Title : MPLS Inter-AS Traffic Engineering requirements

This document discusses Service Providers requirements for the
support of inter-AS MPLS Traffic Engineering (MPLS TE). The main
objectives of this document are to present a set of requirements
and applicable deployment cases which would result in some general
guidelines in the definition, selection and specification
development for a technical solution meeting these requirements
that will be covered in a separate draft.
The document will first discuss issues in current BGP-based inter-
AS traffic engineering practices in supporting QoS-enabled paths
across multi-ASes, hence arrive at the requirement for extending
the current MPLS TE mechanism beyond BGP AS boundaries. A set of
application scenarios will also be presented as potential
deployment cases of inter-AS MPLS TE. A list of detailed
requirements along with the evaluation criteria for a technical
solution is also provided.
Discussions presented here will cover inter-AS TE in both IPv4 and
VPNv4 addressing planes. Information regarding VPNv4 addressing
plane over BGP/MPLS VPNs is detailed in [PPVPN-RFC2547bis].

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
