David J. Greaves, Ph.D.


Dr. David Greaves, MIEE, completed his Ph.D. at the University of Cambridge in 1989 on the subject of ATM metropolitan area networks. For four years he was a research engineer at Olivetti Research in Cambridge, where he developed ATM prototype switches and line interfaces.

He was one of the first advocates of ATM technology outside the core network. In 1993, he was network architect for the Cambridge Interactive Television Trial, which was the world's first test bed to provide ATM network connectivity all the way to the home. This trial ran for 18 months and served more than 50 homes and schools.

Currently he is a University Lecturer in Cambridge and also Chief Scientist at Virata Corporation, a leading supplier of ASICs and software for DSL applications. Dr. Greaves is also involved with AT&T, BT, AMG Ltd and Tenisontech Ltd. Dr. Greaves is currently a member of the Systems Research Group and undertakes research in the area of hardware design and system specification with an emphasis on networking.

He has recently been working on tools for the Verilog language using formal methods and the HOL theorem prover and is now applying these techniques to more general hardware and software system specification and codesign using high-level languages.

In the Hanlan project, Dr. Greaves and his group are investigating the integration of media-access control and VDSL modem design for high-performance networking over home phone wiring within the home. This project integrates ATM and Frame traffic at the physical layer and uses novel synchronization techniques to avoid preambles, which would otherwise dominate and reduce efficiency.

In a similar way to mobile multimedia radio projects, issues of the variability of available bandwidth to higher layers may eventually affect application, protocol and QoS vector design. In the Warren project, Dr. Greaves' group designed and implemented a complete home multimedia network architecture and parts of this work are being standardized.

An extensive position paper describing this work appeared in the January 1998 Edition of IEEE Networking Magazine. In the Autohan project, Dr. Greaves' group is investigating the use of declarative languages based on composite events to control and monitor networks, with a view to providing intuitive and intelligent user interfaces to home networks.

Dr. Greaves serves Rim Semiconductor as a member of our Technical Advisory Board.

austin: A while back they were still consulting with him, but I don't know what the current status of your question is.
