Abstract:
     In particular networks such as those used by financial
     institutions, network performance criteria such as latency are
     becoming critical to data path selection.  However cost is still an
     important consideration.  This leads to a situation where path
     calculation involves multiple metrics and more complex objective
     functions.

     When using GMPLS control plane, there are many scenarios in which a
     node may need to request a remote node to perform path computation
     or expansion, like for example multi-domain LSP setup, Generalized
     Multi-Protocol Label Switching (GMPLS) User-Network Interface (UNI)
     or simply the utilization of a loose ERO in intra domain signaling.
     In such cases, the node requesting the setup of an LSP needs to
     convey the required objective function to the remote node, to
     enable it to perform route computation in the desired fashion.
     Similarly, there are cases where the ingress node needs to indicate
     a TE metric bound for a loose segment that is expanded by a remote
     node.

     This document defines extensions to the RSVP-TE Protocol to allow
     an ingress node to request the required objective function for the
     route computation, as well as a metric bound to influence route
     computation decisions at a remote node(s).
