摘要
用(σ,ρ,λ)调节器取代(σ,ρ)调节器,在齐次网络中,讨论了当进入网络的信息包的最大长度L>0和信息流的速率函数R(t)∈{0,C}时,任一比特在单个调节转换器中的延迟.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≥ρ*时,任一比特之最大延迟比未调节时要小;而当ρ<ρ*时,最大延迟比未调节时要大.
Substiting the (σ ,ρ,λ) regulator for the ( σ ,ρ) regulator in the homogeneous system, we research the delay of any data bit (supposing L 〉 0, R (t) ∈{0, C), where L is the biggest length of the packet, R ( t ) is multiplexer ( including e. , minimum) ρ such the rate function of traffic flows entering a network ) in a single regulated general MUX and LFCFS MUX). It is shown that there exists an optimal (i. that Dr≥D for ρ*≥ρ and Dr≤D for ρ≥ρ* ,where Dr and D are the worstcase delay bounds regulated by ( σ ,ρ,λ) regulator and not regulated by (σ ,ρ) regulator respectively.
