Abstract:
The Path Computation Element (PCE) provides path computation
functions in support of traffic engineering in Multiprotocol Label
Switching (MPLS) and Generalized MPLS (GMPLS) networks.
A link or node failure can significantly impact network services in
large-scale networks. Therefore it is important to ensure the
survivability of large scale networks which consist of various
connections provided over multiple interconnected networks with
varying technologies.
This document examines the applicability of the PCE architecture,
protocols, and procedures for computing protection paths and
restoration services, for single and multi-domain networks.
This document also explains the mechanism of Fast Re-Route (FRR)
where a point of local repair (PLR) needs to find the appropriate
merge point (MP) to do bypass path computation using PCE.
