Re: [tsvwg] I-D Action: draft-ietf-tsvwg-nqb-22.txt

All,

A short while ago, I uploaded a new version of the NQB PHB draft.  This version addresses the long list of comments (many editorial, but also a few technical) provided by Bob Briscoe (https://mailarchive.ietf.org/arch/msg/tsvwg/XPehj4puGc4Yo2EK2NrKfW5FcHI/)  

At this point, the authors believe that the document is ready for a second WGLC.

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

Abstract:


This document specifies characteristics of a Non-Queue-Building Per-
Hop Behavior (NQB PHB). The NQB PHB provides a shallow-buffered,
best-effort service as a complement to a Default deep-buffered best-
effort service for Internet services. The purpose of this NQB PHB is
to provide a separate queue that enables smooth (i.e. non-bursty),
low-data-rate, application-limited traffic microflows, 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 can be implemented
without rate policing, making it suitable for environments where the
use of these features is 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 microflows.


[NOTE (to be removed by RFC-Editor): This document references an ISE
submission draft (I-D.briscoe-docsis-q-protection) that is approved
for publication as an RFC. This draft should be held for publication
until the queue protection RFC can be referenced.]
