Re: Req#1

Is the following also acceptable:

   REQ1:  Distributed processing



          IP mobility, network access and routing solutions provided by

          DMM MUST enable distributed processing for mobility management

          so that traffic can avoid traversing

          mobility anchors that are in non-optimal routes.

I am trying to write it in simple wording and not getting into a new term such as "off path"

Hello folks,



   REQ1:  Distributed processing



          IP mobility, network access and routing solutions provided by

          DMM MUST enable distributed processing for mobility management

          so that traffic does not need to traverse centrally deployed

          mobility anchors and thereby avoid non-optimal routes.

The real issue is not the "central location of the anchor", but "off-path location of the anchor".

The triangular route is caused by forcing the packets to traverse an anchor node that is not on the direct IP path between the MN and the CN.

See the CNet-Homing proposal. http://www.ietf.org/id/draft-yegin-dmm-cnet-homing-01.txt. We place the anchor in corresponding network, or the ISP serving that network. Therefore, the path going via that anchor does not cause triangulation. Some people may perceive that as locating the anchor in a central location (though this time it's not an "absolute/unchanging" center as implied in the current text).

Therefore I recommend the following revision:


   REQ1:  Distributed processing



          IP mobility, network access and routing solutions provided by

          DMM MUST enable distributed processing for mobility management

          so that traffic is not forced to traverse off-path

          mobility anchors and thereby avoid non-optimal routes.
