I am Richard Clegg a Senior Research Associate in the Department of Computing at Imperial College, London (as well as an Honorary Senior Research Associate at University College London). I gained a PhD in Mathematics and Statistics from the Univeristy of York in 2005. My current research interests centre around networks: mainly computer networks but anything where things are associated with other things can be viewed as a network. My Erdős number is three.

This site has been on the web in some form or another continuously since late 1994. You can find the previous version of the site here and the previous previous version here.

Along with Keith Briggs I run the Mathematics of Networks meetings. These (approximately) yearly meetings have been running since 2003.

When not in work I enjoy diving (I am a diving instructor with the British Sub Aqua Club) and brewing.

My research interests include:

- Dynamic network topologies
- Statistical nature of traffic
- Cloud computing
- Software defined networks

In general I'm interested in:

- Data analysis, machine learning
- Statistically rigorous analysis
- Graph theory
- Queu(e)ing theory

I have acted as a reviewer for a number of journals including:

- Journal for Selected Areas in Communications Systems
- Physica A
- Performance Evaluation
- Transactions on Cloud Computing
- Computer Communications
- IEEE Network
- Electronics Letters
- Transactions on Parallel and Distributed Systems
- Computer Networks
- Networks and Spatial Economics
- The Journal of Complex Networks
- New Generation Computing

I am on various Technical Program Committees including:

- Complex Networks --the International Workshop on Complex Networks
- SIMPLEX -- Simplifying Complex networks.
- UKPEW -- the UK Performance Engineering workshop.
- AICT -- the IEEE Application of Information and Communication Technologies
- PMECT -- Performance Modeling and Evaluation of Computer and Telecommunication Networks
- SNS -- the Workshop on Social Network Systems
- EWSDN -- the European Workshop on Software Defined Networking
- NetSciCom -- the IEEE International Workshop on Network Science for Communication Networks
- COMPLEXIS -- the International Conference on Complex Information Systems

This talk describes FLICK a system for the application-specific middlebox. It consists of three parts:

1) A domain specific language for the middlebox that allows easy development of typical middlebox functions.

2) An abstraction, the task graph, that allows the breaking of middlebox functions into easily parallelisable work units.

3) The system -- this implements the compiled language, handles TCP connections and memory management.

The whole system is comparable in speed to a specialist implementation.
