Extending UPnP QoS standard for reducing response delay in multimedia home networks

Abstract

A model has been developed to provide an UPnP communication implementation that reduces QoS negotiation delay. The proposed model extends the UPnP QoS Architecture standard by adding status information about the network topology and the established traffic flows. The introduced extensions are compatible to the existing UPnP standard. The implementation has been tested under different conditions and the obtained results confirm that response time can be reduced with respect to the standard architecture of about 60% to 92%. Furthermore, the implementation demonstrates that redundant queries can be avoided while the management and distribution of the multimedia content will be optimized. © Institute for Computer Science, Social Informatics and Telecommunications Engineering 2009.
