We 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 technology
