大网络系统的覆盖范围，必须使用网络互连设备，根据不同系统的要求，介绍利用网桥、交换器和路由器等网络互连设备实现冲突域分隔，设计较大规模以太网系统的技术和方法．
The ethernet diameter with different configuration is limited to a certain range for the need of network cycling time (512 bits),which greatly limits the area that network covers. This paper introduces the tech nology and the method of designing large ethernet system, which uses the network interconnect devices such as bridge, switch, router to separate collision domain.
