  • STRATUS: Towards returning data control to cloud users

    Ko, Ryan K.L.; Russello, Giovanni; Nelson, Richard; Pang, Shaoning; Cheang, Aloysius; Dobbie, Gill; Sarrafzadeh, Abdolhossein; Chaisiri, Sivadon; Asghar, Muhammad Rizwan; Holmes, Geoffrey (Springer International Publishing, 2015)
    When we upload or create data into the cloud or the web, we immediately lose control of our data. Most of the time, we will not know where the data will be stored, or how many copies of our files are there. Worse, we are ...
  • Cardigan: SDN distributed routing fabric going live at an Internet exchange

    Stringer, Jonathan; Pemberton, Dean; Fu, Qiang; Lorier, Christopher; Nelson, Richard; Bailey, Josh; Corrêa, Carlos N.A.; Rothenberg, Christian Esteve (IEEE, 2014)
    Software Defined Networking (SDN) is an active area for network research, with many organizations exploring the opportunities provided by the decoupling of network control from packet forwarding. However, questions remain ...
  • Cardigan: deploying a distributed routing fabric

    Stringer, Jonathan Philip; Fu, Qiang; Lorier, Christopher; Nelson, Richard; Rothenberg, Christian Esteve (ACM, 2013)
    SDN is an active area for network research, with many organisations exploring the opportunities provided by the de-coupling of network control from packet forwarding. Previous work has suggested that a hybrid networking ...
  • Libtrace: A packet capture and analysis library

    Alcock, Shane; Lorier, Perry; Nelson, Richard (ACM, 2012)
    This paper introduces libtrace, an open-source software library for reading and writing network packet traces. Libtrace offers performance and usability enhancements compared to other libraries that are currently used. We ...
  • Measuring the impact of the copyright amendment act on New Zealand residential DSL users

    Alcock, Shane; Nelson, Richard (Elsevier, 2012)
    The Copyright (Infringing File Sharing) Amendment Act 2011 (CAA) is a New Zealand law that aims to provide copyright holders with legal recourse when content is illegally shared over the Internet. This paper presents a ...
  • Passive detection of TCP congestion events

    Alcock, Shane; Nelson, Richard (2011)
    Detailed passive analysis of TCP sender behaviour requires accurate identification of congestion events. Previous tools that attempt to provide such information do not incorporate the behaviour of recent operating systems ...
  • Measuring and characterising inbound sessions in residential DSL traffic

    Alcock, Shane; Nelson, Richard (Institute of Electrical and Electronics Engineers., 2011)
    It has been assumed that the need for successful NAT traversal discourages residential DSL users from running services or applications that require them to accept connections from remote hosts. However, there are now ...
  • Comparing anomaly detection methods in computer networks

    Löf, Andreas; Nelson, Richard (IEEE Computer Society, 2010)
    This work in progress outlines a comparison of anomaly detection methods that we are undertaking. We are comparing different types of anomaly detection methods with the purpose of achieving results covering a broad spectrum ...
  • Application-Level QoS: Improving video conferencing quality through sending the best packet next

    McDonald, Ian; Nelson, Richard (IEEE, 2008)
    In a traditional network stack, data from an application is transmitted in the order that it is received. An algorithm is proposed where information about the priority of packets and expiry times is used by the transport ...
  • Scalable architecture for prefix preserving anonymization of IP addresses

    Blake, Anthony Martin; Nelson, Richard (Springer, 2008)
    This paper describes a highly scalable architecture based on field-programmable gate-array (FPGA) technology for prefix-preserving anonymization of IP addresses at increasingly high network line rates. The Crypto-PAn ...

  • A Scalable and Fault Tolerant OpenFlow Controller

    Sharma, Karthik Neelakanta (University of Waikato, 2015)
    OpenFlow provides a protocol for updating flow tables in switches. Most current OpenFlow deployments rely on a single controller to control all switches. However, as the number and size of production networks deploying ...
  • Techniques for Failure Recovery in a Software-Defined Network

    Lorier, Christopher (University of Waikato, 2014)
    As our lives become ever more dependent on network connectivity, it becomes increasingly more important for networks to be able to overcome the failure of individual components and continue to function. This thesis examines ...
  • Rating the Significance of Detected Network Events

    Mungro, Meenakshee (University of Waikato, 2014)
    Existing anomaly detection systems do not reliably produce accurate severity ratings for detected network events, which results in network operators wasting a large amount of time and effort in investigating false alarms. ...
  • Modelling and Evaluation of 60 GHz IEEE 802.11 Wireless Local Area Networks in ns-3

    May, Michael (University of Waikato, 2014)
    In this thesis we present modifications made to the popular network simulation environment ns-3 to provide accurate simulation of IEEE 802.11ad Wireless Local Area Networks (WLANs) in the 60 GHz band. There is a need for ...
  • Security Analysis of the Evolved Packet Core for LTE Networks

    Wadsworth, Simon Oliver (University of Waikato, 2013)
    Originally cellular networks handled calls and short messages only. Today, this has been extended to handle packet data services. However now the world is moving towards an entirely IP based mobile service based on LTE and ...
