| Summary: | 碩士 === 國立成功大學 === 電機工程學系碩博士班 === 92 === IEEE 802.17 RPR is a MAN (Metropolitan Area Network) candidate due to its ability to achieve fairness and fast restoration. RPR is a ring network with rate-based control. It is standardized as IEEE 802.17 and several proposals have been made to the IEEE 802.17 working group. This paper investigates the performance impact of TCP with window-based control over RPR network. We propose an analytical model is developed to study TCP performance over RPR rate-based control. Through detailed simulations, the proposed analytical model is shown to be accurate. Furthermore, we can understand that the increase of buffer size can enhance the performance of TCP over RPR. But that is just a negative way in fact. So we propose our enhanced schemes again. The schemes use a concept that some packet should be dropped when the congestion is happened so that the excessive packet loss can be avoided. Therefore, the performance of TCP over RPR is enhanced.
