The IESG has received a request from the Transport Area Working Group WG (tsvwg) to consider the following document: - 'A Lower Effort Per-Hop Behavior (LE PHB)' <draft-ietf-tsvwg-le-phb-07.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2019-02-12. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract 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. 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 DSCP value for the LE PHB. This specification obsoletes RFC 3662 and updates the DSCP recommended in RFC 4594 and RFC 8325 to use the DSCP assigned in this specification. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-tsvwg-le-phb/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-tsvwg-le-phb/ballot/ No IPR declarations have been submitted directly on this I-D. The document contains these normative downward references. See RFC 3967 for additional information: rfc2475: An Architecture for Differentiated Services (Informational - IETF stream)
