ABSTRACT:
A virtual network prefix is provided as a dedicated prefix for a mobile node in a domain having a plurality of subnets. The domain includes a layered network that has a quasi-micro mobility network (QMMN) and a pure-micro mobility network (PMMN). The quasi-micro mobility network (QMMN) performs prefix-based routing, and the pure-micro mobility network (PMMN) performs routing using two different routing protocols, that is, prefix-based routing and host-based routing. In each network, processing for changing a route, such as changing cache data or the like, is performed depending on how a terminal moves.
