Abstract: An example method for Extensible Messaging and Presence Protocol (XMPP) based Universal Plug and Play (UPnP) device architecture for cloud computing in a network environment is provided and includes mapping a first content according to UPnP device architecture protocols to at least one stanza according to Extensible Messaging and Presence Protocol (XMPP), generating data comprising the at least one stanza and a second content formatted according to UPnP device control protocols (DCPs), and transmitting the data in an Extensible Markup Language (XML) stream over an XMPP network from a first UPnP entity in a first UPnP network to a second UPnP entity in a second, remote UPnP network. In specific embodiments, the second content includes vendor specific information conveyed in appropriate device descriptions and service descriptions.

Abstract: Intermediate devices (1) such as server devices receive streaming information (2) from source devices (3) and transmit the streaming information (4) possibly in a time-shifted manner via networks (5) to destination devices (6) such as client devices in client-server-combinations. To offer the time-shifted manner, the intermediate devices (1) comprise circular buffers (16) for storing at least parts of the streaming information (2, 4). By providing the intermediate devices (1) with transmitters (17) for transmitting buffer data (7) to the destination devices (6) and with receivers (18) for receiving request data (8) from the destination devices (6), for example in accordance with a network protocol, with the request data (8) defining sizes of time-shifts expressed at the hand of the buffer data (7), the circular buffers (16) can be used more flexibly by one destination device (6) and can be used by more than one destination device (6) in a relatively flexible environment.
