Replicated Processes in Manetho
This paper presents the processreplication protocol of Manetho, a system whose goal is to provide efficient, applicationtransparent fault tolerance to longrunning distributed computations. Manetho uses a new negative acknowledgment multicast protocol to enforce the same receipt order of application messages among all replicas of a process. The protocol depends on a combination of antecedence graph maintenance, a form of senderbased message logging, and the fact that the receivers of each multicast execute the same deterministic program. This combination allows our protocol to avoid the delay in application message delivery that is common in exist ing negativeacknowledgment multicast protocols, without giving up the advantage of requiring only a small number of control messages.
