Abstract

Gain competition in an optical amplifier can result in a performance-degrading reduction in the gain of a channel if the overall input power of the amplifier is increased. A gain competition attack may be realized by one or more attackers (pretending to be legitimate users) increasing their source powers in order to degrade the quality of service seen by other users. In this paper, we study the effect of an optical amplifier gain competition attack in a point-to-point WDM link. By looking at the relative OSNR degradation ratio of the attacked channels, we show that Automatic Gain Control mechanisms can alleviate the absolute OSNR degradation to a significant extent, but cannot immunize the system from performance deterioration if the attacking user's power is strong enough. Adding more amplifiers to a link will enhance the service quality as well as the system's robustness against a gain competition attack at the price of higher network cost.
