Re: [Dime] Topic 2 of draft-ietf-dime-congestion-flow-attributes-00 - Use Cases

["Hirschman, Brent B [CTO]" <[e-mail]>]

I am sure everyone is starting to prepare for Toronto.  I would please request any comments on our draft soon so that I can prepare any special coverage of these topics in our discussion at the Toronto meeting.

Thanks,

Our request for comments on this draft issue has not had any responses yet.  Please take a look at this straightforward, 6 page draft and provide comments.
I know the overload work is of high importance to the working group.  We feel this draft is complete and need everyone's quick review to capture any areas that need refinement.  Your assistance is appreciated.

Subject: [Dime] Topic 2 of draft-ietf-dime-congestion-flow-attributes-00 - Use Cases

At IETF 89 in London, during the discussion of the draft-ietf-dime-congestion-flow-attributes-00.txt, Two areas were requested to be investigated further.  We will be addressing them in separate email threads to keep the discussion focused on each topic.  This is Topic 2:

Second, we were requested to investigate providing example use cases of ECN.  RFC5777 already provides a set of use cases for reporting and ECN is just one of many such reporting parameters such as byte count.  Adding a paragraph of text such as the following may add some information but the authors feel little incremental information is needed because of the work already in RFC 5777.
"Diameter nodes along the bearer path can implement filters to collect accounting and policy control information based on these congestion parameters similar to byte count information. These filters on flows and overall node congestion for these AVPs can report a measure of quality of byte counts to collection points in the network where decisions can be made to mitigate or mediate any congestion conditions for accounting or real time policy control.  These AVPs provide supplemental information as described in the use cases discussed in RFC5777."

Thus, the authors are proposing no modification to the working group draft at this time.  Comments are welcome.
