A MECHANISM TO CREATE PINHOLE FOR EXISTING SESSION IN MIDDLEBOX

摘要

In mobile IP networks, when a mobile node (MN) 101 moves from one cell to another, handover occurs. The result of the handover is that the MN 101 connects to the network through a new access router (AR) 162 . The handover may occur between access routers of the same or different administrative domains. In all cases, the information related to the MN 101 has to be transferred from the old AR 185 to the new AR 162 in order to minimize the effect of the change of access routers.
