中文摘要: 在多级网络模型中,用(σ,ρ,λ)调节器取代(σ,ρ)调节器,讨论了当进入网络的信息包的最大长度L大于零、信息流的速率函数R(t)为0或者C时,任一比特在多级网络模型中的延迟.证明了存在一个最优值(也是最小值)ρ*,当信息流平均速率ρ不大于ρ*时,任一比特的最大延迟比未调节时要大;而当ρ大于ρ*时,最大延迟比未调节时要小.
Abstract:In multistage network model,with the (σ,ρ,λ) regulator instead of (σ,ρ) regulator,the delay of any data bit is analyzed,supposing L is bigger than zero and R(t)is either zero or "c",where L is the biggest length of the packet,R(t) is the rate function of traffic flows entering a network.It is shown that there exists an optimal (i.e.,minimum) ρ* such that Dr≥D for ρ*>ρ and Dr≤D for ρ≥ρ*,where Dr and D are the worst-case delay bounds regulated by (σ,ρ,λ) regulator and by (σ,ρ) regulator respectively.
