摘要:

在这篇文章中,我们研究了无标度网络上的人工流量模型。该算法不采用最短路径的选路策略,而是采用广义选路算法来提高运输吞吐量,该算法以自由流阶段和拥挤阶段的分界点的值来衡量。通过去趋势波动分析,我们发现,在临界点附近的业务速率波动的功率谱表现出$1/f$型标度。仿真结果与实验数据吻合较好,因此该模型有助于理解网络流量的内在机制。

英文摘要:

In this article, we investigate an artificial traffic model on scale-free networks. Instead of using the routing strategy of the shortest path, a generalized routing algorithm is introduced to improve the transportation throughput, which is measured by the value of the critical point disjoining the free-flow phase and the congested phase. By using the detrended fluctuation analysis, we found that the traffic rate fluctuation near the critical point exhibits the $1/f$-type scaling in the power spectrum. The simulation results agree very well with the empirical data, thus the present model may contribute to the understanding of the underlying mechanism of network traffics.
