All-optical networks (AONs) are nowadays achievable thanks to the development of optical switching and optical amplification. In such networks, data is transmitted from source to destination in optical form. Switching operations are performed in the optical domain without undergoing any optical-to-electrical conversion. AONs are attractive because they promise very high rates, flexible switching and broad application support. However optical performance monitoring and optical network management are essential in building a reliable, high-capacity, and service-differentiation enabled all-optical network. So monitoring and identification of the impairments becoming challenging in the event of transmission failures. In this paper we present a new method to eliminate attack in network. This method offers the benefit of relaxing the high cost and complexity of network.
