For CSPs, the transition to Adaptive Bit Rate (ABR) is well underway.  What was once a rigid hierarchical service topology has been federated into highly distributed Content Delivery Network (CDN) caches.


This CDN network has been disaggregated, virtualized and further distributed into the Edge Cloud.  The PVR function is also moving from local (STB) storage to the cloud.   Using a variety of heuristics, high-demand video content is stored at the network edge.

These cloud functions quickly become highly dynamic ‘black boxes’, amplifying operational blind spots.  SONAR4 edge analytics shines sunlight on these dark corners of the modern service path.
