4. Motivations (1/2) • What is needed to deploy network solutions for “Broadband for All”? • There are two major bottlenecks: • “last mile” • “core/metro end-to-end networking”

5. Motivations (2/2) • What are Customers’ requirements ? • More bandwidth at lower costs • Flexible selection of service provider • On-demand bandwidth requests (e.g. Bandwidth on Demand) • Configurable connectivity (e.g. for Optical VPN) • Different levels of SLA • What are Providers’ requirements ? • Optimised solutions that reduce CAPEX and OPEX : • Fast and simple provisioning • Simplified interworking with other providers • Scalability to a large number of Customers • Different levels of QoS and survivability strategies

6. Nobel overall goal To carry out analysis, feasibility studies and experimental activities on innovative solutions and technologies for intelligent IP/optical networks
