Subject:  Flow mobility feature being specified for Proxy Mobile IPv6 (RFC5213) in the NETEXT WG

Dear Balazs, Andy and, Hong,

We would like to inform you about the work being done on extending Proxy Mobile IPv6 (RFC5213) to support flow mobility within the 
NETEXT WG in the IETF. The NETEXT  WG charter was revised and approved in February 2010 with this new work. One of the current 
goals and milestones of the group is:

Oct 2010 - Initial WG document(s) on Proxy Mobile IPv6 Extensions to Support Flow Mobility and Inter-access Handovers on a Logical 
Interface over Multiple Physical Interfaces

Full scope of the effort and more details are described in http://www.ietf.org/dyn/wg/charter/netext-charter.

Please consider this as an informative update for SA2 on the developments in NETEXT WG in the IETF.

Best Regards,

IETF NETEXT WG chairs                       IETF Internet Area Director
