An advanced 5G feature that has been successfully tested by Deutsche Telekom (DT) and Ericsson promises to deliver the coveted immersive experience for time-sensitive applications such as cloud gaming. In a recent demo, the cooperation partners showed how the Low Latency Low Loss Scalable Throughput technology (L4S) significantly reduces the delay in an interactive cloud-based video game.
L4S is an advanced feature that will improve the experience quality for latency sensitive or time sensitive use cases like cloud gaming and augmented reality / virtual reality (AR / VR) applications. To illustrate the benefits of L4S, Ericsson and DT recorded an interactive cloud-based boat race with and without this technology. The demo was played over a cellular network and showed the difference in the gaming experience between an L4S-capable 5G connection and a connection without this feature for low latency times.
The results showed clearly visible jitter peaks in the game without L4S, while the game ran smoothly with this 5G function.
Alex Choi, SVP Technology Strategy & Innovation, Deutsche Telekom, says: “Consistently low latency in cellular networks guarantees the best experience for users of time-critical applications. Together with Ericsson, we have demonstrated the unique advantages of managed latency with L4S technology over 5G . Together we will continue to drive the introduction of L4S. This will enable a consistent and scalable delivery of high-quality 5G and edge-enabled services for developers and customers. ”
Per Narvinger, Head of Product Area Networks, Ericsson, says: “Our latest milestone with Deutsche Telekom shows how the L4S feature can significantly improve the performance of time-critical, high-speed applications in 5G networks. Consistently low latency is an important one Factor in many new 5G services and a need to step up performance beyond 4G. This L4S feature will help take existing 5G use cases to a new level and enable new applications that communications service providers are offering to consumers and businesses can.”
L4S is a new technology based on a standardization of the Internet Engineering Task Force (IETF) and offers high throughput and low latency for IP traffic, resulting in improved, fast management of rate adjustment and a reduction in network congestion, queues and packet loss.
L4S relies on ECN (Explicit Congestion Notification) in the IP header to indicate to the application that queues are being created in the radio access network. The congestion signals are then managed on the sender and receiver side thanks to scalable congestion control algorithms. The technology, in turn, signals to the application server that it has to adjust the bit rate of the application in order to achieve the capacity of the established communication link. As a result, L4S offers a seamless user experience even with variable traffic loads and radio conditions.
