Dapeng, Below is the charter text that was submitted to the next IESG. Does it cover all your concerns? - JOuni Distributed Mobility Management (DMM) ------------------------------------- Charter Current Status: Active Chairs: Julien Laganier <julien.ietf@gmail.com> Jouni Korhonen <jouni.nospam@gmail.com> Internet Area Directors: Ralph Droms <rdroms.ietf@gmail.com> Jari Arkko <jari.arkko@piuha.net> Internet Area Advisor: Jari Arkko <jari.arkko@piuha.net> Mailing Lists: General Discussion: mext@ietf.org To Subscribe: https://www.ietf.org/mailman/listinfo/mext Archive: http://www.ietf.org/mail-archive/web/mext Description of Working Group: The Distributed Mobility Management (DMM) working group specifies IP mobility, access network and routing solutions, which allow for setting up IP networks so that traffic is distributed in an optimal way and does not rely on centrally deployed anchors to manage IP mobility sessions. The distributed mobility management solutions aim for transparency above the IP layer, including maintenance of active transport level sessions as mobile hosts or entire mobile networks change their point of attachment to the Internet. The protocol solutions should be based on existing IP mobility protocols, either host- or network-based, such as Mobile IPv6 [RFC6275, 5555], Proxy Mobile IPv6 [RFC5213, 5844] and NEMO [RFC3963]. Solutions may also focus specifically on managing the use of care-of versus home addresses in an efficient manner for different types of communications. Although the maintenance of stable home address(es) and/or prefix(es) and upper level sessions is a desirable goal when mobile hosts/routers change their point of attachment to the Internet, it is not a strict requirement. Mobile hosts/routers should not assume that IP addressing including home address(es) and/or home network prefix(es) remain the same throughout the entire upper level session lifetime, or that support for mobility functions is provided on the network side in all conditions. The distributed mobility management solutions primarily target IPv6 Deployment and should not be tailored specifically to support IPv4, in particular in situations where private IPv4 addresses and/or NATs are used. At least IPv6 is assumed to be present in both the mobile host/router and the access networks. Independent of the distributed mobility management solution, backward compatibility must be maintained. If the network or the mobile host/router do not support the distributed mobility management enabling protocol, nothing should break. Work items related to the distributed mobility management include: o Solution Requirements: Define precisely the problem of distributed mobility management and identity the requirements for a distributed mobility management solution. o Best practices: Document best practices for the deployment of existing mobility protocols in a distributed mobility management environment. o Gap Analysis and extensions: identify the limitations in the best current practices with respect to providing the expected functionality. o If limitations are identified as part of the above deliverable, specify extensions to existing protocols that removes these limitations within a distributed mobility management environment. Goals and Milestones: Aug 2012 - Submit I-D 'Solution Requirements' as a working group document. To be Informational RFC. Aug 2012 - Submit I-D 'Best practices and Gap Analysis' as a working group document. To be Informational RFC. Nov 2012 - Evaluate the need for additional working group document(s) for extensions to fill the identified gaps. Jan 2013 - Submit I-D 'Solution Requirements' to the IESG for consideration as an Informational RFC. Jan 2013 - Submit I-D 'Best practices ' to the IESG forvconsideration as an Informational RFC. Mar 2013 - Submit I-D 'Gap Analysis' to the IESG for consideration as an Informational RFC. Mar 2013 - Evaluate the need for further work based on the identified gaps and revise the milestones and/or the charter of the group.
