摘　　要：对光突发交换网络中传统的数据信道调度算法进行了分析。针对其不足之处进行了改进,提出了一种基于突发包计算权值的最小时隙数据信道调度算法。从理论上分析了该算法的优越性,并通过实验仿真对算法的性能进行验证。采用理论估计和现实仿真运算相结合的方法对其分析误差。结果表明该算法在信道利用率、降低突发的丢包率、减小网络的拥塞等方面比传统的数据信道调度算法有了较大的提高。The data channel scheduling algorithm of traditional algorithm in optical burst switch is analyzed.To solve the shortage,a latest available unscheduled channel with smallest void based on calculating coefficient related to burst is presented.The advantages of the algorithm are analyzed in theory,and the performance of the algorithm is validated by simulation.The methods of the combination of theoretical analysis and realized simulation are used to analyze error.The result shows that the algorithm has biggish enhancement than traditional algorithm in channel transport efficiency,reducing burst loss ratio and minishing the congestion in network.
