Kurzfassung englisch:
The paper discusses in general how to use control loops with impairments monitoring and mitigation for the control and management of dynamically routed all-optical networks. To do so the basic problem is outlined, constraint light-path provisioning reviewed, the cyclic performance optimisation problem discussed and control-loop demands derived. The view from the network-layer dominates as it is assumed the link between the connectivity sold to customers and the resources required for providing it. We conclude that dynamic all-optical networks are possible; impairments mitigation within control-loops effectively helps to increase the overall performance and reduces the demand for quality of transmission headroom to cope with transients from dynamic traffic assignments. Scenario independent control-loop specs are found too restrictive to be feasibly met and therefore a scheme with autonomous control-loop operation targeting on stabilization via the physical-layer control-loops and optimisation via an intelligent performance aware light-path routing is proposed.
