3 Main Objectives To deliver an innovative framework for the automated management and rapid deployment of self-organized next-generation networks and services For automated network monitoring and maintenance management tasks Extending the state-of-the-art network management within the Software- Defined Networking and Network Function Virtualization (SDN/NFV) arena Removing the reliance on costly, vendor-specific hardware with an advanced software-based approach Automatically detecting and mitigating a range of common network problems that are currently still being manually addressed by network operators (use case driven) Reducing operational costs and improving user experience

4 Main Technical Goals 1. Automated network monitoring Automatic deployment of NFV apps. Distributed monitoring of network infrastructure. High-level Health of Network (HoN) metrics Multidimensional view of potential network failures, bottlenecks, security threats, intrusions, etc. 2. Autonomic network maintenance High-level tactical corrective and preventive measures to enable autonomic reactive and proactive network maintenance. 3. Automated deployment of network management tools: Automatic reactive and proactive actions Against existing/potential network problems Automatic deployment of distributed services in the network Intrusion protection tools, Load-balancing tools, High-availability routing tools, Transparent cache tools Other network management tools 4. Automated network service provisioning Manage and optimize the usage and deployment of NFV and SDN applications
