Abstract: A new method was proposed to evaluate the survivability of the software system
based on the calling structure of the software. Firstly, the interactions among the components of
the software were obtained using the static lexical analysis technology and dynamic monitoring
of the AOP (Aspect ORIENTED PROGRAmming). The calling network was constructed to model
the calling structure of the software. Secondly, a component failure simulation method was
proposed by removing the nodes and edges corresponding to the selected components from the
calling network. The residual calling network was considered as the software calling structure
when the components are disabled. Then, the survivability coefficient was presented to measure
the survivability of the software system, the proportion of the biggest connected subgraph of the
residual network compared to the original call network diagram. In the experiments, nine open
source software projects were selected to compare their survivability, and 20 versions of Struts
(J2EE framework) were chosen to investigate the changes of the software survivability during
their updating. Our evaluation concurs with the intuition that minor upgrades, aimed at fixing
bugs and adding minor functionality quickly, reduce software survivability, whereas major
upgrades, which normally clean up messy code and re-construct the software, improve software
quality.
