At IETF81, the Netext WG discussed the proposal: "IP Traffic Offload
Selector Option for Proxy Mobile IPv6"


   This specification defines a mechanism and a related mobility option
   for carrying IP Offload traffic selectors between a mobile access
   gateway and a local mobility anchor in a Proxy Mobile IPv6 domain.
   Based on the received offload flow selectors from the local mobility
   anchor, a mobile access gateway can enable offload traffic rule on
   the selected IP flows.

Please note that the offloading of traffic from the MAG is limited to
IPv4 flow only using NAT44 functionality.

The general consensus of the room at the IETF81 WG meeting was that
this is a relevant problem and should be solved by the WG. As per the
11 people think we should solve the problem, 4 think we should not.

As per process, the same question is now being asked on the Netext WG
ML before making a decision.


1. Is the solution to offloading specific IPv4 flows from a MAG of
interest to the WG?

Yes   [ ]
No    [ ]

2. Should we adopt as WG I-D:
draft-gundavelli-netext-pmipv6-sipto-option-01.txt which will serve as
the starting point in specifying the solution?

Yes  [ ]
No   [ ]

Please respond to the above questions by August 18, 2011 on the ML.


The slides presented at the meeting are available in the IETF81
proceedings. Minutes have been posted to the ML and are also available
