This document specifies properties and characteristics of a Lower
Effort (LE) per-hop behavior (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, best-effort traffic has precedence over LE
traffic and may preempt it. 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 DSCP value for the LE PHB.
