Abstract
A system, method, and router for routing data packets from a moving network to an associated home network. A data packet originating from a mobile network node in the moving network is routed over any of a number of external accesses accessible from different mobile routers, which advertise different address prefixes to mobile network nodes. A first mobile router advertising a first address prefix receives a data packet with a source address with the first address prefix, and selects an external access for routing that is accessible from a second mobile router advertising a second address prefix. The first mobile router detects that the source address of the packet is different from the second address prefix and provides the packet with a different source address with the second address prefix. The first mobile router then transmits the packet to the second mobile router for transmission to the home network.
