UPnP: Breaking out of the LAN

Abstract

The use of devices embedded in the environment is limited by users' ability to find them and configure their mobile devices to use them. Existing commercial implementations of device discovery technologies tend to be restricted to local networks and do not scale well beyond those environments. In this paper we introduce an architecture that extends Universal Plug and Play (UPnP) to address these limitations and therefore enable zero-configuration discovery and use of embedded devices across multiple networks.
