摘要
TR-101(Technical Report)是一种非常重要的系统架构标准,它指出了将基于ATM(Asynchronous Transfer Mode)的聚合网络过渡到一种新的基于以太网的聚合网络。主要介绍了VLAN存在的架构体系、接入点处的转发机制和数据流在VLAN端口的传输,对提高网络安全性、数据隔离、减少网络拥堵和增强设备间兼容性起到指引作用。
TR-101 is a very important standard of system architecture. It has specified a network based on ATM aggregation migrate to a new network based on Ethernet aggregation. In this article, the existed system architecture of VLAN ,forwarding mechanisms of access node and data traffics transmis- sion in VLAN port are mainly introduced, and it plays a role of improving network security, data isolation, reducing network congestion and strengthening compatibility between devices.
