  1. The Evolution of Optical Networking DWDM in Commercial Networks • Fiber Relief/Increased Capacity Requirements • Numerous Newly Deployed National Backbones • Nexxia • Frontier • Quest etc. • Most deploying underlying SONET transport architecture to meet commercial needs

  2. The Evolution of Optical Networking DWDM in R&D/Educational Networks • Primarily Driven by • Requirement for increasing WAN bandwidth, I.e. OC-48 min. • Efforts to eliminate expensive/unnecessary transport protocols/infrastructure • CA*Net3 • NTON/Abilene/International Net’s? • Regional Nets now deploying DWDM Optical High-Speed Networks • BCNet • NCIT/CRC/NRC • RISQ • MREN

  3. New R&D DWDM Optical Networks CA*net 3 GigaPOP SRnet WURCnet Mrnet OC-12 ACORN Calgary Regina St. John’s BCNet Optical Net Winnipeg RISQ Optical Net NCIT/CRC Optical MAN Teleglobe Vancouver OC-48 OEP Halifax Ottawa Montreal STAR TAP OEP? MREN Optical MAN Seattle Pacific OEP? NTON/Abilene/C3 Toronto Chicago New York

  4. Direction & Results of This Evolution • Developing of Points of Convergence of Wavelength, High Bandwidth Traffic • Evolving towards Next Generation Optical Internet Exchange NAP’s in Several Locations • Ottawa, Vancouver, Chicago. Seattle? • Eventually will be numerous others across US and internationally.

  5. Future Needs/Present Problems • No available Layer 1/2 Optical Switching Devices with provisioning capability (replace ATM L2 PVC’s) • Present capabilities only allow static routing of wavelengths • Protocols for Next Gen. NAP’s • IP/ATM/DWDM • IP/DWDM • Frequency Conversion in Optical Hub • Optical Multiplexing in Router/Switch cards • Migration Path from Present Technologies
