Summary:A technology is disclosed for reducing the number of encapsulations required when MAP forwards a packet to a mobile node which is layered within mobile networks, with mobile networks nested and multiple mobile routers chained behind MAP (Mobility Anchor Point). When a node 420 with Address A wants to send a packet to a node 450 with Address D, the node with Address A inserts a list of immediate addresses into the packet. The list includes a node 430 with Address B and a node 440 with Address C, and the destination address of the packet is set to a next hop destination Address B. The node with Address B receives the packet and swaps the destination address with Address C described in the list of immediate addresses. Similarly, the node with Address C processes the same swapping process, and then the packet reaches the node with Address D.
