Optical Slot Switching Latency in Mobile Backhaul Networks

International audienceWe show that an optical slot switching network fulfills the strict latency constraints of a next generation LTE advanced switching mobile backhaul network. The impact of class-of-service handling when aggregating client data into slots is also quantified. Introduction With the evolution of the optical transport technologies, energy-efficient solutions for the transport in the radio access part of cellular backhaul networks have become available. In this paper, we consider the use of fine granularity optical transport solutions – optical slot switching (OSS), an energy-efficient switching technolog

Multi-MetaRing fairness control in a WDM folded-bus architecture

The paper deals with fairness issues in a slotted, single-hop, WDM (Wavelength Division Multiplexing) optical architecture, based on a folded bus topology, previously proposed as a broadband access system or as a metro network. The peculiar fairness problem arising in this folded bus based architecture is addressed and an extension of the MetaRing protocol to the WDM scenario, named Multi-MetaRing, is proposed. Feasible Multi-MetaRing strategies are defined and analyzed. Both fair access and high aggregate network throughput can be achieved with a low complexity distributed access protocol by properly handling node access through all WDM channel
