【 摘 要 】

The ability of core networks to manage data transmission of increasing volumeand variation is critical for the success of data-intensive andnetwork-centric applications as they grow in both scale andcomplexity. Traditionally, static optical networks were the dominant transportfor medium and long distance communication. However, these networks can nolonger meet the needs of tomorrow's applications for higherbandwidth at lower cost.New dynamic optical networks greatly improve thereconfigurability of optical terminal systems and support unprecedentedflexibility for high-traffic resource sharing. However, managing dynamic networks poses challenging problems related to scaleand traffic volume.Traditional analytical techniques, which rely heavily onsimplification of network topologies and route choices, are insufficient tounderstand the significant performance differences implied by the subtle pathpreferences of dynamic routing algorithms. This dissertation presents an integrated approach to efficient and robustresource management algorithms for on-demand data traffic on dynamic photonicswitching networks.First, a resource management framework is proposed toconsider both resource dimensioning and routing for optical opaque networks.Idevelop dimensioning and routing algorithms that are efficient to implement androbust to evolutions of traffic load, network topology, and scale.Second,using Poisson traffic assumptions, the thesis develops an opportunity costmodel for analyzing threshold-based dynamic routing algorithms.The model isscalable and provides better congestion management than previous work.Third,applying the dimensioning technique developed in this thesis, I have severalimportant findings on managing dynamically routed optical translucent networks,optical restorable networks, and multiple optical network domains.Finally,the thesis solves a combinatorial optimization provisioning problem for adynamic wavelength service traffic model on an optical translucent network.This work is the first to evaluate the robustness of optical routerearrangement. New solutions are proposed to design an optimal dynamic servicenetwork with rerouting capability.
