随机网络演算中的模型转换
On the Model Transform in Stochastic Network Calculus
摘要:
随机网络演算需要特别注意在搜索适当的随机交通到达模型和随机服务模型。必须在性能界限分析的可行性、性能界限的有用性和数值计算的方便性之间进行权衡。从理论上讲,不同业务到达模型之间的转换和不同业务模型之间的转换是可能的。然而,模型变换对性能界限的影响尚未得到彻底的研究。本文旨在研究模型转换的效果,为随机网络演算中的模型选择提供实践指导。
英文摘要:
Stochastic network calculus requires special care in the search of proper stochastic traffic arrival models and stochastic service models. Tradeoff must be considered between the feasibility for the analysis of performance bounds, the usefulness of performance bounds, and the ease of their numerical calculation. In theory, transform between different traffic arrival models and transform between different service models are possible. Nevertheless, the impact of the model transform on performance bounds has not been thoroughly investigated. This paper is to investigate the effect of the model transform and to provide practical guidance in the model selection in stochastic network calculus.
