摘要： Networking resilience is the ability to provide and maintain an acceptable level of service, albeit potentially degraded from nominal, in the face of faults and challenges to normal, including adversarial attacks. This paper explores the concept of resilient optical networks and scopes the important issues to be addressed in a sensible architecture. The solution includes monitoring and probing to determine the states of potentially unreliable network substrates, assessment of resilient network operating regimes, isolation of compromised assets, deployment of mitigation measures that may require communication over unreliable substrates and suggestions for resilient architecture design and improvement. The architecture construct evolves around a robust control plane that uses cognitive techniques to assess network states and automatically reacts to the on-set of impairments and attacks involving all the network layers from the Physical Layer to the Application Layer.
