Vodafone Group and Nokia have collaborated to test the viability of L4S (low-latency, low-loss, and scalable) technology over passive optical networks (PON), which can improve experience of consumers in daily internet activities, such as video conferencing and gaming.
Nokia’s research arm Nokia Bell Labs and Vodafone’s Fixed Access Centre of Excellence recently demonstrated L4S running over PON in telecom operator’s lab in Newbury, United Kingdom (UK).
The demonstration was performed on an end-to-end fixed access network built with Nokia’s technology. It consisted a broadband network gateway (BNG), a PON optical line terminal (OLT), multiple PON optical network terminals (ONTs), and Wi-Fi access points.
Nokia and Vodafone mentioned that the tests showed extremely low and consistent end-to-end latencies when travelling across every element of the network.
While the Vodafone and Nokia Bell Labs tests were conducted using PON networks, L4S can be implemented over any access technology, wireless or wireline, and applied to any latency- dependent application.
