Reliability Simulation Evaluation Technology of Network System with Hardware and Software Combined

Abstract

In view of the characteristics of the network system, such as the combination of software and hardware, multi-state, cross-platform, etc., the difficulty of building the test environment, the high test cost, and the difficulty in effectively carrying out the quantitative reliability evaluation, this paper proposes a quantitative reliability evaluation process and method of network system based on discrete event simulation combining software and hardware. According to the characteristics of the network system, a generalized network system reliability simulation evaluation process considering the combination of software and hardware is proposed. Taking two common network system reliability parameters, function availability and task reliability as examples, a generalized discrete event simulation-based network system reliability evaluation method and model are given. Finally, taking a communication system as the object, the simulation evaluation results of the system are given to Verify the feasibility and engineering applicability of the techniques and methods proposed in this paper.
