Technical Summary
This document provides applicability, use case studies and network
design considerations for the Multiprotocol Label Switching Transport
Profile (MPLS-TP).
In the recent years, MPLS-TP has emerged as the technology of choice
for the new generation of packet transport. Many service providers
(SPs) are working to replace the legacy transport technologies, e.g.
SONET/SDH, TDM, and ATM technologies, with MPLS-TP for packet
transport, in order to achieve higher efficiency, lower operational
cost, while maintaining transport characteristics.
The use cases for MPLS-TP include Metro Ethernet access and
aggregation, Mobile backhaul, and packet optical transport. The
design considerations discussed in this document range from
operational experience; standards compliance; technology maturity;
end-to-end forwarding and OAM consistency; compatibility with
IP/MPLS networks; multi-vendor interoperability; and optimization
vs. simplicity design trade off discussion. The general design
principle is to provide reliable, manageable, and scalable transport
solutions.
Working Group Summary
This document has a strong support in the working group
and has been well reviewed.
The AD review resulted in significant restructuring of the
document and revision of the text. The new document was
taken back to the working group for discussion and a further
last call.
Document Quality
This an informational document, it presents some use-cases
and provides design guidelines, but it is not possible to say that
there are implementations.
The document has had the review that is needed, the working
group last call was brought to the attention of SG15 in
ITU-T.
Personnel
Loa Andersson is the document shepherd.
Adrian Farrel is the responsible AD.
