• The Large-Scale Geography of Internet Round Trip Times

    Conference paper
    Presented at IFIP/Networking

    This paper describes the collection and analysis of a very large collection of delay data. The data is collected using the Turbo King method (recursive queries of Domain Name Servers). A model is given to fit the data. The data is analysed by continent.

    It is shown that there is a strong relationship between delay and Haversine distance (the distance across the surface of the earth). However, this relationship breaks down in specific cases and occasionally, for some continent pairs, the opposite relationship is shown (longer distance is shorter delay).

  • On likelihood models for evolving graphs

    Invited talk

    This presentation is very like the presentation at Southampton a few months previously. It describes the current incarnation of the Framework for Evolving Topology Analysis.

  • On the relationship between fundamental measurements in TCP flows

    Conference paper
    Proceedings of the International Conference on Communications, pp. 2502-2506

    This paper tries to establish the relationship between TCP throughput and fundamental qualities like round trip time, flow size and loss. The approach is data driven considering large numbers of publicly available data sources.

  • Distributed Overlay Anycast Table using Space filling curves

    Workshop paper
    Proceedings from IEEE INFOCOM Workshop, Global Internet Symposium

    This paper considers the idea of using fractal space filling curves to locate nearby items in an overlay topology.
