Abstract:
   This document specifies properties and characteristics of a Non-
   Queue-Building Per-Hop Behavior (NQB PHB).  The purpose of this NQB
   PHB is to provide a separate queue that enables low latency and, when
   possible, low loss for application-limited traffic flows that would
   ordinarily share a queue with capacity-seeking traffic.  This PHB is
   implemented without prioritization and without rate policing, making
   it suitable for environments where the use of either these features
   may be 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 and mobile network radio and core segments are
   discussed.  This document defines a standard Differentiated Services
   Code Point (DSCP) to identify Non-Queue-Building flows.
