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 draft-le-aaa-mipv6-requirements-01.txt Diameter Mobile IPv6 Application draft-le-aaa-diameter-mobileipv6-02.txt

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. requirements-01.txt

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 mobileipv6-02.txt

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
