Abstract:
A transparent Optical Packet Switching network designed with Emerging Functions Concept is analyzed as a complex system showing desirable characteristics that emerges from the bottom-up organization. The objective is to describe the Emerging Functions Concept applied to different topologies. The bottom-up organization is obtained from simple rules executed by individual nodes. It is possible to create those simple rules, or fundamental individual functions executed by individual nodes, in order to potentiate scalability, robustness, and other desirable characteristics referred to as Emerging Functions. The scalability is enabled after the avoidance of all long distance signalizations. The robustness emerges from next neighbor signalizations and from the mesh topology with a large number of alternative paths. All emerging functions are better observed for networks with more nodes. The concept is described for the Manhattan Street Network to show the emergence of scalability and robustness. It is also applied to the National Science Foundation Network in order to generalize the procedure showing its applicability to nonsymmetrical and more real topologies. Failure effect segregation is shown for 256 nodes Manhattan Street Network.
