Abstract: QoS is a natural requirement of the development of optical network. The presented algorithm of traffic grooming attaches too much importance to the usage rate of bandwidth, compared with such few studies on other QoS indices like delay, packet loss and throughput. On the basis of existing theories, a new routing technology is put forward in this paper with a comprehensive consideration of other QoS indices. The result of tests proves that LSP better meets the transmission request of QoS.

摘要： 满足数据业务QoS是网络发展的必然要求，现行数据疏导技术更多考虑是提高带宽利用率，对QoS中其他指标如时延、丢包、吞吐量等研究甚少。提出了基于QoS的路由算法是在现有理论基础上综合考虑了QoS的其他指标。算法测试结果表明，主/备用LSP的路由选择更好地满足了数据业务的传输需求。
