Research and implementation of VLAN based on service

Network resource is opened for every user in LAN. Considering administration and security, we must restrict them to some degree. Whatever the rank of LAN member is, most of them should be free of route when access to network. Virtual local area network, being a new technique to settle broadcast containment and network security, has already become an important strategy in LAN solution. In this paper, we introduced some kinds of VLAN implementation methods and their main drawbacks in Ethernet environment. On the basis of them, we proposed a new flexible VLAN administration strategy based on service and we set up VASS architecture, a fair integrated VLAN architecture based on service.
