Service restorability in degree-based wavelength division multiplexing networks

Service restorability is a network-wide parameter for a specific failure scenario that is dependent on the physical topology of the network. Previously network topology generator models for generating random models were based on structural models. However, the Internet and most real world networks follow degree-based models. Service restorability in degree-based wavelength division multiplexing (WDM) networks is analyzed for single-link and dual-link failures for two degree-based models. The main finding is that degreebased WDM networks have very high restorability even under dual-link failures.
