Mobility for IPv6 (mip6) ------------------------ Charter Last Modified: 2007-06-15 Current Status: Active Working Group Chair(s): Basavaraj Patil Gopal Dommety Internet Area Director(s): Jari Arkko Mark Townsley Internet Area Advisor: Jari Arkko Mailing Lists: General Discussion:mip6@ietf.org To Subscribe: https://www.ietf.org/mailman/listinfo/mip6 Archive: http://www.ietf.org/mail-archive/web/mip6/index.html Description of Working Group: Mobile IPv6 (MIP6) specifies routing support which permits an IPv6 host to continue using its home address as it moves around the Internet, enabling continuity of sessions. Mobile IPv6 supports transparency above the IP layer, including maintenance of active transport level sessions. The base specifications for Mobile IPv6 consist of: o RFC 3775 o RFC 3776 The primary goal of the MIP6 working group will be to enhance base IPv6 mobility by continuing work on developments that are required for wide-scale deployments. Additionally the working group will ensure that any issues identified by implementation and interoperability experience are addressed, and that the base specifications are maintained. The group will also produce informational documentation, such as design rationale documents or description of specific issues within the protocol. Deployment considerations call for work to reduce per-mobile node configuration and enrollment effort, solutions to enable dual-stack operation, mechanisms to support high-availabity home agents, and ways to employ Mobile IPv6 in the presence of firewalls. Work items related to base specification maintenance include: - Create and maintain an issue list that is generated on the basis of implementation and interoperability experience. Address specific issues with specific updates or revisions of the base specification. One specific area of concern that should be analyzed and addressed relates to multilink subnets. This work item relates only to corrections and clarifications. The working group shall not revisit design decisions or change the protocol. - Update RFC 3776 to specify the usage of IKEv2 for the establishment of the IPsec SA between the MN and HA. This work also provides a way for a mobile node to change its home address or employ multiple home addresses as needed. - Update the IANA considerations of RFC 3775 to allow extensions for experimental purposes as well passing of optional vendor-specific information. Work items related to large scale deployment include: - Bootstrapping Mobile IPv6: A bootstrapping mechanism is intended to be used when the device is turned on the very first time and activates Mobile IPv6, or periodically such as when powering on. The WG should investigate and define the scope before solving the problem. Work on the problem statement and the solutions needed for various deployment scenarios. Work with other WGs such as DHC for defining the options needed for bootstrapping. - Capture the AAA requirements needed for bootstrapping and deployment, and work with the Radext and DiME WGs on the solutions. - A Solution for MIP6 session continuity for dual stack hosts which attach to IPv4 access networks. Additionally provide a mechanism for carrying IPv4 packets via the Home agent for MIP6 capable dual-stack hosts. This work will be done in collaboration with the NEMO WG. - A protocol based solution for enhancing the reliability of home agents and a method to force a host to switch home agents. - A mechanism to force an MN to switch the HA that is currently serving it. This is required in deployments where the HA may need to be taken offline for maintenance. - Work on solutions to deal with firewalls and the problems that firewalls cause as identified in RFC 4487. Work items related to informational documentation include: - Produce a problem statement relating to location privacy and the use of Mobile IPv6. Work with the IRTF MOBOPTS RG on developing the solution. - Produce a design rationale that documents the historical thinking behind the introduction of an alternative security mechanism, the Authentication Protocol (RFC 4285). It should be noted that some of the features that are directly related to Mobile IPv6 are being worked on in the MONAMI6, MIPSHOP, and NEMO working groups. The specific extensions from these groups are out of scope for the MIP6 working group. In particular, all optimizations are out of scope. However, MIP6 may assist these groups when they use features listed above and have requirements on them.
