摘要
随着通信技术的发展以及用户带宽需求的迅猛增长,光网络的研究正在不断的向广度和深度延伸。同时光网络的业务在空间和时间分布上都逐渐产生了复杂性。为了更好的理解光网络本身业务的特点,以便进一步改善光网络对业务的传输性能,对光网络业务在时间和空间上的复杂性进行了研究分析,提出了一种基于时空复杂性的光网络业务模型,设计实现了基于时空复杂性的光网络业务发生器TS。实验表明,该业务发生器产生的业务流在空间上产生的拓扑结构符合无标度网络的特征,同时在时间上TS能够对不同的连接产生满足自相似数据流特征的呼叫连接次数,符合实际光网络中的业务特征,能够准确地反映实际光网络的业务需求。
With the development of communications technology and the increase of bandwidth demands, the antenna of optical networks is extending in extent and depth, while the traffic complexity of optical networks is appearing in space and time. In order to make better knowledge of the characteristics of the traffic in optical networks and improve the transmission performance of the service, a research and analysis of optical network traffic in time-space complexity was taken and a novel optical network traffic model was proposed based on time -space complexity, then the traffic generator TS was designed. Experiments show that the traffic flow generated in the space follows the network characteristics of the topological structure with the scaling-free, and in time TS is able to generate different call frequency according to different generated self-similar data flow characteristics, compatible with the actual optical network operational characteristics, to accurately reflect the actual optical network traffic needs.
