In optical wavelength-division multiplexing (WDM) networks, recent technological progress is enabling dynamic optical transport in which leasable circuits (connections) can be set up and released for a specific duration of time, providing large capacity to bandwidth-hungry applications. Set-up times can be flexible or fixed, depending on the type of the application. Since the interruption of a high-speed...
We propose novel dynamic network control algorithms that reduce the blocking probability for dynamic bandwidth service provisioning. The expected network services include on-demand broad bandwidth provisioning services and layer one VPN. The important service attribute of fairness in terms of path length is effectively achieved by introducing a simple weighting function that considers path length...
