ISO/IEC 29341-18-4:2011(E) describes the device definition which is compliant with the UPnP Device Architecture version 1.0. It defines a device type referred to herein as RADiscoveryAgent device. The RADiscoveryAgent device is a UPnP device that provides the functionality capability for synchronizing the UPnP discovery information between two remote networks. The Remote Access Discovery Agent functionality is a combination of a RADASync service and a control point functionality that interacts with a remote RADASync service running on the remote network. Each control point is pushing discovery information about devices available in its local area network to its corresponding RADASync peer. This device provides control points with the following functionality:
- Ability to push discovery information from a remote network that will be used to recreate and propagate the original information into the local network.
- Ability to propagate multicast events from a remote network into the local network.
