Survivability for All-Optical Network Against Optical Attacks

The use of optical technology, in particular Wavelength Division Multiplexing (WDM), has revolutionized the transmission of voice and data. An enormous and easily accessible bandwidth is available today with the utilization of the considerable optical capacity of the fiber. On the other hand, the optical domain introduces its own set of challenges. Apart from the failure and attack scenarios present in conventional networks, there are certain hardware vulnerabilities present in the optical networks. Optical devices, such as switches and amplifiers are prone to crosstalk and gain competition. To this end, a technique is desired to avoid and minimize data loss due to these optical-domain specific phenomena.
