Reducing costs for end-users of the Internet
Researchers at the Laboratory of Communication Networks have won the best paper award for improving the efficiency of content distribution systems in the Internet. More efficient systems could in turn lead to a decrease of the costs for the end-users of the Internet.
PhD student Valentino Pacifici and Assistant professor György Dán at Communication Networks won the best student paper award at the International Teletraffic Congress for the paper “Selfish Content Replication on Graphs".
“In the paper we address the problem of content placement in computer and communication systems. We propose an efficient algorithm that helps to decrease the cost of storing and accessing contents in a network,” says Valentino Pacifici.
The algorithm could be beneficial for Internet Service Providers who cache contents, for content distribution systems that pre-fetch contents, etc.
“We give directions for the placement of replicas of the content by different actors, assuming that the actors would be willing to cooperate with each other, even though each of them would be interested in decreasing its own cost as much as possible,” explains Pacifici.
The paper was awarded during the 23rd International TeletrafficCongress (ITC 23) in September 2011.
