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 realize traffic engineering algorithm performance and scalability tests.

3 -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.
