  1. Mobility and Multihoming Pasi Eronen and Sanna Liimatainen

  2. Pure Layer 3: Mobile IP • Comparison IPv4 and IPv6 and IKE Mobility Extensions (“easy”) • RFC 3220 IP Mobility Support for IPv4 • http://www.ietf.org/internet-drafts/draft-ietf-mobileip-ipv6-24.txt • Not much material yet available about the last one • Introduction to these and comparison to each other (“easy”)

  3. Pure Layer 4 Topics • SCTP, Stream Control Transmission Protocol (SCTP) • http://www.ietf.org/rfc/rfc3286.txt?number=3286 • http://www.sctp.de/sctp.html • TCP-MH, TCP Multi-Home Options • http://ietfreport.isoc.org/idref/draft-arifumi-tcp-mh/ • DCCP Datagram Congestion Control Protocol (dccp) • http://www.ietf.org/html.charters/dccp-charter.html • http://www.icir.org/kohler/dcp/ • Introduction to these and comparison to each other (“easy”)

  4. Future Layer “3,5” approaches • HIP host identity payload • http://homebase.htt-consult.com/~hip/ • MAST = multiple address service for transport (mast) • http://www.ietf.org/internet-drafts/draft-crocker-mast-proposal-01.txt • LIN6 Location Independent Networking for IPv6 • http://www.lin6.net/ • Introduction to these and comparison to each other (“intermediate”)

  5. Which Layer? • What are the benefits and drawbacks of using layer 2, layer 3, layer 4, and layer 3.5 protocols for mobility? (“hard”) • Two students with different tutors -> different opinions?
