Abstract: A hierarchical distributed mutual exclusion algorithm is proposed to reduce the complexity when a node wants to get the permission of a distributed system to access a multi-replica object. This method improves the tolerance-default of the system and makes the algorithm become more steady. And it can reduce the response time of the system
