Proxy MIP6 IETF67 B. Patil, Gopal D., S. Gundavelli, K. Chowdhury
Why Proxy operation of MIP6? • SDOs like 3GPP2/WMF have shown interest • They are currently incorporating MIP6 in their specs • Operators planning on deploying MIP6 have a strong need for proxy operation • Proxy operation is an incremental feature addition that reuses the investment in the MIP6 infra • Suport for hosts that do not have MIP6 client
Scope of PMIP6 • Extension to MIP6 specification (RFC 3775) enabling proxy operation for IPv6 hosts • i.e host is not involved in the mobility management • Reuse MIP6 signaling and, the Home agent function • Minimal changes to support the security model that the proxy operation necessiates
What PMIP6 is not • A mobility solution for micro mobility • i.e mobility in an access network • Intended to solve the problem of localized mobility management • A solution for mobility across administrative domains
Present status • Two Proxy MIP6 proposals exist • draft-sgundave-mip-pmipv6-00 • draft-chowdhury-netmip6-01 • Interest in Proxy MIP6 as a network based mobility solution has been expressed by other SDOs (although not in any formal manner to the IETF) • Discussion on the ML in MIP6 and NETLMM arguing for standardizing PMIP6
draft-sgundave-mip-pmipv6-00.txt • Summary: • Provides Network based mobility management support for IPv6 hosts. • Leverages Mobile IPv6 Home Agent Infrastructure and the protocol messaging • Minimal changes to the Mobile IPv6 Home Agent • - Supports PER-MN-PREFIX and PER-MN-ADDRESS models. • - Supports Stateless and Statefull address configuration modes • Next Revision: • MN flow identification in the tunnel • Update the document based with any missing details
draft-chowdhury-netmip6-01.txt • Defines IP session setup procedures with PMIP6 • Supports both IPv6 and IPv4 addressing • Reuses MIP6 base protocol (RFC 3775) for mobility management • No new MH, MO required • Addresses Inter Access Router (AR) handoffs • Inter AR signaling with ICMPv6 extensions • Includes HMIP6 consideration • Proxy HMIP6 within the MAP footprint
Question to WG • Given the limited scope of Proxy operation of MIP6 (as discussed) • Should the IETF standardize a PMIP6 solution? • Next steps: • ???
