Abstract:

This paper studies a single-server queueing system with deterministic service time in which arrivals are regulated by the leaky-bucket mechanism. This paper intends to improve quantitative understanding of the effects of arrival rate and burstiness on the average delay of queueing systems. The study is directed toward identifying the worst traffic of arrivals allowed by the leaky-bucket regulation and clarifying the effects of the leaky bucket parameters (which represent the arrival rate and burstiness) on the average queueing delay. The arrival traffic that maximizes the average queueing delay is characterized as the repetition of the following three phases: bulky arrival, greedy arrival for a specified length of interval, and then no arrival till the token bucket is full. The average queueing delay for the worst traffic is expressed as a function of the leaky bucket parameters.
