The main goal of the project is to evaluate a
decentralized economic control andcoordination mechanism, the Catallaxy
paradigm, for the decentralized control of dynamic application layer
networks.
The project partners will compare the performance of
the decentrally operated dynamic application network with a baseline
system consisting of a centrally controlled application network, to
assess the feasibility of the approach.
Application layer networks such as content distribution networks or
peer-to-peer networks are software architectures that allow the
provisioning of services requiring large amount of resources, which can
be obtained from computing systems connected over simple communication
infrastructures such as the Internet.
Managing application layer networks is a general task of
decentralized resource allocation, for which economic principles are
applicable.
The project pursued here combines economic and computer science
research to provide new coordination mechanisms for large-scale
computer networks.
In the application layer network context of GRID networks, existing
systems such as Darwin, Globus or Radar already employ a centralized
auctioneer instance somewhere in the network for service control and
resource allocation. This centralized approach has several drawbacks,
some of which can in our view not be solved by incremental research.
Considering this, the project partners propose an assessment of a
fully decentralized economic approach to resource allocation, the
Catallaxy paradigm, for managing distributed application layer
networks. The experiment will consist of the simulation of an
application layer network being operated under the catallaxy paradigm
and a baseline centralized system. The simulation results will
determine how the system behaves under both paradigms.
