Generalized Multi-Protocol Label Switching (GMPLS) is one of the most
promising candidate technologies for future data transmission
network.  GMPLS has been developed to control and operate different
kinds of network elements, such as conventional routers, switches,
Dense Wavelength Division Multiplexing (DWDM) systems, Add- Drop
Multiplexors (ADMs), photonic cross-connects (PXCs), optical cross-
connects (OXCs), etc.  Dynamic provisioning ability of these
physically diverse devices differs from each other drastically.  At
the same time, the need for Dynamicly provisioned connections is
increasing because optical networks are being deployed in metro
areas.  As different applications have varied requirements in the
provisioning performance of optical networks, it is imperative to
define standardized metrics and procedures such that the performance
of networks and application needs can be mapped to each other.

This document provides a series of performance metrics to evaluate
the dynamic LSP provisioning performance in GMPLS networks,
specifically the Dynamic LSP setup/release performance.  These
metrics can depict the features of GMPLS networks in LSP dynamic
provisioning.  They can also be used in operational networks for
carriers to monitor the control plane performance in realtime.
