Overlay networking protocols and device metadata for controlling and managing home networks and appliances

Many standardization activities have been done for controlling and managing home networks and appliances during past ten years. Such activities include UPnP/DLNA, ECHONET and Continua Health Alliance and so on. However, there is no compatibility among those standards. To solve those problems, we have developed overlay networking protocols and device metadata technologies as a solution for controlling and managing heterogeneous home networks and appliances in a consolidated manner. Peer-to-peer Universal Computing Consortium (PUCC) was established in 2005, to deploy our overlay networking protocols and device metadata technologies toward de facto standardization. To verify the feasibility and usefulness of PUCC technologies, we have developed the PUCC middleware platforms, and PUCC applications using them. We explain PUCC overlay networking protocols and device metadata technologies. We also explain the PUCC middleware platforms and some PUCC applications using them.
