The evolution of IP and ATM share some common drivers. Both of them are addressing efficient network resource utilisation. In order to evaluate the options and combinations offered by these technologies the DIANA project is looking into the areas where ATM ...
We present a multicast routing protocol called Distributed Core Multicast (DCM). It is intended for use within a large single Internet domain network with a very large number of multicast groups with a small number of receivers. Such a case occurs, for exa ...
In this paper we investigate benefits of classifier combination for a multimodal system for personal identity verification. The system uses frontal face images and speech. We show that a sophisticated fusion strategy enables the system to outperform its fa ...
Multimedia services, audiovisual applications composed of a combination of discrete and continuous data streams, will be a major part of the traffic flowing in the next generation of high speed networks. The cornerstones for multimedia are Asynchronous Tra ...

We present Asymmetric Best-Effort (ABE), a novel service to provide a throughput versus delay jitter service for IP packets. With this service, every best effort packet is marked as either Green or Blue. Green packets, typically sent by real-time applicati ...
We focus on packet video delivery, with an emphasis on the quality of service perceived by the end-user. A video signal passes through several subsystems, such as the source coder, the network and the decoder. Each of these can impair the information, eith ...

Video applications are expected to generate a significant proportion of the traffic in the future B-ISDN. We consider the different possibilities for the transport of video signals provided by the service classes defined by the ATM Forum and the ITU-T, foc ...
This paper studies the issues of flexibility and scalability in the context of network security. In particular, it concentrates on authentication and key distribution services suited for a variety of communication paradigms, network environments, and end-d ...
