Analyzing the advance reservation of lightpaths in lambda-grids

The scheme of advance reservations in dynamically provisioned optical networks is novel, and there are no gridbased applications designed to utilize this scheme. We formally define and analyze this scheme and present a constrained mathematical model for advance reservations. We also introduce FONTS - the Flexible Optical Network Traffic Simulator, a tool for simulating advance reservation, ondemand, and periodic data transfer requests. FONTS is based on a stochastic model and incorporates a variety of variables, which have been identified to accurately model advance reservation requests. FONTS validates the mathematical model and also helps to analyze complex scenarios beyond the scope of this paper.
