Investigated Issues Operational Issues: Pre-authentication to multiple Candidate Target Networks Tunnel management Ping-pong considerations Authentication state management Packet loss prevention techniques: Buffering, reachability test Authentication in initial network attachment Link-layer security and mobility (see mpa-implementation draft for results) Pre-Authorization techniques: Proactive IP address acquisition (IKEv2,DHCP,stateless autoconf, etc.) Proactive DAD / Address resolution issues Pre-allocation of QoS resources (for both end-to-end and edge network) Co-existence with other mobility management protocols MIPv4 FA-CoA, ProxyMIPv6, FMIPv6 In some case, proactive handover tunnel is terminated at serving AR instead of MN For ProxyMIPv6 + MPA, see draft-taniuchi-netlmm-mpa-proxymipv6-00.txt Multicast mobility |
