A hybrid protocol architecture for peer-to-peer control based on SIP and UPnP

摘要

SIP or Session Initiation Protocol, and Universal Plug 'n Play (UPnP) are application-layer control protocols. SIP is used for creating, modifying, and terminating sessions with one or more participants, through the Internet. UPnP is also a protocol developed by a vendor consortium to enable device networking and control. However, SIP lacks the necessary functionality to work with heterogeneous devices and UPnP cannot be used in a peer-to-peer paradigm. This paper introduces a hybrid protocol architecture based on SIP and UPnP, called Peer-to-Peer Control Protocol (PCP), which can be used for peer-to-peer networking of heterogeneous devices.
