Activity Based Sector Synchronisation: Efficient Transfer of Disk-State for WAN Live Migration
Found in: Modeling, Analysis, and Simulation of Computer Systems, International Symposium on
By Sherif Akoush,Ripduman Sohan,Bogdan Roman,Andrew Rice,Andy Hopper
Issue Date:July 2011
pp. 22-31
Live migration of virtual machines is now commonplace but the issue of synchronising storage remains an obstacle to wide-area migration between datacentres. We discuss the range of possible designs for synchronising disk images and argue that we have to be...
Predicting the Performance of Virtual Machine Migration
Found in: Modeling, Analysis, and Simulation of Computer Systems, International Symposium on
By Sherif Akoush, Ripduman Sohan, Andrew Rice, Andrew W. Moore, Andy Hopper
Issue Date:August 2010
pp. 37-46
With the ability to move virtual machines between physical hosts, live migration is a core feature of virtualisation. However for migration to be useful, deployable feature on a large (datacentre) scale, we need to predict migration times with accuracy. In...
A User-Level Approach To Network Attached Storage
Found in: Local Computer Networks, Annual IEEE Conference on
By Ripduman Sohan, Steven Hand
Issue Date:November 2005
pp. 108-114
<p>Modern network attached storage architectures suffer from poor performance, resource management and inflexibility. We examine the problems of current architectures and propose an alternative, built around the precept of doing network storage at us...
A Primer on Provenance
Found in: Queue
By Andy Hopper, Lucian Carata, Margo Seltzer, Nikilesh Balakrishnan, Ripduman Sohan, Sherif Akoush, Thomas Bytheway
Issue Date:March 2014
pp. 10-23
Better understanding of data requires tracking its history and context.
MockDroid: trading privacy for application functionality on smartphones
Found in: Proceedings of the 12th Workshop on Mobile Computing Systems and Applications (HotMobile '11)
By Alastair R. Beresford, Andrew Rice, Nicholas Skehin, Ripduman Sohan
Issue Date:March 2011
pp. 49-54
MockDroid is a modified version of the Android operating system which allows a user to 'mock' an application's access to a resource. This resource is subsequently reported as empty or unavailable whenever the application requests access. This approach allo...
