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

The Evolution of Optical NetworkingDWDM 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

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.

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
