To conclude, modi?ed design and implementation of a middleware, NICAN, to dynamically supply local network information to distributed scienti?c app- cations was presented. The application provides adaptive capabilities, is n- intrusive, ?exible, easy to use and extensible. The distributed scienti?c appli- tion can use this tool for information collection to its advantage without s- stantial code instrumentation.
