The one-time fantasy of routing light is slowly turning into reality. The race is well and truly on to develop and deploy the optical devices that will deliver tomorrow's "intelligent optical core".
While industry bodies like the IETF (Internet Engineering Task Force) and OIF (Optical Interworking Forum) are busy developing standards to ensure a cohesive evolution, vendors wanting to maintain a competitive advantage are already developing products that span the gap between the IP and optical layers. But with the standards still evolving, how can anyone be sure that their devices will interoperate, let alone deliver on performance expectations? At this early stage of development, functional and conformance testing provides vendors with confidence that they are on the right track.
