Title: Multi-Level Expedited Forwarding Per Hop Behavior (MLEF PHB)
State: Active

Some networks require certain packet flows to be transported with
preferential treatment over others of the same type (e.g., voice or video).
This document defines a new PHB (Per Hop Behavior), the Multi-Level
Expedited Forwarding (MLEF) PHB, which is a minor extension to EF defined
in RFC 3246. RFC 3246 defines the Expedited Forwarding PHB for applications
requiring low latency, but with a single DSCP and treatment per queue.
Although EF suggests that packet discard should be used to achieve this
behavior, it does not define an algorithm for packet discard. This document
extends that concept and defines a PHB with multiple discard treatments for
packet flows for applications requiring low latency and multiple priority
levels.
