摘要: This paper investigates a generalized protection framework for availability-guaranteed connection provisioning in an optical wavelength-division multiplexing (WDM) mesh network. We develop link-state-modeling mechanism to form dynamic link-state parameter, called link and resource availability (LRA). Such information can be used by standard routing protocol efficiently provision reliable connections. Based on the LRA we then propose connection-provisioning algorithm which guarantee customers' requirements. A new model is developed through our LRA-based provisioning. Numerical results demonstrate performance of proposed approach promising.
