As appliance-based network functions get virtualized into VNFs, they are also being relocated to the Edge Cloud.  CSPs are redefining Enterprise services through commercial deployment of Virtual CPE (vCPE) cloud services coupled with low-cost Universal CPE (uCPE) hardware at the customer site.


The uCPE hardware has some compute resources, allowing the managed cloud to extend all the way into the customer site.  This variability in deployment represents a departure from well-established and understood practices of the past, and forms a new challenge in assuring tight SLAs.

SONAR4 enables you to ‘follow the breadcrumbs’ through this multi-layered, multi-site technical environment.
