REDIRECTION METHOD, REDIRECTION SYSTEM, MOBILE NODE, HOME AGENT, AND PROXY NODE

摘要

Disclosed is a technique for eliminating wasteful tunneling encapsulation processing when redirecting packets. In said technique, a redirection tunnel (T1) is established between LMA 111 and LMA 112 for redirecting packets from a first connection to a second connection. The first connection uses a first address, for one interface (131) of an MN (130), and is routed through LMA 111 and MAG 121. The second connection uses a second address, for another interface (132) of the MN (130), and is routed through LMA 112 and MAG 122. If MAG 122 knows the first address, packets that are addressed to the first address and were redirected via a tunnel (T) are encapsulated and forwarded to MAG 122 by LMA 112.
