UPnP Network Bridge Architecture for Combining Different Networks

Abstract

In home-network system, UPnP Network is widely used because of simple usage. However, UPnP network is only based on TCP/IP and working in the same subnets. Many applications need extended communication. In this research, we implemented a UPnP bridge which binds two different networks into a virtually single UPnP network. This allows a control point to use devices even if registered in the other network segment. Furthermore, the bridge protocol has non-IP abstraction communication, which is able to widen UPnP network to non-IP network.
