Broadband Forum standard helps move workloads to metro edge services; trials underway in China

The metro-compute networking architecture will include in-depth integration of computing and network on top of the cloud-based broadband network with the purpose of connecting isolated edge sites – such as Broadband Forum’s CloudCO – as one cloud to serve edge computing services.

“The latest release of TR-466 represents a big step for the industry as the standard will help cloud providers and operators overcome the routing and scalability challenges at the edge. Furthermore, it enables virtualization and disaggregation of edge elements and nodes to run applications in proximity to the customer where latency is important. This is particularly important for enterprise networks and will provide a shareable infrastructure for customers that can be seamlessly managed with reduced complexity,” explains Broadband Forum SDN/NFV Work Area Co-Director George Dobrowski.

“Our work enables faster and more efficient provisioning of low-latency and high-bandwidth edge computing services. TR-466 perfectly complements the Forum’s in-progress work on WT-474 subscriber session steering, which can deliver flexible on-demand bandwidth that detects traffic changes and automatically scales to preserve the user experience. This is achieved by utilizing compute-aware routing and dynamic session steering, as demonstrated at Broadband World Forum. These specifications enable operators to unlock new revenue-generating services,” notes Dobrowski.

Edge computing represents a unique opportunity for operators as they already own a large number of edge sites. The approach, however, inherently enables co-existence with existing legacy edge investments. This will enable them to transform into an ICT service provider and adapt their business offering from bandwidth to network connection, computing and storage to deliver service information and content, not just bandwidth. For Over-The-Top (OTT) streaming, gaming, or Virtual Reality services, providers will be able to save asset investment and Operation and Maintenance (O&M) costs through edge sharing.

Metro-Compute Networking benefits have been recognized by some of the largest and innovative operators in the world with lab and additional field trials including significant activity within China, including China Mobile, China Telecom and China Unicom. In addition, IRTF is preparing a new research group, RISE, following a similar direction in Q4 2021 after the release of TR-466. These proponents consider TR-466 as a key step in helping them move towards the required ICT transformation.

“Until now, no industry standards organization has considered the possible impact on multi-service broadband networks under the trend of edge computing or addressing the unique challenges that this has presented,” says Broadband Forum SDN/NFV Work Area Co-Director Bruno Cornaglia. “This latest Broadband Forum work will see us play a critical role in edge computing and utilize the virtualized network infrastructure to enable carriers to increase revenue via edge cloud services.”
