AAA and Mobile IPv6

Franck Le

AAA WG - IETF55

Why Diameter support for Mobile IPv6?

• Mobile IPv6 is a routing protocol and does not deal with issues related to roaming between administrative domains, e.g.

• authorization and authentication of mobile nodes• accounting• establishment of SAs needed for roaming mobile

nodes

• In order to deploy Mobile IPv6 on a large scale, support of inter-domain roaming is needed

• MIPv6 does not have the equivalent of an FA (MIPv4) and as a result does not define any mechanism by which the visited domain can authenticate/authorize access to the local resources and handle accounting tasks

• Diameter support for MIPv4 has been worked on in this WG for above reasons

I-Ds discussing AAA for MIPv6

• Mobile IPv6 Authentication, Authorization, and Accounting Requirements

• Diameter Mobile IPv6 Application

Mobile IPv6 Authentication, Authorization, and Accounting

Requirements I-D

• Motivation why Diameter support for Mobile IPv6 is required and needs to be developed

• Analysis and updates to the requirements expressed in RFC 2977 “Mobile IP Authentication, Authorization, and Accounting Requirements “

• RFC 2977 specified requirements for both Mobile IPv4 and Mobile IPv6. This internet draft focuses on Mobile IPv6.

Diameter Mobile IPv6 Application I-D

• Based on the requirements, this I-D proposes Diameter Application for Mobile IPv6

• New Diameter application to support:• Mobile node authentication and authorization• Dynamic home agent assignment• Dynamic home address assignment• Key distribution

Next steps

• Request AAA WG to begin work that deals with Diameter for Mobile IPv6 now

• Requirements I-D and Diameter for MIPv6 App I-D be the starting point

• Chair/WG action:

• Above drafts be considered as WG I-Ds and WG charter include completion milestones for the same
