This document specifies properties and characteristics of a Lower-
Effort Per-Hop Behavior (LE PHB). The primary objective of this LE
PHB is to protect Best-Effort (BE) traffic (packets forwarded with
the default PHB) from LE traffic in congestion situations, i.e., when
resources become scarce, BE traffic has precedence over LE traffic
and may preempt it. Alternatively, packets forwarded by the LE PHB
can be associated with a scavenger service class, i.e., they scavenge
otherwise-unused resources only. There are numerous uses for this
PHB, e.g., for background traffic of low precedence, such as bulk
data transfers with low priority in time, non-time-critical backups,
larger software updates, web search engines while gathering
information from web servers and so on. This document recommends a
standard Differentiated Services Code Point (DSCP) value for the LE
PHB.
This specification obsoletes RFC 3662 and updates the DSCP
recommended in RFCs 4594 and 8325 to use the DSCP assigned in this
specification.
This document is a product of the Transport Area Working Group Working Group of
the IETF.
This is now a Proposed Standard.
