| 内容記述 | Optical Burst Switching (OBS) has been proposed as a promising switching <br />technology for the next generation of optical transport network. In this dissertation, <br />we address the issue how to provide QoS control and improve performance in OBS <br />networks . <br /> In order to provide proportional differentiated services without or with absolute <br />constraints in bufferless OBS networks, a Dynamic Wavelength Selection (DWS) <br />scheme is introduced to assign more and longer periods of wavelengths to higher <br />priority classes dynamically and efficiently due to wavelength-sharing. The inte- <br />gration of DWS scheme and another proposed Delayed Burst Assignment (DBA) <br />scheme improves the burst loss performance by giving the burst head packet (BHP) <br />two opportunities of scheduling its data burst (DB). <br /> Furthermore, we propose two novel burst assembly algorithms with traMc shap- <br />ing functions to reduce the variance of assembled traffc and improve the burst <br />loss performance, which are named advanced timer-based and sliding window-based <br />assembly algorithms. <br /> Finally, an edge buffering based OBS layer fast error recovery scheme is pro-- <br />posed to improve the TCP performance over OBS networks, in which lost bursts are <br />retransmitted at edge nodes without being reassembled. <br /> In general, all the proposed schemes solve many of the fundamental issues faced <br />by optical burst switching networks, thereby making OBS more practical and efii- <br />cient in the near future.<br /> | |||||
