Challenging issues in dynamic reconfiguration of telecommunication networks

For the last quarter of a century understanding of the nature of telecommunication network traffic has been considered as an important research topic. Any well-designed recovery strategy has to take into account the different resilience requirements of the single traffic flows in order to avoid excessive usage of bandwidth for standby links. Here we discuss the issues of a reconfiguration procedure in order to perform network recovery in the case of any failure scenario in the telecommunication networks. We explain the complexities arising in the real life application and propose an optimization technique in order to minimize the size of the optimization problem in the process of reconfiguration. Our suggestion to achieve this is to find the minimal sub-graph surrounding the failure region that contains the required unused capacity to perform network recovery task
