This document introduces a simple mechanism to associate a group of
Label Switched Paths (LSPs) via an extension to the Path Computation
Element Communication Protocol (PCEP) with the purpose of computing
diverse (disjointed) paths for those LSPs. The proposed extension
allows a Path Computation Client (PCC) to advertise to a Path
Computation Element (PCE) that a particular LSP belongs to a
particular Disjoint Association Group; thus, the PCE knows that the
LSPs in the same group need to be disjoint from each other.
This document is a product of the Path Computation Element Working Group of the
IETF.
This is now a Proposed Standard.
