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 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 networks.
This document considers only scalability for point-to-point MPLS-TE.
Point-to-multipoint MPLS-TE is for future study.
