First stepRedundancy and per-CN mobility

• Multiple CoAs registration with a single HoA– Backup purposes

CoA1 CoA2 CoA3

InternetCN1

HoA <->CoA1, CoA2, CoA3

CN2HoA <->CoA1, CoA2, CoA3

CN3HoA <->CoA1, CoA2, CoA3

Second stepFlow mobility

• Flow movement / filtering

Implementation status

• Multiple CoA Registration– WIDE SHISA (FreeBSD/NetBSD)– KDDI Mobile Router– Note that interoperability was confirmed

• Filters for Mobile IP Bindings (NOMAD)– UoB-NOMAD Software (Linux)– Used in Trials of EU IST Project
