    abstract =  {This document defines PCEP extensions for grouping two unidirectional MPLS-TE Label Switched Paths (LSPs), one in each direction in the network, into an Associated Bidirectional LSP. These PCEP extensions can be applied using a Stateful PCE for both PCE-Initiated and PCC- Initiated LSPs, as well as when using a Stateless PCE. The PCEP procedures defined are applicable to the LSPs using RSVP-TE for signaling.},
