Dynamic Reconstruction of Multiple Overlay Network for Next Generation Network Services with Distributed Components

Abstract

Because of rapid improvement in information and network technologies, many kinds of network services are created. In this paper, the concept of a new service platform is presented. Services are organized by components, and replications of components are distributed to many computers. Thanks to these replications, users can continue services by using another component as a substitute in case of failure. It is necessary to ask another component to find a substitute when a component fails. However, depending on which component to ask, the original version of the proposed method has a possibility to find only low-performance components. It is caused by constructing overlay network only once and keeping it as it is. We propose a new dynamic reconstruction method for overlay networks. Simulation experiments show how proposed method improves performance of our framework.
