[ppml] question on 2006-2 v6 internal microallocation

[Azinger, Marla]

If Jason's response is the fact we are facing.  It would be good to add some lines into the proposal stating that the intent of this proposal is to be used by those facing these contstraints.  I say this only because I believe it is necessary to point out to people why they would or would not qualify for this type of allocation should this proposal pass.  I read the proposal as it is currently, and this doesnt seem to be clear enough to me.

Thank you

Not all vendors currently support this functionality.  Cisco only supports
this functionality in 12.2 T code.  It will take some time for this
functionality to show up in code that is useful to large service
providers. 

I am also in the process of working with Cisco on a draft RFC to
encourage all vendors to support this functionality.

Large scale ISPs require hardware based packet forwarding to due to the
high pps requirements in some cases as high as 6Mpps.  Currently not all
hardware deployed in all large ISPs has the capability to do line rate
packet filtering on all ingress interfaces.
