Papers
Towards predictable datacenter networks
Hitesh Ballani,Paolo Costa,Thomas Karagiannis,Ant Rowstron +3 more
- 15 Aug 2011
TL;DR: The case for extending the tenant-provider interface to explicitly account for the network is made, and the design of virtual network abstractions that capture the trade-off between the performance guarantees offered to tenants, their costs and the provider revenue are proposed.
Symbiotic routing in future data centers
Hussam Abu-Libdeh,Paolo Costa,Antony Rowstron,Greg O'Shea,Austin Donnelly +4 more
- 30 Aug 2010
TL;DR: This paper designs an extended routing service allowing easy implementation of application-specific routing protocols on CamCube, and demonstrates the benefits and network-level impact of running multiple routing protocols.
Sirius: A Flat Datacenter Network with Nanosecond Optical Switching
Hitesh Ballani,Paolo Costa,Raphael Behrendt,Daniel Cletheroe,Istvan Haller,Krzysztof Jozwik,Fotini Karinou,Sophie Lange,Kai Shi,Benn C. Thomsen,Hugh E. Williams +10 more

TL;DR: Sirius, an optically-switched network for datacenters providing the abstraction of a single, high-radix switch that can connect thousands of nodes---racks or servers---in a datacenter while achieving nanosecond-granularity reconfiguration, is proposed.

Camdoop: exploiting in-network aggregation for big data applications
Paolo Costa,Austin Donnelly,Antony Rowstron,Greg O'Shea +3 more
- 25 Apr 2012
TL;DR: Camdoop, a MapReduce-like system running on CamCube, a cluster design that uses a direct-connect network topology with servers directly linked to other servers, is built and demonstrated that it significantly reduces the network traffic and provides high performance increase over a version of Camdoop running over a switch and against two production systems, Hadoop and Dryad/DryadLINQ.
The RUNES Middleware for Networked Embedded Systems and its Application in a Disaster Management Scenario
Paolo Costa,Geoff Coulson,R. Gold,M. Lad,Cecilia Mascolo,Luca Mottola,Gian Pietro Picco,Thirunavukkarasu Sivaharan,N. Weerasinghe,S. Zachariadis +9 more

TL;DR: This paper separates orthogonal areas of middleware functionality into self-contained components that can be selectively and individually deployed according to current resource constraints and application needs and can be updated at runtime to provide the basis of a highly dynamic and reconfigurable system.
