摘要

A distributed system consisting of symmetric nodes (hosts or computers) that are mutually connected by communication lines and that have identical arrival of jobs is considered. The situation where no node can reduce its mean response time by unilaterally making another decision on forwarding jobs to other nodes is the Nash equilibrium. It is surprising that there exist cases of paradoxical performance degradation where the availability of communication means connecting nodes degrades the mean response time of every node in such a symmetric system. It is notable that there exist cases where paradoxes may bring unlimitedly large degradation of performance.
