University College London is London’s leading multidisciplinary university. UCL is one of the premier universities in the UK and is consistently ranked as one the top universities in the world. UCL has been at the forefront of computer networking research for many years, operating the first international link to ARPANET from 1973, which later became the Internet, providing a gateway between the US and European networks.

UCL is the project coordinator of ENVISION and is also leading the workpackage on Network-Aware Overlay Applications. UCL brings to these activities its expertise in network optimisation and P2P live streaming research, including: incentives mechanisms for P2P application users, distributed data management and application-layer anycast, swarming algorithms for high-definition real-time video from a single static source, network resource management, QoS and traffic engineering mechanisms for IP networks, network modelling, simulations and prototyping.

Alcatel-Lucent develops and integrates technologies, applications and services to offer innovative global communication solutions, enabling telecom operators, Internet Service providers companies and public administrations to deliver the multimedia services their customers and users need in a broadband world.
