Abstract
LAN emulation in a moving network environment is disclosed. An emulated LAN encompassing a number of moving networks is formed by means of a set of layer 2 tunnels that interconnect a home agent with mobile routers in the moving networks. The home agent and the mobile routers are arranged to perform layer 2 forwarding over the layer 2 tunnels in order to form the emulated LAN. The layer 2 tunnels can be established in a number of alternative ways. The moving networks that are part of the emulated LAN may move, i.e. change their points of attachment to the network infrastructure, in a dynamic fashion without disrupting the function of the emulated LAN.
