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

Abstract

   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 cross-
   connects (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/release
   performance.  These metrics can be used to characterize the features
   of GMPLS networks in LSP dynamic provisioning.
