A large number of intelligent components for managing the Future Internet have been proposed recently or are currently being investigated. However, before these network components can be deployed in real-life networks, they need to be thoroughly validated through realistic and large scale experiments. Testbed facilities provide a means to set up large scale network topologies but offer only a limited...
DSL aggregation networks are evolving to the standard platform for the delivery of multimedia services such as television and network based personal video recording. These multimedia services introduce large challenges for network operators as they are sensitive to packet loss. Therefore, admission control mechanisms are required to avoid congestion caused by allowing too many sessions. However, as...
The introduction of new added value services such as IPTV has introduced great challenges for today's broadband DSL access networks as these services have stringent quality demands. In an attempt to protect the quality delivery of existing sessions, operators employ admission control mechanisms that limit the amount of sessions transmitted in the network. Current admission control mechanisms require...
The management of access networks to guarantee the Quality of Experience for multiplay services, is complicated by the heterogeneity in service specifics and home network configurations. The appropriate action to restore the QoE is highly dependent on the type of service, the affected user, etc. This requires an almost per-user and per-service management. Through autonomous reasoning, the required...
The access network has become an infrastructure for delivery of multimedia services, such as broadcast TV, voice over IP or video conferencing, to residential users . Compared to more traditional IP services such as e-mail, users demand a higher quality of experience (QoE) for these new services. To guarantee the quality of service (QoS), access network providers have deployed several service enablers,...
A recent important evolution in broadband access network design is the deployment of IP aware access network elements, which allow to introduce access network services beyond basic triple-play. The focus of this paper is on the management of time-shifted television (tsTV), an IPTV service which allows for watching the broadcast content at real-time or with a (small) time shift. An architecture for...
The increasing popularity of multimedia streaming applications introduces new challenges in content distribution networks. Streaming services such as video on demand (VoD) or digital television over the Internet (IPTV) are very bandwidth-intensive and cannot tolerate the high delays and poor loss properties of today's Internet. To solve these problems, caching (a sliding segment of popular streams...
