【Abstract】 This paper introduced reliability evaluation of time-constrained distributed software (TCDS), and expatiates on the evaluation algorithm of response time based on linear file transmission path. This system can simulate distributed software under different topologies by changing some factors, such as the topology structure, capability and reliability of link, and the file set needed for the execution of each program. This evaluation algorithm of response time decreases the time cost and improves the efficiency of the whole reliability evaluation of this software.更多还原
