碩士 === 國立中央大學 === 資訊管理研究所 === 94 === The most traditional approaches to network optimization focuses on bringing new or improved capabilities to target functional areas of network operations. The goal is to boost the unit’s efficiency and effectiveness. Basically, there are three different approaches proposed to help in designing adaptive multimedia systems for heterogeneous devices: server-side adaptation, proxy-based adaptation, and service-based adaptation. Though there are a variety of approaches being proposed, evaluating content adaptation approaches is still lacking. This study shows a simulation effort to evaluate and compare the differences among those three kinds of content adaptation approaches. A 2 by 4 factorial design simulation is implemented to test the effects of five different influential factors within the network: 1) client’s request rate, 2) number of adaptation sub-process, 3) process time of an adaptation sub-process, and 4) network latency time. The result shows some valuable information and could be used as a key reference for the optimization of content adaptation network.
