IEEAF OC-12 Link • No directly link to Europe • IEETF donate a OC-12 Link from New York to Amsterdam • Convert from SONET to SDH
TWAREN Optical Network Lab • Integrated DWDM/Next-Gen SDH/IP laboratory • Deployment completed in early Feb. • Research Projects: • Management /support by NSC • SLA collaborate with NCU • QoS collaborate with NTHU • UCLPv2 collaborate with CRC in Canada • Scheduling System • http://optlab1.twaren.net/calogic/.
Lab Network Topology MSTP/MSPP A (2 shelves) GE STM-64 Dark fiber 7609 A 7609 B 7609 C MSTP/MSPP B (1 shelf) MSTP/MSPP C (1 shelf)
TWAREN LightPath Control System • A web-based control and resource management system • Platform : Linux • Tools : PHP+ Shell script+TL1 Toolkit • Test environment : TWAREN optical network lab
Steps to Create a LightPath TL1 Tool-kit TL1-Command Server DataBase • Use TL1-toolkit to query real-time status • Check if path is supported • Check if bandwidth is supported • Execute the SPF algorism to find the best path • Setup the connection between devices • Synchronize the database
