Abstract

As the DWDM distributed multi-domain optical networks has been advocated to be the next generation networks, there is a pressing need to propose a set of effective light path provisioning policies. Meanwhile, with the growth of service types, different types of service should be set in different priority levels and pursuit individual QoS requirements. Thus, a new lightpath provisioning policy in support of hierarchical multi-target QoS is proposed, which is self-adaptive to different services, able to support priority, and designed with a dynamic blocking recovery mechanism.
