A Simple Computational Market for Network Information Services

摘要

Visionary projections of a wide-area network teeming with intelligent agents describe an environment where end-users and their agents can pick and choose among a great variety of potentially valuable information ser-vices. However, neither network capabilities nor users' time and money are infinite. Computational markets provide one type of mechanism for allocating limited resources in such an environment in a distributed, dy-namic way, Moreover, the underlying economic theory provides an analytical framework for predicting aggre-gate behavior and designing individual agents. In this paper, we describe a prototypical computational mar-ket model for information services distributed over a network. Our initial focus is on the economic prob-lem of when and where to establish mirror sites for the more popular information services. Competitive agents choose to set up mirrors based on going prices for network bandwidth, computational resources, and the information service. Depending on the experimen-tal setup, we observed a range of qualitative behaviors.
