First experimental demonstration of real-time orchestration in a Multi-head metro network

Abstract

International audienceWe present for the first time the experimental demonstration of a Real-Time control-plane on the Multi-hEad sub-wavElength swiTching (MEET), Metro architecture. The key control assets are calculated and provided to the edge nodes in a form of grant files. These grant files eliminate the contention possibility at source nodes and destinations, thus they offer a lossless passive optical grooming and multiplexing/demultiplexing at the intermediate nodes. The experimental results validate the control plane structure designed based on a deterministic operating system well scalable for a regional metro network

“…Access to the sub-wavelength granularity directly at the optical layer is an alternative to electrical solution to reduce cost and power consumption by saving on electrical transit and electrical-to-optical and optical-to-electrical conversions. Amongst the various Sub-Lambda Photonically Switched Network (SLPSN) solutions, Time-domain Wavelength Interleaved Networking (TWIN) is an interesting solution since it provides optically transparent subwavelength grooming at intermediate/core nodes, while the intelligence and processing power remains at control plane and the edge nodes 1 .…”

“…This method needs relatively complex electronics sampling tools at the receiver side 4 . In previous work, we presented the implementation of the fundamental building blocks including synchronisation and scheduling in a real-time controlled plane at source side on TWIN based test-bed 1 .…”
