For historical interest, this document captures the EF Design Team's
proposed solution, preferred by the original authors of RFC 2598 but
not adopted by the working group in December 2000.  The original
definition of EF was based on comparison of forwarding on an unloaded
network.  This experimental Delay Bound (DB) PHB requires a bound on
the delay of packets due to other traffic in the network.  At the
Pittsburgh IETF meeting in August 2000, the Differentiated Services
working group faced serious questions regarding RFC 2598 - the group's
standards track definition of the Expedited Forwarding (EF) Per Hop
Behavior (PHB).  An 'EF Design Team' volunteered to develop a
re-expression of RFC 2598, bearing in mind the issues raised in the
DiffServ group.  At the San Diego IETF meeting in December 2000 the
DiffServ working group decided to pursue an alternative re-expression
of the EF PHB.

This document is a product of the Differentiated Services Working
Group of the IETF.
