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
1.
2.

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

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


Addresses Inter Access Router (AR) handoffs


No new MH, MO required
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:
