Reliability Evaluation Method of DDS-based Distributed System

This paper proposes a new reliability evaluation method for effective evaluation of the reliability of DDS-based distributed system according to the characteristics of data publish/subscribe in the system. Firstly it introduces the necessity of evaluation of the reliability of DDS-based distributed system, and points out the shortcomings of reliability evaluation method of the traditional software system. Puts a new reliability evaluation method which is based on the traditional method Considered the complexity of component interaction by combining the characteristics of data publish/subscribe in the system.Finally, this paper proves the correctness of the method by comparing the verification examples.
