Abstract:
Aiming to contribute to a solution for the number of nodes scalability problem, a transparent Optical Packet Switching (OPS) network is treated in a new approach that considers the network as a complex system. This treatment allowed the investigation of a network based on large number of autonomous OPS nodes connected in a mesh topology. The network operates in a bottom-up organization and the long distance signalization, one of the main factors responsible for the number of nodes limitation, is avoided and the scalability is enabled. Desirable characteristics (scalability, traffic organization, protection, restoration, etc.) result from simple rules executed by individual nodes. All those characteristics are referred to as Emerging Functions. It is possible to create those simple rules, or fundamental individual functions executed by individual nodes, in order to potentiate those Emerging Functions. As an example, a set of node interactions with their next neighbors is described. That will result in a Protection Emerging Function able to maintain the network operation after failure and to confine the network degradation just around the failure position. That segregation of the failure effects represents a new feature that could be observed due to the new approach.
