Abstract

The Universal Plug and Play (UPnP) technology is widespread among many multimedia consumer electronic devices and applications, but its usage is typically restricted to home (local) networks. The objective of this work is on one hand to extend the use of UPnP beyond home networks with the help of the Session Initiation Protocol (SIP) technology and on the other hand the remote management of the Media Servers through OSGi technology. The proposed architecture allows the distribution of devices and services, keeping the same application functionality and usability. Thus, it is possible to transparently discover and invoke services in devices from two different home networks, creating end to end connections. The development has been implemented over IPv6; explaining all required changes in firmware and software, while keeping compatibility with IPv4 so that future changes are transparent for the user.
