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.]
