The Mobility for IPv4 (mip4) 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 IPv4 (mip4) ========================== Current Status: Active Working Group Chair(s): Peter McCann <mccap@lucent.com> Henrik Levkowetz <henrik@levkowetz.com> Internet Area Director(s): Mark Townsley <townsley@cisco.com> Margaret Wasserman <margaret@thingmagic.com> Internet Area Advisor: Margaret Wasserman <margaret@thingmagic.com> Mailing Lists: General Discussion: mip4@ietf.org To Subscribe: mip4-request@ietf.org In Body: subscribe Archive: http://www.ietf.org/mail-archive/web/mip4/index.html Description of Working Group: IP mobility support for IPv4 nodes (hosts and routers) is specified in RFC3344. RFC 3344 mobility allows a node to continue using its "permanent" home address as it moves around the internet. The Mobile IP protocols support transparency above the IP layer, including maintenance of active TCP connections and UDP port bindings. Besides the basic Mobile IPv4 (MIPv4) protocols, several other drafts deal with concerns such as optimization, security, extensions, AAA support, and deployment issues. Mobile IPv4 is currently being deployed on a wide basis (e.g., in cdma2000 networks). The scope of the deployment is on a fairly large scale and accordingly, the MIP4 WG will focus on deployment issues and on addressing known deficiencies and shortcomings in the protocol that have come up as a result of deployment experience. Specifically, the working group will complete the work items to facilitate interactions with AAA environments, interactions with enterprise environments when Mobile IPv4 is used therein, and updating existing protocol specifications in accordance with deployment needs and advancing those protocols that are on the standards track. Work expected to be done by the MIP4 WG as proposed by this charter is as follows: 1. MIPv4 has been a proposed standard for several years. It has been adopted by other standard development organizations and has been deployed commercially. One of the next steps for the WG is to advance the protocol to draft standard status. As part of advancing base Mobile IP specs to DS, the Mobile IPv4 NAI RFC (2794) will be revised to reflect implementation experience. 2. A mechanism for home agent assignment at the time of mobile-ip registration, rather than preconfigured for the mobile node, has been proposed. The WG will take on the task of completing this. The ability to switch the home agent assigned to a mobile node while registered will also be considered as part of this task. 3. Work items that are pending from the previous Mobile IP WG, which will be completed by the MIP4 WG, are: - RFC3012bis (Challenge-response mechanism) - low-latency handover draft to experimental status - completion of the MIB for the revised base Mobile IP specification (2006bis) - regional registration draft. 4. The MIP4 WG will also complete the work on Mobile IPv4 interactions in VPN scenarios. This work will involve identifying the requirements and a solution development for Mobile IPv4 operation in the presence of IPsec VPNs. 5. Some issues have been raised with respect to RFC3519. These will be identified and addressed as appropriate, through errata, revision of RFC 3519, and/or supplemental documents as needed. Other potential work items may be identified in the future but will require an appropriate re-charter.
