摘要
One of the most powerful virtual LAN (VLAN) features es is the capability to group users into broadcast domains, which ale independent of their locations on the physical network. This paper deals with VLAN services using ATM LAN emulation technology which operates on a client/server model, and focuses on the issues of supporting transparent VLAN services for mobile terminals. A mobile VLAN architecture is proposed to efficiently maintain multiple VLAN broadcast domains over ATM networks even if the topology is changed dynamically due to mobility. This architecture exploits a hypercube over tree (HOT) hierarchical structure, i.e., trees are connected in a hypercube manner, to interconnect different VLANs' servers. To filter. excessive server-to-server traffic, an intelligent flame forwarding algorithm is proposed for the servers. The proposed mobile VLAN system brings a step closer towards facilitating mobility and conforms to existing LAN emulation environment.
