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