The Mobility for IP: Performance, Signaling and Handoff Optimization (mipshop) working group in the Internet Area of the IETF has been rechartered. For additional information, please contact the Area Directors or the working group Chairs. +++ Mobility for IP: Performance, Signaling and Handoff Optimization (mipshop) -------------------------------------------------------------------------- Current Status: Active Working Group Chair(s): Gabriel Montenegro <gabriel_montenegro_2000@yahoo.com> Stefano Faccin <stefano.m.faccin@intel.com> Internet Area Director(s): Mark Townsley <townsley@cisco.com> Jari Arkko <jari.arkko@piuha.net> Internet Area Advisor: Jari Arkko <jari.arkko@piuha.net> Mailing Lists: General Discussion: mipshop@ietf.org To Subscribe: mipshop-request@ietf.org In Body: subscribe Archive: http://www.ietf.org/mail-archive/web/mipshop/index.html Description of Working Group: Mobile IPv6 enables IPv6 mobile nodes to continue using a given "home address" in spite of changes in its point of attachment to the network. These changes may cause packet loss, and also represent overhead traffic on the network. The previous MIPSHOP charter directed the group to continue work (started by the Mobile IP Working group) on two technologies to address these issues. Hierarchical Mobile IPv6 (HMIPv6, RFC 4140) reduces the amount and latency of signaling between a MN, its Home Agent and one or more correspondent nodes. Fast Handovers for Mobile IPv6 (FMIPv6, RFC 4068) reduces packet loss by providing fast IP connectivity as soon as the mobile node establishes a new point of attachment at a new link. As part of its previous set of work items, MIPSHOP published these two protocols as experimental RFCs. An information document on how FMIPv6 can operate over IEEE 802.11 was also published as an informational RFC. Further implementation work by the community has increased the understanding of how FMIPv6 behaves or should behave on other link layers, and in general. Similarly, further implementation and experimentation with HMIPv6 has resulted in better understanding of the protocol. Accordingly, MIPSHOP will continue work on HMIPv6 and FMIPv6 in order to prepare their publication as proposed standards. Additionally, the IEEE 802.21 Media Independent Handoff (MIH) working group aims at providing services to assist with handoffs between heterogeneous link-layer technologies, and across IP subnet boundaries. The information exchanges defined by IEEE 802.21 are classified as MI (Media Independent) Event Service (MIES), MI Command Service (MICS), and MI Information Service (MIIS). The MIIS provides topological and location-related information of service networks. The MIES provides timely communications of wireless environment information via the delivery of events originating across the link-layer or farther away. The MICS is an analogous service for commands which can change the state of the wireless link or of a host's point of attachment, potentially triggering further event generation. MIH services can be delivered through link-layer specific solutions and/or through a "layer 3 or above" protocol. MIPSHOP will define the delivery of information for MIH services for this latter case. Notice that this allows the network information to reside anywhere (not necessarily across the link-layer hop), and enables MIH services even in the absence of the corresponding link-layer support. An L2 or L3 based mechanism to identify a valid information server is also required; in particular for L3, we expect that any of the several current L3 discovery mechanisms will be used. A liaison with IEEE 802.21 has been established, and access to the IEEE 802.21 drafts is granted to mipshop members. Interested members need to send a request to the WG chairs in order to obtain a copy of the current IEEE 802.21 draft. There have been several proposals to improve upon the Return Routability procedure defined in MIPv6 (RFC 3775), both in terms of the security of the mechanism as well as with respect to its performance. In particular, discussions within the MOBOPTS Research Group of the IRTF have centered on reducing the round trip times required to complete the procedure, and on increasing the length of time before the procedure needs to be run again. Some proposals are mature enough that they will be taken over by MIPSHOP for standardization. The WG will be very proactive in seeking AD-coordinated security reviews of the drafts developed in the WG. Scope of MIPSHOP: The working group will: 1. Revise the specification of HMIPv6 (RFC 4140) protocol to advance it to Proposed Standard. This implies: * Work on MN-MAP security * Streamline and refine the current HMIPv6 specification. * Document: draft-ietf-mipshop-hmipv6-rev-XX.txt 2. Revise the specification of FMIPv6 protocol (RFC 4068) to advance it to Proposed Standard. * Work on MN-AR (access router) security using both the AAA infrastructure, and keys derived from SeND o Documents: draft-ietf-mipshop-handover-keys-aaa-XX.txt, draft-ietf-mipshop-handover-key-send-XX.txt * Streamline and refine the current FMIPv6 specification (draft-ietf-mipshop-fmipv6-rev-XX.txt) 3. Work on the application of FMIPv6 on two examples link-layers for advancement as Informational RFCs: * IEEE 802.16e (and WiMax), and * 3G CDMA 2K networks * Documents: draft-ietf-mipshop-fh80216e-XX.txt, draft-ietf-mipshop-3gfh-XX.txt 4. Produce a document on improving MIPv6 Return Routability via both Cryptographically Generated Addresses and Credit-based Authorization for advancement as Proposed Standard * Documents: draft-ietf-mipshop-cga-cba-XX.txt 5. Work on areas of mutual interest to IEEE 802.21 and MIPSHOP: * Produce the required protocol enhancements or specifications for IP-based support of Media-Independent Information, Command and Event Services. * Documents: draft-ietf-mipshop-mih-info-elements-XX.txt (information elements), draft-ietf-mipshop-mih-support-XX.txt (transport of 802.21 services over IP, including security aspects) Tackling further work, although possible, requires re-chartering.
