Optimized Ring Identification for an Arbitrary Network Topology and Traffic Matrix
ReferenceProceedings of Workshop on All Optical Networks (WAON) 2001, June 2001.
AbstractAn optimized algorithm is presented to embed a mesh of rings network in an arbitrary network topology to provide the necessary transport capacity for a given traffic pattern. The network can be characterized by a three-layer model. The first layer defines the ring configuration, the second the connection allocation and the third the connections among the rings. Rings are constructed systematically from faces. It is assumed that a ring provides a full-meshed network with a certain capacity between every node pair. Simulated annealing (SA) is used to optimize the mapping to best fit the traffic demands. For the objective function certain parameters can be considered. It is possible to incorporate boundary conditions, e.g. the maximum number of nodes in a ring in this function. The algorithm is tested on the basis of the COST~239 Pan-European case study as an example.
