Abstract: Drawbacks and limitations of previous virtual local area network (VLAN) implementation methods in Ethernet environment are analyzed. Then a kind of VLAN administration strategy based on service is proposed to set up the virtual local area network (VASS) administration strategy system architecture, i.e., a fairly integrated VLAN architecture based on service. A simulation and UDP video transmission experiment were conducted and the results show that VASS can properly control broadcast traffic and decrease local area network route traffic flow to a great extent so as to improve network system's ability to withstand broadcasting storm. The distribution of network resource adaptable to the model is more flexible and effective than before with the network service efficiency improved.
