Universal Plug and Play (UPnP) is a set of networking protocol= s that permits networked devices, such as personal computers, pri= nters, Internet gateways, Wi-Fi access points and mobile devices = to seamlessly discover each other's presence on the network and establish f= unctional network services for data sharing, communications and e= ntertainment. UPnP uses -
Universal Plug and Play (UPnP) is an implementation of the generic GUPnP= framework for device discovery and using services from control points. GUP= nP is a library for implementing both UPnP clients and services using GObje= ct and LibSoup. It allows for fully asynchronous use without using threads = and so cleanly integrates naturally into daemons, and supports all of the U= PnP features.
The GUPnP framework consists of the following libraries:
Gateway set up : Internally UPnP uses a script /lib/rdk/gwSetup.sh = to set up the gateway in client devices. Here we sets up the routing table,= DNS setting etc.

XcCal-Device module is responssible for getting the following device dis= covery information.
