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
The continuous growth of traffic volumes is making the consumed energy, in telecommunication networks, a critical issue. In this context, the implementation of new content distribution solutions will speed up this traffic increase. In particular, these solutions will significantly impact the traffic profile in metro networks. The current centralized traffic scenario will move toward a scenario in which the traffic exchanges would be distributed among all the nodes of the metro network. In this work, starting from a real traffic scenario, we estimate a possible traffic evolution, and we design the metro networks, according to different architectures, using integer linear programming formulations. The aim was to understand which architecture can better face the considered traffic evolution. The comparison is performed considering the energy consumption, the network setup and management, and the quality of service ensured by the architectures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
