time delay switch

A tree is created and maintained by the switch for every VLAN according to the mark affiliated in BPDU. It can cut down the delay from the block state to transmitting state obviously and improve the real-time characteristic in the Ethernet.

在BPDU中加入标示性能的标志，交换机根据这个标志为每个VLAN生成、维护一个稳定的树结构，使交换机端口由阻止状态到转发状态的延迟明显缩短，提高了网络的实时特性。
