This white paper discusses how virtualization of the broadband home gateway is an architecture evolution that will dramatically improve operating efficiency and customer satisfaction for service providers. Virtualization brings the promise of open networking, improved day-to-day network maintenance and simplified deployment of advanced services to millions of residential subscribers, even when the...se subscribers use home-gateway systems from different makers.
Residential broadband services have advanced significantly in the last two decades. We have progressed from a single-user broadband modem, through Voice over IP (VoIP) services and multi-user home routers and on to support for wireless services and today's emerging requirements for community Wi-Fi and smart home applications. Despite all these changes, the access network architecture remains the same: processing and controlling home traffic is entirely implemented on residential systems. Adding such advanced services as secured networking, mobility over community Wi-Fi, and home automation will further accelerate the growing complexity of the "Connected Home Logic" and the challenges associated with legacy network architecture.
