Barabasi-Albert网络上优先次近邻路由流量模型的临界包注入率

On The Critical Packet Injection Rate Of A Preferential Next-Nearest Neighbor Routing Traffic Model On Barabasi-Albert Networks

H. F. Chau, H. Y. Chan, F. K. Chow

摘要:

最近,Yin等人[Eur. Phys.J.B49,205(2006)]提出了一种有效的小世界网络流量模型,该模型使用优先次近邻路由策略和路径迭代避免(PIA)规则来研究互联网的拥塞过渡。在这里,我们研究他们的模型没有PIA规则的平均场分析,仔细划分成两种类型的消息包。然后,我们认为,我们的平均场分析也适用于PIA规则的存在下,在网络中的大量节点的限制。我们的分析给出了一个明确的表达的关键数据包注入率$R_c$作为一个偏置参数的路由策略$α$在他们的模型有或没有PIA规则的函数。特别地,我们预测在$α$的某个值处$R_c$的突然变化。这些预测与我们广泛的计算机模拟相当吻合。

英文摘要:

Recently, Yin et al. [Eur. Phys. J. B 49, 205 (2006)] introduced an efficient small-world network traffic model using preferential next-nearest neighbor routing strategy with the so-called path iteration avoidance (PIA) rule to study the jamming transition of internet. Here we study their model without PIA rule by a mean-field analysis which carefully divides the message packets into two types. Then, we argue that our mean-field analysis is also applicable in the presence of PIA rule in the limit of a large number of nodes in the network. Our analysis gives an explicit expression of the critical packet injection rate $R_c$ as a function of a bias parameter of the routing strategy $α$ in their model with or without PIA rule. In particular, we predict a sudden change in $R_c$ at a certain value of $α$. These predictions agree quite well with our extensive computer simulations.
