| Abstract: |
| Common method and corresponding measures used in the optimization of network expansion and estimation of network reliability are discussed. Shortcomings and deficiency of the current technology of optimization and estimation are pointed out. Aiming at the course of expanding network in the form of adding links, a new optimization method based on spanning tree for network expansion is put forward. Moreover, simulation that applying this method to certain network expansion is done. Compared with other existing methods, design of this optimization method is reasonable and its speed of computation is rapid. So it can be effectively applied to actual optimization course of communication networks. |
