Fault model of foreign function interface across different domains

Flexibility of software is a key part of resilient software. Scripting technology will help us to improve the software flexibility from the development phase to the operational phase. We focus on the interaction between components, since the nature of scripting language serves as a glue for different components. Existing scripting languages; however, have little concern about this interaction. Our key idea is automated tracking of interactions between components. Component interaction can be observed at the component service interface for external components. Therefore, we propose to include an observation point at the service interface into the scripting language.
