UPnP/spl trade/1.1 - designing for performance and compatibility

The UPnP/spl trade/ 1.0 peer-2-peer home networking architecture is an important step towards interoperability of networked consumer devices, realizing the connected home experience. This work describes how the UPnP/spl trade/ 1.1 device architecture improves the UPnP/spl trade/ 1.0 device architecture in a backwards-compatible way, giving improved discovery and improved compatibility with referenced standards.
