Abstract

Because the computational complexity of high usability analysis is too high when selecting the routing protocol in the bank network plan, a simple measurement method of high usability for banks is proposed to solve this problem in the article. First, establish a simulation environment which is close to the real network of banks to offer the measurement environment and data. Second, based on the theoretical comparison of LSRP and DVRP, establish the simple simulation measurement algorithm by Shannon’s information entropy theory. Finally, evaluate the degree of high usability of LSRP and DVRP in the bank network by this algorithm. The result of simulation shows that (1) the simulation is close to the periodic rule of the statistical data group in real environment, (2) the deviation ratio is less than 0.1, and (3) the covariance is unequal to 0. And the result indicates that the simulation is connected with the real environment and both are very close, and the simulation environment can offer effective data. The computation result of the simple simulation measurement algorithm shows that the time cost differences of LSRP and DVRP exist in the period of fault recovering, which indicates the simple measurement algorithm is effective.
