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

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.

In the body type:
"FILE /internet-drafts/draft-silverman-tsvwg-mlefphb-03.txt".
NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
