   Resource sharing in a network means two or more Label Switched Paths
   (LSPs) use common pieces of resource along their paths. This can
   help save network resources and is 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 responsible for path computation
   with such requirement.

   Existing extensions to the Path Computation Element Protocol (PCEP)
   allow one path computation request for an LSP to be associated with
   other (existing) LSPs through the use of the PCEP Association

   This document extends PCEP in order to support resource-sharing-
   based path computation as another use of the Association Object to
   enable better efficiency in the computation and in the resultant
   paths and network resource usage.
