Novel methods on survivability for next-generation optical networks

Nowadays our society has increasingly depended on a wide variety of essential services offered by the distributed network infrastructures such as telecom, emergency, marketing, banking, education, science, and government. Once an infrastructure fails on failures or attacks, the social and economic damages may be catastrophic and even fatal. Since most of the infrastructures are supported by optical network at core, survivability against failures and attacks is therefore vital for the optical Internet. In this work, security and recoverability models, i.e., methods of attack tolerance and fault tolerance in the umbrella of the optical Internet is discussed. New features of next generation Internet, existing investigations on the two subjects, as well as new potential methods directions are presented.
