Abstract :
E-Learning has been used widely, long-reach, high-speed Ethernet interfaces are not enough to build an Ethernet based metropolitan network; scalability is also important. In Ethernet, scalability is accomplished by using VLANs. QinQ Vlans further improves scalability, and provides a hierarchical approach to Ethernet. This paper discussed double VLAN technology in access network and give a flexible method to support vlan and double VLAN.
