Evaluation of strategies for dynamic routing algorithms in support of flex-grid based GMPLS elastic optical networks

摘要

We evaluate OSPF-TE extensions within GMPLS framework in support of flex-grid optical networks. Based on OSPF-TE LSAs, two routing strategies are proposed achieving up to 15% and 70% respectively improved blocking ratio for low loaded network (10–30 Erlangs) compared to the shortest path scenario.
