ABSTRACT:
Disclosed is a method for scaling and extending the reach of UPnP device discovery and eventing by leveraging the use of a peer-to-peer network infrastructure. Peer-to-peer networking allows for the organization of a set of nodes into a group for efficient exchange of information and the group has an efficient and scalable mechanism for flooding data to all members in it. In one embodiment one PC in a peer group can receive device discovery announcements and subscribe for device event notifications. A discovery proxy and an eventing proxy running on the PC package the announcement and/or notification in a record and proceed to flood it to the group. The group flooding semantics route the notification to the subscribed controllers, which can subsequently take suitable action. Ultimately, this method produces a result whereby device discovery and eventing tasks can be fulfilled by locating the closest peer and obtaining the device announcements and notifications from that peer.
