Research on statistical network calculus-based bandwidth demand of dual leaky bucket models

为满足双漏桶模型的业务流量需求,提出一种基于统计网络演算理论的带宽需求研究方案。该方案利用统计网络演算在分析业务时延性能方面的优势,由时延与带宽的关系建立出双漏桶模型业务流带宽需求的统计模型,对业务带宽需求进行了研究分析。数值分析结果表明了该方案的有效性和优越性,对网络合理分配带宽资源有一定的参考意义。

In order to meet the demand of dual leaky bucket models for traffic flow, this paper proposes a bandwidth demand re-search program based on statistical network calculus theory. Making use of the advantages of the statistical network calculus in analyzing traffic delay performance, this program establishes a statistical model for the bandwidth demand of the dual leaky bucket model traffic flow on the basis of the relationship between delay and bandwidth and conducts in-depth research and anal- ysis on traffic bandwidth demand. Numerical analysis results show that this program is effective and superior and has much value of reference for rational allocation of network bandwidth resource.
