Abstract:
Resource sharing in a network means two or more Label Switched Paths
(LSPs) use common piece(s) of resource along their paths. This can
help save network resource and useful in scenarios such as LSP
recovery or when two LSPs do not need to be active at the same time.
A Path Computation Element (PCE) is a centralized entity,
responsible for path computation. Given this feature and its access
to the network resource information and possibly active LSPs
information, it can be used to support resource-sharing-based path
computation with better efficiency.
This document extends the Path Computation Element Protocol (PCEP)
in order to support resource sharing-based path computation.
