  19. Wi-Fi & WiMax CERNET'2004

  20. Mobile IP - MIP • Solving the mobility issue in IP layer • Activities in IETF, RFC3775 • Mobile IP allows a mobile host to move about without changing its permanentIP address • Each mobile host has a home agent on its home network • Mobile host establishes a care-of address when it's away from home CERNET'2004

  21. IP header IP header data data IP-in-IP tunnel • Forwarded MIP packet encapsulated in another IP packet • New IP packet: • Destination = care-of-address • Source = address of home agent • Protocol ID = IP-in-IP IP header CERNET'2004

  22. Satellite Local area High end 本地范围 Wide Area Low speed moving High speed moving Roaming among Heterogeneous network • Seamless mobility across diverse overlay networks • “vertical” hand-offs • software “agents” + hardware support for heterogeneity management CERNET'2004
