碩士 === 國立臺灣大學 === 資訊工程研究所 === 84 === The paper will discuss how to record the exection progress of an application and reproduce it. The recording and reproducing of an application exection progress can be applied to the records of conference systems, virtual classroom and the help of an software. The recording and reproducing system is composed of three components : the recording tool, the reproducing tool and the recorded file. The recording tool is responsible for the execution progress of the application and saving to the file. After that, the reproducing tool reads the data of the recorded file and reproducing the progress. An application will invoke the system calls, send and process messages. The system calls and messages are the object to be recorded. The recording process consists of many steps including interception, analysis, packet and save. The reproducing process includes retrieve, analysis, packet and invokation. There are many issues about the system such as resource process, choice of inteerception point, time simulation and reproducing direction. In addition, the of the system and the size of recorded file are the important consideration of the system. In the future, the recorded content may be developed into Script to provide the editing of the application execution progress.
