Route optimization defines extensions to Mobile IP Registration Requests that allow datagrams in flight when a mobile node moves, and datagrams sent based on an out-of-date cached binding, to be forwarded directly to the mobile node's new binding. These extensions for smooth handoff require a registration key to be established between the mobile node and foreign agent. This document defines additional extensions to the registration requests to allow for the establishment of single-use registration keys between a mobile node and foreign agent.
