我们制定了一个扩展虚拟同步模型，该模型定义了分布式系统中多播和广播通信的组通信传输服务。该模型扩展了Isis系统的虚拟同步模型，以支持在分区网络的所有组件中持续运行。扩展虚拟同步的意义在于，在网络分区和合并期间，以及在流程故障和恢复期间，它在系统中所有流程的消息传递和配置更改的传递之间保持一致的关系，并提供定义良好的自传递和故障原子性属性。我们描述了一种实现扩展虚拟同步的算法，并构造了一个将扩展虚拟同步减少为虚拟同步的过滤器
We formulate a model of extended virtual synchrony that defines a group communication transport service for multicast and broadcast communication in a distributed system. The model extends the virtual synchrony model of the Isis system to support continued operation in all components of a partitioned network. The significance of extended virtual synchrony is that, during network partitioning and remerging and during process failure and recovery, it maintains a consistent relationship between the delivery of messages and the delivery of configuration changes across all processes in the system and provides well-defined self-delivery and failure atomicity properties. We describe an algorithm that implements extended virtual synchrony and construct a filter that reduces extended virtual synchrony to virtual synchrony.>
