Abstract:

   This document specifies properties and 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.

   for publication as an RFC.  This draft should be held for publication
   until the queue protection RFC can be referenced.]
