Abstract
This document presents a set of requirements for Traffic Engineering
over Multiprotocol Label Switching (MPLS). It identifies the
functional capabilities required to implement policies that
facilitate efficient and reliable network operations in an MPLS
domain. These capabilities can be used to optimize the utilization of
network resources and to enhance traffic oriented performance
characteristics.
