Accelerated model for network reliability for M/M/1 model

Testing is a very important way to identify network reliability. However, the mission cycle of networks is usually long. In order to expose network transmission delay failure effectively, reliability testing time is often several times of its mission cycle, otherwise it will bring the problem of both sample size too small and confidence too low. In order to solve this problem, the delay failure mechanism for M/M/1 queuing model was analyzed, the reliability similar criteria was derived based on similarity theory, and the accelerated model was established. This accelerated model was verified based on OPNET simulation platform, and the application method when data arriving intensity changes and does not change was described respectively. The results show that the reliability error for original network under normal stress and similar network under short-term high stress is very small, and the effectiveness of the accelerated model does not change with the failure threshold and stress increase times.
