Context Transfer Using GIST
Univ. Goettingen
The CXTP specification uses basic SCTP as transport for CXTP message exchanges between a mobile node's previous and new access routers. It also relies on a pre-established IPsec ESP transport mode tunnel. This document discusses two alternative approaches based on "persistent" associations using either SCTP streams feature or GIST protocol. While both approaches reduce context transfer latency during handovers, GIST also offers more flexible transport and richer security properties.
