Traffic engineered Multiprotocol Label Switching (MPLS-TE) is
deployed in providers' core networks. As providers plan to grow these
networks, they need to understand whether existing protocols and
implementations can support the network sizes that they are planning.
This document presents an analysis of some of the scaling concerns
for the number of Label Switching Paths (LSPs) in MPLS-TE core
networks, and examines the value of two techniques (LSP hierarchies
and multipoint-to-point LSPs) for improving scaling. The intention is
to motivate the development of appropriate deployment techniques and
protocol extensions to enable the application of MPLS-TE in large
This document only considers the question of achieving scalability
for the support of point-to-point MPLS-TE LSPs. Point-to-multipoint
MPLS-TE LSPs are for future study. This memo provides information
for the Internet community.
This document is a product of the Multiprotocol Label Switching Working Group of the IETF.
