4. SYSTEM OVERVIEW
As shown in figure 1, the Residential Gateway is an internetworking device that provides a common termination interface, mediation facility, and enabling mechanism between the service access distribution networks and those of the consumer's in-home networks and devices. The intelligent termination interface of the RG uncouples the technologies and physical media of the access networks from those used in the premises and vice versa, so that evolution and innovation are feasible in both the service delivery and consumer arenas. Further, through an open-ended architecture that is processor controlled and uses plug-in devices for services and features, the RG provides a platform upon which service providers and application vendors can offer a variety of new and creative services while masking the complexity of the service from the consumer. In addition, the RG provides an opportunity for remote management and maintenance.
Residential Gateways create a home network that can manage its own bandwidth and establish internal or external connections on demand. They make the system scaleable to large numbers of signal sources. They isolate home networks from the details of access systems' physical layer through network layer details.
The Residential Gateway should support the following classes of applications:
Communications services -- which includes but is not limited to voice telephony (wired and wireless), video telephony and conferencing, distance learning, and remote access to corporate networks.
Entertainment services -- which includes but is not limited to broadcast, sattelite and cable television.
Information services -- which includes but is not limited to access to online or internet services.
Utility management -- which includes but is not limited to demand side energy management and remote meter reading.
Home automation services -- which includes but is not limited to premises security, lighting,
and applicance control.
