Abstract

A very large class of access control strategies is proposed and studied for token passing systems, generalized from the timer-based approach. The idea is to assign transmission quotas dependent on past service times to control the token cycles dynamically while utilizing the token channel efficiently. The dynamics inherent in the control scheme are identified as an important issue and, under heavy load and a few other assumptions, it is shown that the proposed strategies have stable dynamics. Furthermore, the ability of the proposed strategies to control the token cycles is demonstrated. Theoretical results are derived, followed by a thorough discussion on the crucial properties of the new strategies.<>
令牌传递系统的通用访问控制策略
在基于定时器的方法的基础上,提出并研究了一大类令牌传递系统的访问控制策略。其思想是根据过去的服务时间分配传输配额,以动态地控制令牌周期,同时有效地利用令牌通道。控制方案中固有的动力学是一个重要的问题,并且在重载和其他一些假设下,表明所提出的策略具有稳定的动力学。此外,还证明了所提出的策略控制令牌周期的能力。推导了理论结果,然后对新策略的关键特性进行了深入的讨论。
