基于IEEE802.1Q帧标记的VLAN实现原理

Study on the principle of realizing the VLAN based on IEEE 802.1Q frame tag

IEEE 802.1Q标准通过标准化的帧标记来实现虚拟局域网。对802.1Q的帧标记格式,VLAN的实现机制从入口过程、转发过程、出口过程进行了深入的分析研究,并结合实例给予了说明。

The standard of IEEE 802.1Q realizes the VLAN by using the standard frame tag. The paper studies the format of 802.1Q, the mechanism of realizing the VLAN from ingress process, forward process, egress process, and gives explanations by example.
