Paper Abstract

A good dynamic routing scheme is very important to improve the provisioning efficiency of wavelength-routed optical networks. The existing dynamic routing algorithms are usually based on first-come-first-serve (FCFS) scheme to process the lightpath requests one by one. However, multiple lightpath requests may arrive simultaneously and burstly in data-intensive applications, and can not be treated efficiently by using the FCFS scheme. We will propose a new online dynamic routing scheme to process the lightpath requests in batch instead of one by one, which is termed batch-come-batch-serve (BCBS) scheme. A mathematic model and several adaptive routing algorithms are proposed and investigated comparatively. The simulation results suggest that the proposed scheme achieves better network blocking performances.
