Self-Organization Based Network Architecture for New Generation Networks

An emerging new generation network is requested to accommodate a enormous numbers of nodes with high diversity and a wide variety of traffic and applications. To achieve higher scalability, adaptability, and robustness than ever before, in this paper we present new network architecture composed of self-organizing entities. The architecture consists of the physical network layer, service overlay network layer, and common network layer mediating them. All network entities, i.e. nodes and networks, behave in a self-organizing manner, where the global behavior emerges through their operation on local information and direct and/or indirect mutual interaction. We also allow inter-layer interaction through the common network layer for a network system to be self-organized as a whole and effectively and efficiently react to unexpected failure.
