Building self-maintained overlay networks for message routing has recently attracted significant research interest [5–9]. All suggested solutions have a common goal: To build and maintain structures (routing tables) that can be used to route messages. Several of the proposed algorithms focus on efficiency of bandwidth usage. However, their behavior is uncertain in the presence of highly dynamic environments, or serious disasters (i.e. half of the nodes crashing). In this paper we present an alternative approach to managing routing tables for peer-to-peer routing overlay networks, based on the Newscast epidemic protocol [1]. We substantiate our claims by presenting experimental results. We, therefore, demonstrate the potential of the Newscast epidemic protocol to create highly robust, self-administered overlay networks, able to sustain and adapt fast to severe network changes.
