In this paper, we investigate the global self-aggregation dynamics arising from local decision-based rewiring of an overlay network, used as an abstraction for an autonomic service-oriented architecture.. The Capsule Reviews were compiled by Fairouz Kamareddine. Scalability issues with respect to the key parameters of system size and diversity are extensively discussed. We demonstrate that in this context, an overlay rewiring process based purely on local decisions and interactions can result in efficient load-balancing without central planning. The distribution of optimal strategies on a Pareto front, however, suggests that there may be a ‘best-fit’ optimal strategy.ArrayThe Capsule Reviews are intended to provide a short succinct review of each paper in the issue in order to bring to a wider readership. The outcome of this is a Pareto front of optimal strategies, all of which would satisfy the objectives. Conflicting goals are introduced, in the form of a population of nodes actively seeking to acquire neighbours of a type different from their own, resulting in decreased local homogeneity. Finally, we introduce dynamic goals by making the preferred neighbour type a function of the local characteristics of a simulated workload. Professor Kamareddine is an Associate Editor of The Computer Journal and is based in the Department of Mathematical and Computer Sciences
