Abstract:
1. A network system, comprising: a plurality of mobility anchors that accommodate a plurality of mobile nodes; an anchor allocation hardware unit that allocates one of said plurality of mobility anchors to each of said mobile nodes, wherein each of said mobility anchors registers a corresponding relationship between a home address assigned to each of said mobile nodes on a home network to which each of said mobile nodes accommodated belongs and a care-of address assigned to each of said mobile nodes on an external network to which each of said mobile nodes connects at its mobility destination, and when each of said mobile nodes is connected to said external network and a packet destined to each of said mobile nodes is received, transfer said packet to each of said mobile nodes based on the corresponding relationship, said anchor allocation hardware unit allocates a same mobility anchor to a first mobile node and a second mobile node, the first mobile node frequently communicates with the second mobile node; and a subscriber information accumulation hardware unit that records the first mobile node ID for uniquely identifying the first mobile node corresponding to the second mobile node ID for uniquely identifying the second mobile node that frequently communicates with the first mobile node, wherein said anchor allocation hardware unit allocates said same mobility anchor to the first mobile node and the second mobile node referring to said subscriber information accumulation hardware unit, and said anchor allocation hardware unit decides whether or not to allocate said same mobility anchor to the first mobile node and the second mobile node, based on amount of communication between the first mobile node and the second mobile node.
