Live demo of low-latency and timing-accurate mobile x-haul based on SDN-enabled 100G Ethernet aggregator


Published on

At ECOC 2018 in Rome, we presented a joint demo with our partners that addressed key challenges facing today’s network operators as they look to support emerging 5G use cases such as augmented reality and mission-critical communication. The showcase, which involved pioneering SDN-based Ethernet technology capable of delivering ultra-low and deterministic latency for time-sensitive mobile services, was selected by ECOC judges for as the winner of the Best Demo Award.
