Federation of Virtualized Infrastructures: Sharing the Value of Diversity

November 16, 2010
Time: 2:00pm-3:00pm
EE Conference Room (13th floor Mudd)
Hosted by: Columbia University Joint CS/EE Networking Seminar Series
Speaker: Dr. Panayotis Antoniadis (Pierre & Marie Curie University/LIP6, Paris, France)


By federating virtualized computing and network resources one can significantly increase their value thanks to gains from statistical multiplexing and increases in resource diversity (more diverse locations, technologies, etc.). Successful federation depends upon resource providers being able to agree on policies: how to share the profit generated by external customers and how to allocate the resources contributed by the federation participants to their affiliated users. This seminar analyzes a novel economic model of federation, which captures an important characteristic of virtualized infrastructures: the value of diversity [1]. Our first results indicate that the correct characterization of the expected type and volume of demand and the use of sophisticated profit sharing mechanisms is necessary for implementing theoretically justified federation policies in this context. To this end, I will motivate the use of the Shapley value as a means for the participating organizations to share the value of federation and show how this approach can help in the design of realistic policies that encourage infrastructure owners to federate.

Speaker Biography

Panayotis Antoniadis is a researcher at UMPC Sorbonnes Universités (Paris 6). His main research contributions are in the economic modelling and incentive mechanisms for peer-to-peer systems and in distributed scheduling algorithms for high-speed switches. He is currently working on resource management mechanisms and federation policies for shared network facilities (IST project Onelab). He is also exploring the role of social software, wireless networks and peer-to-peer systems on the design of sustainable hybrid neighborhood communities (project nethood). He received his B.Sc. and M.Sc. degree from the Computer Science Department of University of Crete in 1998 and 2000 respectively and his Ph.D degree from the Department of Informatics of Athens University of Economics and Business in 2006.
