Improving Content Delivery with PaDIS
Found in: IEEE Internet Computing
By Ingmar Poese,Benjamin Frank,Bernhard Ager,Georgios Smaragdakis,Steve Uhlig,Anja Feldmann
Issue Date:May 2012
pp. 46-52
Content-delivery networks (CDNs) originate a large fraction of Internet traffic; yet, due to how CDNs often perform traffic optimization, users aren't always assigned to the best servers for end-user performance. To improve user assignment of CDNs, the aut...
Distributed Network Formation for n-Way Broadcast Applications
Found in: IEEE Transactions on Parallel and Distributed Systems
By Georgios Smaragdakis, Nikolaos Laoutaris, Pietro Michiardi, Azer Bestavros, John W. Byers, Mema Roussopoulos
Issue Date:October 2010
pp. 1427-1441
In an n-way broadcast application, each one of n overlay nodes wants to push its own distinct large data file to all other n-1 destinations as well as download their respective data files. BitTorrent-like swarming protocols are ideal choices for handling s...
Distributed Selfish Caching
Found in: IEEE Transactions on Parallel and Distributed Systems
By Nikolaos Laoutaris, Georgios Smaragdakis, Azer Bestavros, Ibrahim Matta, Ioannis Stavrakakis
Issue Date:October 2007
pp. 1361-1376
Although cooperation generally increases the amount of resources available to a community of nodes, thus improving individual and collective performance, it also allows for the appearance of potential mistreatment problems through the exposition of one nod...
PaDIS emulator: an emulator to evaluate CDN-ISP collaboration
Found in: Proceedings of the ACM SIGCOMM 2012 conference on Applications, technologies, architectures, and protocols for computer communication (SIGCOMM '12)
By Benjamin Frank, Georgios Smaragdakis, Ingmar Poese, Niklas Semmler, Simon Knight
Issue Date:August 2012
pp. 81-82
We present PaDIS Emulator, a fully automated platform to evaluate CDN-ISP collaboration for better content delivery, traffic engineering, and cost reduction. The PaDIS Emulator enables researchers as well as CDN and ISP operators to evaluate the benefits o...
Improving content delivery using provider-aided distance information
Found in: Proceedings of the 10th annual conference on Internet measurement (IMC '10)
By Anja Feldmann, Benjamin Frank, Bernhard Ager, Georgios Smaragdakis, Ingmar Poese
Issue Date:November 2010
pp. 22-34
Content delivery systems constitute a major portion of today's Internet traffic. While they are a good source of revenue for Internet Service Providers (ISPs), the huge volume of content delivery traffic also poses a significant burden and traffic engineer...
Comparing DNS resolvers in the wild
Found in: Proceedings of the 10th annual conference on Internet measurement (IMC '10)
By Bernhard Ager, Georgios Smaragdakis, Steve Uhlig, Wolfgang Muhlbauer
Issue Date:November 2010
pp. 15-21
The Domain Name System (DNS) is a fundamental building block of the Internet. Today, the performance of more and more applications depend not only on the responsiveness of DNS, but also the exact answer returned by the queried DNS resolver, e.g., for Conte...
Delay tolerant bulk data transfers on the internet
Found in: Proceedings of the eleventh international joint conference on Measurement and modeling of computer systems (SIGMETRICS '09)
By Georgios Smaragdakis, Nikolaos Laoutaris, Pablo Rodriguez, Ravi Sundaram
Issue Date:June 2009
pp. 159-162
Many emerging scientific and industrial applications require transferring multiple Tbytes of data on a daily basis. Examples include pushing scientific data from particle accelerators/colliders to laboratories around the world, synchronizing data-centers a...
EGOIST: overlay routing using selfish neighbor selection
Found in: Proceedings of the 2008 ACM CoNEXT Conference (CONEXT '08)
By Azer Bestavros, Georgios Smaragdakis, John W. Byers, Mema Roussopoulos, Nikolaos Laoutaris, Vassilis Lekakis
Issue Date:December 2008
pp. 1-12
A foundational issue underlying many overlay network applications ranging from routing to peer-to-peer file sharing is that of connectivity management, i.e., folding new arrivals into an existing overlay, and re-wiring to cope with changing network conditi...
