Generalized Multi-Protocol Label Switching (GMPLS) is one of the most promising candidate technologies for a 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 Multiplexers (ADMs)@ photonic cross-connects (PXCs)@ optical crossconnects (OXCs)@ etc. These physically diverse devices differ drastically from one another in dynamic provisioning ability. At the same time@ the need for dynamically 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 Label Switched Path (LSP) provisioning performance in GMPLS networks@ specifically the dynamic LSP setup elease performance. These metrics can be used to characterize the features of GMPLS networks in LSP dynamic provisioning.
