碩士 === 國立雲林科技大學 === 資訊工程研究所 === 94 === In recent years, the development of internet has brought huge demands on bandwidth. Multimedia applications and point-to-point traffic are also applied more frequently. All these factors make ATM-based or SONET/ADH-based Metropolitan Area Networks hard to fully load bandwidth. For this reason, IEEE has gathered a task group to formulate a new and more efficient MANs standard. After many researches and improvements, the new standard, IEEE 802.17 Resilient Packet Rings (RPR), was done in 2004. This standard is for the purpose of commercial metropolitan area networks, so it specially concerns about efficiency and fairness. There are many mechanisms, such as shaper, spatial reuse mechanism and fairness mechanism, are introduced to achieve high efficiency and better fair transmission. All these improvements make the new standard well suitable to handle the mission of metropolitan area network transmission. In this thesis, we not only describe the idea and structure of RPR but also build a simulation model to emulate this standard. With this simulation model, we have done a series of analyses about transmission delay, jitter, efficiency and fairness algorithm under different traffic types. We also have got a lot of data and analysis results. In the results, we can see that the QoS mentioned in the standard is efficiently achieved. However, there are still many topics, like the stability of bandwidth and efficiency of fairness algorithms, needed to be improved. In order to achieve high efficiency and transmission quality, researches on these issues are important in the future.
