LSP setup delay

Label Switched Path (LSP) Dynamic Provisioning Performance Metrics in Generalized MPLS Networks RFC 5814

An LSP setup delay is an important metric to assess the quality of provisioning of a GMPLS control plane on a network. A longer LSP setup delay may incur in higher overhead for he requesting application and the impact is worsen the shorter the LSP lasting time is.

The delay itself consists of link propagation delay and nodal processing delay, and this metric may be used as testing and diagnostic of the control channel performance. The metrics unit used is either a real number of milliseconds or undefined. The setup delay metric is expressed in milliseconds.
