Broadband Forum Launches Project to Enhance Home Networks with L4S Technology

The Broadband Forum has launched a new project to enhance home broadband networks by integrating Low Latency, Low Loss, and Scalable Throughput (L4S) technology. The firm says L4S will enable operators and service providers to meet the growing demand for low-latency performance in interactive applications such as cloud gaming, video conferencing, and extended reality (XR).

L4S Technology

The global standards body will demonstrate to operators and service providers how to implement L4S technology, which was specified by the Internet Engineering Task Force (IETF) last year.

L4S provides network congestion control that was not previously available for latency-sensitive applications, enabling providers to deliver both high throughput and low latency simultaneously. This allows for better user experiences in such applications. L4S offers immediate congestion feedback, ensuring smooth performance even during network bottlenecks.

“We’re keenly aware that low and stable latency, along with high throughput, is fundamental to broadband performance for many interactive applications used in the home. This is especially true for ensuring immersive experiences in applications like cloud gaming,” said Jonathan Newton of Vodafone and Access and Transport Architecture Work Area Director at Broadband Forum.

Phased Implementation of L4S

L4S does not require full implementation across the entire network, and the Broadband Forum’s project will guide phased implementation of L4S technology, focusing on key network bottlenecks before achieving full end-to-end support.
