Home Networking and Control Based on UPnP: An Implementation

Universal Plug and Play (UPnP) is a popular technology for home networking and control. However, to construct UPnP-based home networks is not easy. Especially, most existing appliances have no UPnP interface, how to connect them to the network is an important issue. A solution of this problem is proposed, where, UPnP control point is embedded in residential gateway, while UPnP device is embedded in so-called UPnP Adapter. The UPnP Adapter has an interface translating the UPnP control messages into the private protocol of the appliance. Besides, user can operate appliances via any control terminal connected to the network. The solution has been implemented with Intel SDK for UPnP Devices. The technical details of the implementation are given in this paper.
