1 Introduction In today's wired and wireless networks, the trends in networking technology very much point to a dominance of Internet technology with all its flavours. IP is the common " lingua franca " to enable the exchange of data across various networks. There is, however, an increasing divergence in the network control layer: different control(More)
‰ If content could be stored/cached closer to the end users, then content delivery would have been much more efficient ‰ If routers could identify/analyse what content is flowing through them, the search engines would gain much better knowledge of content location and provide information even on " live " streams, ‰ If the network could identify what is the(More)
In this article, the authors discuss some of the challenges and opportunities resulting from the convergence of broadcast and mobile communication services. Starting with an overview of DAB, DVB and the emerging thirdgeneration mobile communication networks – with a special focus on UMTS – the advantages that result from a combination of UMTS with data(More)
The Ambient Networks project addresses the creation of innovative network solutions for mobile and wireless systems beyond 3G. They will enable scalable and affordable wireless networking while providing rich and easy to use communication services for all. The work is geared towards increasing competition and cooperation in an environment populated by a(More)
In this paper, we describe the approaches taken in the 4WARD project to address the challenges of the network of the future. Our main hypothesis is that the Future Internet must allow for the fast creation of diverse network designs and paradigms, and must also support their co-existence at run-time. We observe that a pure evolutionary path from the current(More)
In this paper, we describe several approaches to address the challenges of the network of the future. Our main hypothesis is that the Future Internet must be designed for the environment of applications and transport media of the 21st century, vastly different from the initial Internet’s life space. One major requirement is the inherent support for mobile(More)
This article presents new concepts for network-supported media delivery in mobile networks. Automatic composition and merging of networks are central parts of these concepts. Media delivery is no longer an end-to-end service that only uses the network as an IP transport. Instead, these concepts create a service-aware network and provide customized delivery(More)
