All,

Thomas and I just posted a draft-00 of the NQB PHB definition.  This draft addresses most (but not all!) of the mailing list comments.  

Of note, this version has been heavily restructured from the adopted draft in order to better align with expectations and requirement for a PHB spec.  Also, it includes a temporary "Open Points" section that captures the known open discussion points.  

Thanks again to all of the reviewers of the individual draft for the comments and suggestions.  I hope that we've not forgotten to address any of them.  Please gently remind us if we have!

Best Regards,
Greg

    Abstract:
       This document specifies properties and characteristics of a Non-
       Queue-Building Per-Hop Behavior (NQB PHB).  The purpose of this NQB
       PHB is to provide a separate queue that enables low latency and, when
       possible, low loss for application-limited traffic flows that would
       ordinarily share a queue with capacity-seeking traffic.  The PHB
       provides low latency and, when possible, low loss without
       prioritization and without rate policing, making it suitable for
       environments where the use of either these features may be
       restricted.  The NQB PHB has been developed primarily for use by
       access network segments, where queuing delays and queuing loss caused
       by Queue-Building protocols are manifested, but its use is not
       limited to such segments.  In particular, applications to cable
       broadband links and mobile network radio and core segments are
       discussed.  This document defines a standard Differentiated Services
       Code Point (DSCP) to identify Non-Queue-Building flows.
