[tsvwg] Re: I-D Action: draft-ietf-tsvwg-nqb-26.txt

[Greg White <[e-mail]>]

All,

This update includes edits in the Wi-Fi section that are aimed at addressing the WGLC comments raised by David Black.  This was the last remaining item that we had planned to work on as an outcome of the discussion of WGLC comments at IETF 120.  I also took this opportunity to polish a few other sentences in the draft.  At this point I believe that we have closed all open issues.

Thank you to everyone who chimed in with their support for moving to finalize the draft. I know that there are many network operators and application developers who have been waiting for the IETF process to conclude before beginning to turn on NQB support, and I hope we are now very near the time that they can begin that process.

Greg

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, and updates the RFC8325
guidance on mapping Diffserv to IEEE 802.11 for this codepoint.


[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.]
