An authenticated Mobile IPv6 Fast Handover scenario

Abstract

Mobile IPv6 enables a mobile node to keep its connectivity to the Internet when changing its access router. Because of link switching and IP operations, there is a period when the mobile node can not send and receive packets. The Mobile IPv6 Fast Handover protocol shortens the “handover latency”. However, after the handovers, a mobile node must pass the authentication during which it is still unable to communicate with the correspondent node. This document specifies a scenario combining Mobile IPv6 fast handover and authentication procedures. This scenario reduces the comprehensive delay and brings security to fast handovers.
