Multi-Router Home network
The number of routers in the home is increasing
Overtly – Buying a router instead of a WiFi range extender
Covertly – Chromcast, Roku, iControl, NEST, etc.
Encapsulation – The transport and steering of data packets between the home and the the ISP virtualization platform.
Control Protocols – The method used to both provision and manage the home gateway and its services.
