In this OFC presentation, Niall Robinson reviewed the current status of white box technology and explored the future of this exciting space. He also looked at the most recent activity of the Open Optical and Packet Transport Project, the design of the Voyager solution and at where this fast-moving networking industry initiative is headed.

Open Optical Packet Transport Project
This project group will define dense wavelength division multiplexing (DWDM)
open packet transport architecture that triggers a new pace of technology
innovation and flexibility, and avoids implementation lock-ins. Open DWDM
system includes open line system & control, transponder & network
management, packet-switch and router technologies.

Disaggregation and deployment
Two types of disaggregation
• Network
• Network element

Integration of disaggregation
Some lessons learned
Technical/technology aspects are not the most challenging part
Good project managers are worth their weight in gold!
Don’t underestimate the legal workload
Your roadmap is not your own
Documentation is critical
Stay open minded
