Future Communications Architecture
The Future Communications Architecture project addresses the challenges the network faces because of the evolution of the communications industry (new business models, new applications and new technologies).
We are especially looking at architectural solutions to fundametnal resource allocation problems on the Internet:
- support for Quality of Service differentiation, within the bounds of network neutrality
- protection against Denial-of-Service attacks
Our main proposal, re-feedback, is a change to the Internet Protocol that reveals congestion levels on the downstream paths of any node in network. This information is then used to enhance both the Quality of Service network providers can offer to their customers, and protection against denial of service attacks.
Current activities
Re-feedback is an attempt to develop a new mechanism for the characterisation of path metrics that gives to any node in the network information about the downstream path.
DoS-resistant Internet Architecture, a project with the aim of setting the future agenda for Internet architecture resistant to denial of service (DoS) attacks.
Fairness - we believe that the concept of flow-fairness is fundamentally flawed. We are now starting to explore the economics of fairness in the Internet.
Our research is conducted in collaboration with several universities and collaboratives initiatives:
- the Communication Futures Programme (CFP)
- the Communications Research Network (CRN)
- the International Computer Science Institute's Center for Internet Research (ICIR)
