Abstract:
In particular networks such as those used by financial
institutions, network performance criteria such as latency are
becoming as 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 for 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 the ingress 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).
