    abstract =  {This document discusses a GMPLS (Generalized Multi-Protocol Label Switching) RSVP-TE (Resource reSerVation Protocol with Traffic Engineering) protocol mechanism that enables the network to assign an upstream label for a bidirectional LSP. This is useful in scenarios where a given node does not have sufficient information to assign the correct upstream label on its own and needs to rely on the downstream node to pick an appropriate label.},
