    • Extending Globus to support Multicast Transmission 

      Jeacle, Karl; Crowcroft, Jon (2008-06-26)
      The Globus Toolkit is an open source software toolkit that has become the de-facto standard for middleware used to build Grid services. Globus XIO is an eXtensible Input/Output library for Globus. It provides a POSIX-like ...
    • FLICK: Developing and Running Application-Specific Network Services 

      Alim, Abdul; Clegg, Richard G.; Mai, Luo; Rupprecht, Lukas; Seckler, Eric; Costa, Paolo; Pietzuch, Peter et al. (USENIX, 2016-06-22)
      Data centre networks are increasingly programmable, with $\textit{application-specific}$ network services proliferating, from custom load-balancers to middleboxes providing caching and aggregation. Developers must currently ...
    • FutureGRID: A Program for long-term research into GRID systems architecture 

      Crowcroft, Jon; Hand, S M; Harris, T L; Herbert, A J; Parker, Michael A; Pratt, I A (2008-06-26)
      This is a project to carry out research into long-term GRID architecture, in the University of Cambridge Computer Laboratory and the Cambridge eScience Center, with support from the Microsoft Research Laboratory, ...
    • GREEN IPTV: a resource and energy efficient network for IPTV 

      Ramos, Fernando M. V. (2013-01-08)
      The distribution of television is currently dominated by three technologies: over-the-air broadcast, cable, and satellite. The advent of IP networks and the increased availability of broadband access created a new vehicle ...
    • Jitsu: Just-In-Time Summoning of Unikernels 

      Madhavapeddy, Anil; Leonard, Thomas; Skjegstad, Magnus; Gazagnaire, Thomas; Sheets, David; Scott, Dave; Mortier, Richard et al. (USENIX, 2015-03-27)
      Network latency is a problem for all cloud services. It can be mitigated by moving computation out of remote datacenters by rapidly instantiating local services near the user. This requires an embedded cloud platform on ...
    • Kadupul: Livin' on the Edge with Virtual Currencies and Time-Locked Puzzles 

      Skjegstad, Magnus; Madhavapeddy, Anil; Crowcroft, Jon (ACM, 2015-04-08)
      Devices connected to the Internet today have a wide range of local communication channels available, such as wireless Wifi, Bluetooth or NFC, as well as wired backhaul. In densely populated areas it is possible to create ...
    • Personal Data: Thinking Inside the Box 

      Chaudhry, Amir; Crowcroft, Jon; Howard, Heidi; Madhavapeddy, Anil; Mortier, Richard; Haddadi, Hamed; McAuley, Derek (ACM, 2015)
      We are in a ‘personal data gold rush’ driven by advertising being the primary revenue source for most online companies. These companies accumulate extensive personal data about individuals with minimal concern for us, ...
    • Queues Don’t Matter When You Can JUMP Them! 

      Grosvenor, Matthew P.; Schwarzkopf, Malte; Gog, Ionel; Watson, Robert N. M.; Moore, Andrew W.; Hand, Steven; Crowcroft, Jon (USENIX Association, 2015-03-27)
      QJUMP is a simple and immediately deployable approach to controlling network interference in datacenter networks. Network interference occurs when congestion from throughput-intensive applications causes queueing that ...
    • Reliable ligh-speed Grid data delivery using IP multicast 

      Jeacle, Karl; Crowcroft, Jon (2008-06-26)
      In recent years, much work has been done on attempting to scale multicast data transmissions to hundreds or thousands of receivers. In today's Grid environments, however, a typical application might involve bulk data ...
    • Research data supporting "From photons to big-data applications: terminating terabits" 

      Zilberman, Noa; Moore, Andrew W.; Crowcroft, Jon (University of Cambridge, 2015-08-28)
    • Resolving data center power bill disputes: the energy-performance trade-offs of consolidation 

      Chatzipapas, Angelos; Pediaditakis, Dimosthenis; Rotsos, Charalampos; Mancuso, Vincenzo; Crowcroft, Jon; Moore, Andrew W. (2015-06-09)
      In this paper we challenge the common evaluation practices used for Virtual Machine (VM) consolidation, such as simulation and small testbeds, which fail to capture the fundamental trade-off between energy consumption and ...
    • SCANDEX: Service Centric Networking for Challenged Decentralised Networks 

      Sathiaseelan, Arjuna; Wang, Liang; Aucinas, Andrius; Tyson, Gareth; Crowcroft, Jon (Association for Computing Machinery, 2015-05-18)
      Do-It-Yourself (DIY) networks are decentralised networks built by an (often) amateur community. As DIY networks do not rely on the need for backhaul Internet connectivity, these networks are mostly a mix of both offine and ...
    • Social network support for data delivery infrastructures 

      Sastry, Nishanth Ramakrishna (2011-10-11)
      Network infrastructures often need to stage content so that it is accessible to consumers. The standard solution, deploying the content on a centralised server, can be inadequate in several situations. Our thesis is ...
    • Wild Interdisciplinarity: Ethnography and Computer Science 

      Goulden, Murray; Greiffenhagen, Christian; Crowcroft, Jon; McAuley, Derek; Mortier, Richard; Radenkovic, Milena; Sathiaseelan, Arjuna (Taylor & Francis, 2016)
      Drawing on the experiences of a novel collaborative project between sociologists and computer scientists, this paper identifies a set of challenges for fieldwork that are generated by this wild interdisciplinarity. Public ...
