MOBILITY REALIZATION METHOD BASED ON LOCATION/IDENTIFIER SEPARATION PROTOCOL (LISP) AND TUNNEL ROUTER

摘要

Disclosed are a mobility realization method based on Location/Identifier Separation Protocol (LISP) and a tunnel router. To solve aforementioned technical problem, the method comprises: after obtaining the routing locator (ORLOC) of an old egress tunnel router(OETR) which a mobile node (MN) attached to before switching, a new egress tunnel router (NETR) establishes a forwarding tunnel with the OETR; the OETR forwards the messages, whose destination end identifier (EID) points to the MN, to the NETR through the forwarding tunnel. The aforementioned method and tunnel router enable the OELR to forward messages accurately even after the MN has switched to the NETR.
