Bugs in software are inevitable.The study on the networked software abnormal behavior propagation mechanism trigged by bugs provided the way for people to grasp the execution rule and to adopt corresponding pinning measurements.Based on the situation of abnormal behavior propagation at different granularity software entities,three factors----propagation probability,interactive frequency,and connection rate----affecting the abnormal behavior propagation were proposed,and the corresponding definition and calculation method were also investigated.The software abnormal behavior propagation process model was constructed in reference to the compartment model and individual models and three factors mentioned above,which improved model expression ability and enhanced the model competence and accuracy.Then,the abnormal behavior propagation analytical method was applied to the typical networked software system,and the results verified the correctness and feasibility of the propagation mechanism.
