Re: [tsvwg] I-D Action: draft-ietf-tsvwg-nqb-06.txt

Hi all,

This update to the NQB draft includes the following changes:

- Recommends DSCPs 5 & 45 based on the analysis presented by Ana Custura at the last IETF
- Clarifies what the PHB provides, in the abstract & intro
- A more concrete description of NQB behavioral characteristics (including a rule-of-thumb value of 1 Mbps maximum burst rate)
- Moved the text on DSCP re-marking pathologies to an Appendix
- Further restructuring of the WiFi section
- Security section mentions default WiFi configuration
- Moved several references to Normative
- Multiple other editorial fixes

Many of these changes were spurred by off list comments received from David Black, Stuart Cheshire and Bob Briscoe (thanks!).

            Title           : A Non-Queue-Building Per-Hop Behavior (NQB PHB) for Differentiated Services

    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 smooth, low-data-
       rate, application-limited traffic flows, which would ordinarily share
       a queue with bursty and capacity-seeking traffic, to avoid the
       latency, latency variation and loss caused by such traffic.  This PHB
       is implemented 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, Wi-Fi links, and mobile network radio and core
       segments are discussed.  This document recommends a specific
       Differentiated Services Code Point (DSCP) to identify Non-Queue-
       Building flows.
