Operational Network Topology Reeonfiguration Based on Foeus of Guarantee

Network topology reconfiguration is critical for transmission efficiency as well as operational efficiency in operational process. Currently, most researchers pay much attention to the reconfiguration problem caused by adding or deleting nodes or links. In this paper, we propose a novel approach of operational network topology reconfiguration based on Focus of Guarantee (FoG) model, aiming to meet the need of precise operational network organizing. We firstly introduce the FoG concept model and analyze the relationship between FoG and network topology reconfiguration. Afterwards, the optimal problem of network topology reconfiguration is discussed on the basis of traffic characteristic constraints extracted from FoG model. Experiment results show that such FoG based method effectively improves the transmission efficiency of reconstructed operational network.
