New Approach to Optical Networks Security: Attack-Aware Routing and Wavelength Assignment

Security issues and attack management in transparent WDM (Wavelength Division Multiplexing) optical networks has become of prime importance to network operators due to the high data rates involved and the vulnerabilities associated with transparency. Deliberate physical layer attacks, such as highpowered jamming, can seriously degrade network performance and must be dealt with efficiently. While most approaches are focused on the developing fast detection and reaction mechanisms triggered in case of an attack, authors propose a novel approach to help deal with these issues in the network planning and provisioning process as a prevention mechanism.
