12 Drivers for New Architecture  Lease of circuits due in October 2006  Network consolidation for cost saving  Need for next generation network testbed  Better network performance  Network utilization and operations efficiency  No single point-of-failure, highly fault tolerant  Network scalability  More demands of integrating optical lightpaths with IP services

13 Design Considerations  IP and optical network being integrated into one  One backbone providing services for two virtual networks and dedicated lightpaths  Optical at the core, routing at the edge  Packets transmitted over Lightpaths between GigaPOP and core nodes  Multi-point communication among core nodes with MPLS technology  Reuse the equipment to save the cost  Automated protection using UPSR/Spanning Tree for link failure  Lambda-based network
