Abstract

Orthogonal frequency division multiplexing technology is used to satisfy the ever increasing traffic demand. This technology is been used in SLICE optical network for the spectrum allocation. For effective resource utilization, bandwidth allocation is done at sub-wavelength and super-wavelength level. Routing and spectrum allocation problem is solved by many researchers using heuristic methods and many algorithms have been proposed for this problem. However the light path established must satisfy the spectrum continuity constraint. Here we consider the RSA problem which is divided into routing problem and spectrum allocation problem. The routing problem is solved by two methods such as shortest path routing (SPR) and balanced load spectrum allocation routing (BLSA).Heuristic algorithms are proposed for spectrum allocation techniques such as best fit, Next Best fit, Worst fit and Gold fit. For these techniques simulation is developed and its performance is analyzed by the parameters such as fragment utilization and blocking frequency. (C) 2018 Published by Elsevier GmbH.
