Management of the broadband networks • Goal: End-to-end management of sub-networks: • Service management rather than network management. • Requirements for sub-networks: • Rapid service provisioning; • Autonomous service restoration; • QoS sensible application acceptance. • Management areas of importance: • Configuration: service provisioning, autonomous systems configuration, • Performance: QoS report.
