Virtual Router VNF enabled the operator to build sophisticated, multi-tier networks within the

virtualized environments and support adding, configuring and moving network services on-demand.

Virtual Router VNF handled the routing to CDNs and other local services supporting OSPF over IPv4 and

scaled out to utilize equal-cost multi-path routing (ECMP) on the edge router towards the x86 cluster, to

achieve redundancy and scalability.

Replacing complex and expensive Layer 3 CPEs with simple low-cost Layer 2 CPE devices

Run on off-the-shelf Intel Xeon E5-2600 servers on Linux

Dynamic provisioning/de-provisioning of residential services

Layer 2 visibility to client devices allowing OTT services to be delivered to a specific end user

High availability through instance remediation

Significantly lower CapEx and OpEx
