Abstract
A novel class-based first-fit spectrum allocation policy is proposed for dynamic
Flexgrid optical networks. The effectiveness of the proposed policy is compared
against the first-fit policy for single-hop and multi-hop scenarios. Event-based
simulation technique is used for testing the spectrum allocation policies under
both Fixed Routing and Fixed Alternate Routing algorithms with two shortest
paths. Throughput is shown to be consistently improved under the proposed
policy with gains of up to 15 % in certain scenarios.
