Abstract

In this paper we study asynchronous networks, in which processors may fail and recover several times during an execution. Upon recovery a processor rejoins the execution as a passive processor, with all variables initialized, except for a fault flag, which is updated by the system. In addition to the regular communication links connecting pairs of processors, the processors are connected by a unidirectional ring of communication links, such that upon a failure of a processor all of the processor's incoming messages are transferred to the outgoing link belonging to this ring. We present a general transformation, that modifies any algorithm, that is designed for an ordinary fault-free asynchronous network, to run on such networks.
