摘要:

自稳定是设计应对瞬时故障的容错分布式算法的通用方法。自稳定系统可从任意类型、任意有限数量的瞬时故障中自动恢复,这一特性在组件数量庞大的现代分布式系统中尤为实用。本文提出一种名为R(1)W(1)模型的新型通信与执行模型,其中每个进程可在单一步骤内读写自身及邻居的局部变量。我们在R(1)W(1)模型下针对最大匹配、最小k-支配集和最大k-依赖集问题,提出了自稳定分布式算法。最后,我们提出了一种基于随机距离二局部互斥的示例转换器,可在带同步时钟的同步消息传递模型中模拟为R(1)W(1)模型设计的算法。

英文摘要:

Self-stabilization is a versatile methodology in the design of fault-tolerant distributed algorithms for transient faults. A self-stabilizing system automatically recovers from any kind and any finite number of transient faults. This property is specifically useful in modern distributed systems with a large number of components. In this paper, we propose a new communication and execution model named the R(1)W(1) model in which each process can read and write its own and neighbors' local variables in a single step. We propose self-stabilizing distributed algorithms in the R(1)W(1) model for the problems of maximal matching, minimal k-dominating set and maximal k-dependent set. Finally, we propose an example transformer, based on randomized distance-two local mutual exclusion, to simulate algorithms designed for the R(1)W(1) model in the synchronous message passing model with synchronized clocks.
