Comcast has embarked on the industry’s first low latency DOCSIS (LLD) field trials, working in partnership with Apple, NVIDIA and Valve.
According to Comcast, this emerging technology, which it is planning to make available to customers by the end of 2023, is a key component of the Xfinity 10G Network that has the potential to transform the performance of interactive applications and create a foundation for new consumer use cases that have yet to be imagined.
It adds that LLD is a CableLabs technology standard that implements the Internet Engineering Task Force’s (IETF) Low Latency Low Loss Scalable Throughput (L4S) open standards. The L4S standards specify how network links, such as in an internet gateway, can implement a new data packet processing function for latency-sensitive traffic and as a result achieve ultra-low latency.
LLD is an open standard technology that manages low latency application flows over broadband networks. This low latency flow shares the same bandwidth and best-efforts prioritisation as regular traffic and doesn’t adversely impact the quality, speed, or latency of unmarked traffic. App developers mark traffic as latency sensitive, so that LLD can then manage the low latency flows to optimise application performance and quality for customers who use those applications.
While Comcast is conducting these initial trials with its trial partners, any app developers interested in participating can email to express their interest at Low-Latency-Partner-Interest@Comcast.com
