MIP6: Food for thought B. Patil Mobopts @ IETF68 March 22, 07
Background • Mobile IPv6 (RFC 3775) published in June 04 • Not exactly NKOB anymore • Some amount of experience with implementing the protocol has been gained • Deployment experiences would benefit
Route Optimization • MIP6 RO is one of the more salient features • When does RO get triggered? • Type of traffic? • Duration of session? • Other criteria? • Guidelines for when to trigger RO and mechanisms for such would be useful and help deployments
Signaling Compression • The MIP6 signaling messages with various extensions are starting to get bulky • E2E compression, i.e between MN and HA would possibly alleviate this issue • Analysis of compression schemes and applicability in various scenarios is worth studying to improve MIP6 efficiency
Multicast • Multicast in the Mobile IPv6 context has not been completely addressed • Acknowledged shortcoming in the base specification (RFC3775) • Mcast analysis and operation in MIP6 networks with/without RO is very much needed
Handover enhancements • With multi-interface devices/hosts becoming more prevalent, the need for seamless handovers at L3 is even more relevant • Solutions that abstract L2 triggers and enable MIP6 handovers between access types needs to progress faster • Simulations and implementation results needed • Ongoing work based on 802.21 is a good start • Need to expand this to cover generic access types
Host and network based mobility • Co-existence of host and network based mobility approaches in networks would help • Transitive trust and authorization models when the host is not involved need to be better understood • Scenarios and issues related to mobility between networks that manage host mobility vs the host managing its own mobility needed • Impacts to applications/IP sessions in transitioning between mobility types
