With the availability of more bandwidth to the end consumer through broadband access, the end consumer is now in a position to receive lot of services from the service provider and through internet. Multiple services can be delivered to the consumer in his home through a device termed as Home gateway or Residential gateway. Home Gateway also known as Residential Gateway is defined as a network interface device that provides means for the residential user to access a service delivered to home, such as telephony, cable TV and Internet service, and also the different services offered by the various smart devices within the home. Essentially the home gateway device provides the necessary connectivity features to enable the consumer to exploit the advantages of a networked home. In technical terms, a home gateway device does the bridging/routing, protocol and address translation between external broadband network and the internal home networks. It acts as a secure firewall, and also is the focal point for applications such as Voice/Video Over IP, home automation etc. Home Gateway is a step towards realizing a consumer need of a digitally connected networked home which ultimately results in any content to be delivered to any place to any device and at any time.

Home Gateway provides lot of benefits to the end consumer as well as to the service provider. The consumer benefits provided by the Home Gateway device include:

Ø Internet connection sharing: It allows multiple devices inside the home to simultaneously access the internet.

Ø In-home file/print sharing: It allows multiple devices inside the home to share a network printer or a file.

Ø In-home Wireless LAN connectivity: It allows various wireless devices inside the home to have wireless connectivity to the Home Gateway.

Ø VPN connectivity to work place: It allows the user to work from his/her home.

Ø Secure connectivity to Home from Internet: It allows the user to connect to his home network from anywhere.

Ø Firewall security: It prevents a home network from the outside attacks

Ø Parental protection: It allows the parents to block access to websites for their children.

Ø Broadband telephony (Voice over IP): It allows the user to make voice over IP calls.

Ø IP Video on Demand: It allows the user to avail video on demand service.

Ø In-home audio & video streaming: It allows the user to stream audio/video content across multiple devices inside the home.

Ø Remote health monitoring: It allows monitoring the health of a person in his/her home from a remote location.

Ø Security surveillance: It allows the user to log on to his/her home security network from a remote location.

Ø Home automation & control: It allows the user to control various smart devices from a remote location.

Ø Remote meter reading

For the Service Provider, the home gateway device provides the following benefits:

Ø New revenue streams due to new and differentiating services/applications

Ø Ability to deliver multiple services through a single consumer premises equipment

Ø Ability to reduce the expensive truck roll costs

With the increased penetration of broadband and with the technological advances in home networking, there is a considerable market demand for the home gateway devices. Currently the applications such as Internet connection sharing, file/print sharing and VPN are driving the sales of Home Gateway boxes, but soon these gateway boxes will be available with Voice, Multimedia and other functionalities also. Allied Business Intelligence (ABI) predicts that the home gateway equipment annual revenues would scale to USD 7.1$ billion by the year 2006.

At the technical functionality level the home gateway device performs the activities such as bridging, routing, security processing (Firewall, VPN), address management, quality of service etc. However the home gateway device may take shape of various physical device personalities. The various physical device personalities of a home gateway is described in Figure-3 below. Examples of the home gateway device personalities available in the market is provided in Table-1 .
