A Method for Planning Spare Capacity Based on Virtual Protection Cycles
Hong Wang · 2004
For the purpose of planning spare network resources, based on the sharing link protection in virtual protection cycles and the majorizing criterion of changing the minimum into maximum excess ordering value , this paper proposes a heuristic algorithm for a certain link resources by using step max iteration to find the majorizing solution of the linear planning equation, to determine the sub-optimum protection cycles of the network where 100% fault protection can be carried out. Simulation results show that the set of virtual protection cycles can be obtained fast by using the proposed algorithm, and the spare network resource can be planned in majorization.
