Holding-time-aware spectrum allocation algorithm for elastic optical networks
18
TL;DR: A holding-time-aware algorithm is proposed, which considers different overall fragmentation states in the network to select the optimal approach to allocate spectrum, and the results indicate that the proposed algorithm obtains lower blocking probabilities and is able to make more use of network resource compared with traditional algorithms.
