Control of Internet Congestion by Pricing
As another example of the close linkage in the CRN between the technical, business and economist communities this project considers Internet pricing mechanisms. Congestion pricing is concerned with the efficient sharing of network bandwidth. With appropriate pricing, high-value applications gain priority, and the network can be used flexibly by new applications.

CRN Strategic relationship with EPSRC
The CRN has a strategic relationship with the Engineering and Physical Sciences Research Council (EPSRC), the UK government’s leading funding agency for academic research and training in engineering and the physical sciences. We work closely with EPSRC to agree topic areas that are appropriate for EPSRC support and we benefit greatly from their expertise in individual project definition, proposal evaluation and the selection of university partners.

Future Concepts in Wireless Networking
Wireless networking systems currently operate in what is essentially a point-to-point fashion. Network implementations using today’s techniques make inefficient use of spectrum and do not scale to produce the high-bandwidth systems needed for ubiquitous access in the future.

Future Resilient Internet Architectures
Distributed Denial of Service (DDoS) attacks are increasing in number and intensity as organised crime is now able to secure the services of potentially millions of computers formed into ‘BotNets’ that are available for rent in order to launch attacks. DDoS attacks consume network resources and, of course, are potentially damaging to a business that relies on web-based commerce. The extent of the problem is sometimes hidden as many businesses are reluctant to talk in detail about attacks that they have suffered or mitigation techniques that they employ.

Internet Mediated Interactions
One of the key principles of the CRN is the ability to go beyond pure technology and to bring together research work relating to economic, social, and regulatory aspects of communications. This work exemplifies the principle involving academics from economics, computer science and government studies departments at UCL and Oxford. This research is aimed at analysing the factors that determine participation in internet-mediated transactions and has two key themes: developing a methodology for evaluating the web structure of e-government and investigating design mechanisms for fund-raising on the internet

Photonics in Communications Networks
Photonics now provides the backbone for communications throughout the world and is also widespread in the world of computing for very fast access to storage devices. Although excellent incremental work continues, the basic techniques currently used in optical fibre transmission were developed in the 1980s and 90s. The objective of this work is to investigate radically innovative techniques that can bring photonics into entirely new areas of communication to enhance the economics of very high bandwidth access and networking.
