  1. “Next Generation Optical Network” José Manoel Duarte Mendes Tania Regina Tronco Fundação CPqD

  2. “Next Generation Optical Network” • Main objectives • To define requirements, scenarios and architecture for core and metro optical networks; • To study advanced traffic engineering and resilience techniques; • To specify and to implement a traffic engineering algorithm; • To realizetraffic engineering algorithm performance and scalability tests.

  3. Network requirements • Architectures reducing OPEX/CAPEX and providing revenues opportunities through new network services; • Fast automatic provisioning; • Automatic Network Discovery; • Separation of service management/control from the underlying multi-service network; • Efficient and standard management and control solutions for end-to-end network services; • Multi-vendor interoperability; • Multi-layer Traffic Engineering; • Multi-layer Survivability. source: http://www.ist-nobel.org

  4. Network Scenario • Network architectures • ASON/GMPLS
