Hi Folks,

First off, thanks to those that read this draft and provided feedback; the co-authors are working on some key revisions and hope to submit individual draft version 1 in mid-April.

One key point that Al made was that the work needed refinement to not only address traffic management verification testing, but to extend into the core scope of BMWG which includes capacity benchmarking, etc.

Our plan to accomplish this is summarized below and any feedback before we make the revisions will be appreciated.

Currently the draft is divided into several sections, each a specific traffic management function:

*        Buffer / Queue testing

*        Policing tests

*        Shaping tests

*        Congestion Management tests

Each individual test provides the test method and metrics that need to be measured in order to properly compare different vendor's performance.

What we propose to add is a scalability test to each individual section, which tests each traffic management function to the rated limits; i.e. if each port can perform shaping at egress simultaneously, then the shaping  scalability test would provide the method to conduct that test

Scalability testing  of a combination of traffic management functions would be a daunting task (i.e. hierarchical QoS policies) and would be outside the scope of this work.  The draft may touch on the subject with general guidelines, but complex QoS policies would be deferred to potential follow-on drafts.

Thanks in advance for any feedback on this proposed alignment to BMWG charter.
