IP Routing for Wireless/Mobile Hosts (mobileip) ----------------------------------------------- Charter Last Modified: 01-Nov-01 Current Status: Active Working Group Chair(s): Phil Roberts Basavaraj Patil Internet Area Director(s): Thomas Narten Erik Nordmark Internet Area Advisor: Thomas Narten Mailing Lists: General Discussion:mobile-ip@sunroof.eng.sun.com To Subscribe: mobile-ip-request@sunroof.eng.sun.com In Body: (un)subscribe Archive: http://playground.sun.com/mobile-ip/ Description of Working Group: The Mobile IP Working Group has developed routing support to permit IP nodes (hosts and routers) using either IPv4 or IPv6 to seamlessly "roam" among IP subnetworks and media types. The Mobile IP method supports transparency above the IP layer, including the maintenance of active TCP connections and UDP port bindings. Where this level of transparency is not required, solutions such as DHCP and dynamic DNS updates may be adequate and techniques such as Mobile IP not needed. The WG moving forward will focus on deployment issues in Mobile IP and provide appropriate protocol solutions to address known deficiencies and shortcomings. For example, the wireless/cellular industry is considering using Mobile IP as one technique for IP mobility for wireless data. The working group will endeavor to gain an understanding of data service in cellular systems such as GPRS, UMTS, CDMA2000, and interact with other standards bodies that are trying to adopt and deploy Mobile IP WG protocols in these contexts. In order to provide a complete solution and a set of protocols that can be used as a roadmap for widespread deployment, the following work needs to be accomplished by this WG. In the near term, the WG needs to work on: - Use of NAIs to identify mobile users/nodes. - Specifying how Mobile IP should use AAA functionality to support inter-domain and intra-domain mobility. - Develop solutions for IPv4 private address spaces for the scenarios needed for deployment. - Documenting any requirements specific to cellular/wireless networks. In the longer term, the WG needs to address: - QoS in the mobile IP environment using diff-serv and/or int-serv/RSVP. - Location Privacy. The Working Group will ensure that solutions proposed for these problem domains are suitable for IPv4 and IPv6 respectively. Goals and Milestones: Done Review and approve the charter, making any changes deemed necessary. Done Post an Internet-Draft documenting the Mobile Hosts protocol. Done Review the charter of the Mobile IP Working Group for additional work required to facilitate non-host mobility. Done Submit the IPv4 Mobile Host Protocol to the IESG as a Proposed Standard. Done Submit the IPv6 Mobile Host Protocol to the IESG as a Proposed Standard. Done Submit Internet-Draft for NAI support in Mobile IP to IESG for consideration as a Proposed Standard. Done Review security framework requirements for Mobile IP. Done Review solutions and submit drafts for mobility in private address spaces. Done Supply AAA requirements for Mobile IP to the AAA Working Group Sep 00 Submit the IPv4 Mobile IP Protocol to the IESG for consideration as a Draft Standard. Oct 00 Review the WG charter and update as needed. Dec 00 Develop an access technology independent method for supporting low latency handover between access points within an administrative domain or across administrative domains. Jul 01 Review QoS in a Mobile IP enabled network. Aug 01 Submit Mobile IPv6 MIB to IESG for consideration as a Proposed Standard.
