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 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 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 flows.

   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.]
