摘　　要：We investigate the problem of efficiently provisioning connections of arbitrary bandwidth granularities in integrated optical Internet model, and propose a novel dynamic weighted fair routing algorithm (DWFA) that employs QoS-aware flexible adaptive unified routing strategies according to the priority and granularity of the traffic connection request. Performance simulation results of DWFA show that our adaptive approach performs better in terms of traffic blocking ratio, traffic blocking fairness and traffic average logical hop counts than traditional overlay sequential routing scheme such as optical-layer-first routing (OFR) and electrical-layer-first routing (EFR). DWFA is very suitable for solving QoS-based multi-layer integrated routing (MLIR) problem in the next generation multi-granularity integrated optical Internet.
