具有自适应服务机制的轮询系统的稳定性

On the Stability of a Polling System with an Adaptive Service Mechanism

Natalia Chernova, Sergey Foss, Bara Kim

摘要:

我们考虑一个单服务器的循环轮询系统与三个队列的服务器遵循自适应规则:如果它发现一个队列空在一个给定的周期,它决定不访问该队列在下一个周期。在有限的服务政策的情况下,我们证明了稳定性和不稳定性的结果在某些条件下,这是充分的,但不是必要的,在一般情况下。然后我们讨论了确定有限服务规则模型的精确稳定区域的公开问题:我们猜想稳定的一个充要条件可能依赖于原始序列的整个分布,并通过例子说明。我们结束了一节的轮询系统的稳定性分析,无论是门控或详尽的服务纪律的文件。

英文摘要:

We consider a single-server cyclic polling system with three queues where the server follows an adaptive rule: if it finds one of queues empty in a given cycle, it decides not to visit that queue in the next cycle. In the case of limited service policies, we prove stability and instability results under some conditions which are sufficient but not necessary, in general. Then we discuss open problems with identifying the exact stability region for models with limited service disciplines: we conjecture that a necessary and sufficient condition for the stability may depend on the whole distributions of the primitive sequences, and illustrate that by examples. We conclude the paper with a section on the stability analysis of a polling system with either gated or exhaustive service disciplines.
