12 How to match the jobs? Alarm Management Configuration Management Performance Management Link Verification Dynamic Routing Signaling /G.709 /G.709 Presentation Title 12

13 The way to go? Alarm Management matches with Link Verification Configuration aligned with nominal Routes Performance Management Signaling Link Verification Dynamic Routing Signaling /G.709 Presentation Title 13

14 How to manage an ASON? Conclusion > Network Management will keep it s role of managing Network Resources > Control Plane will take over instant routing decisions based on network status > Network and Control Plane need to operate on the identical resources keeping each other aligned. > The art of managing an ASON is to balance management capabilities with performance Presentation Title 14
