UPnP/spl trade/ 1.1 - designing for performance & 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 paper describes how the UPnP 1.1 device architecture improves the UPnP 1.0 device architecture in a backwards-compatible way, improving discovery and compatibility with referenced standard.
