Virtual CPE

The Criterion Virtual CPE (vCPE) solution provides a framework for service providers to deploy cloud-based customer premise equipment for residential and enterprise customers. Our vCPE solution allows for simpler but much more capable provisioning, administration, customization, and rapid deployment of new services. The Criterion Cloud CPE solution is based on the CORD architecture championed by the ONOS community, which offers an open-source, virtualized, cloud-based service delivery model for network operators.

Benefits

  • Seamless upgrades, monitoring, troubleshooting, and support
  • Customizable platform eases deployment of new services
  • Lowers overall maintenance cost through CAPEX and OPEX savings
  • Integration of third-party services
