This paper presents an architecture of UPnP Bridge for interconnecting Non-lP devices with heterogeneous network interfaces to UPnP devices on UPnP networks. The proposed UPnP Bridge provides a Virtual UPnP device that performs generic UPnP Device's functionalities on behalf of Non-lP device. This paper defines 3 types of descriptions, Device Description, Message Field Description, and Extended UPnP Service Description in order to reduce the amount of effort required to connect a non-lP device with a new interface or message format to UPnP network. By these three types of descriptions and Message conversion module, developers for Non-lP devices can easily connect the devices to UPnP network without additional programming. So UPnP control point controls Non-lP devices as generic UPnP device. Some experiments validate the proposed architecture, which are performed on a test bed consisting of UPnP network the proposed bridge, and non-lP devices with CAN and RS232 interfaces.
