Optical Networks have been dominated by closed and vendor specific network solutions. The need for greater interoperability, efficiency and simplicity in optical networks are the drivers for the open optical network architecture. We will invite speakers from the industry and vendor communities to discuss and share their views on Open Optical Network architecture. Some of the key issues to discuss are: - How Open Line Systems and optical white boxes could play a role in building NREN networks. - Are these technologies mature enough to rely on? - What are the key issues it is going to solve? - What are the operational consequences of such dramatic network architecture changes? - What have standardizations bodies done in the area of Open Optical Network? - Do we have clear demarcation points between different functional blocks and boxes?
