讨论了利用不可靠广播通信服务为分布式系统中的多个实体提供可靠广播通信的方法。在真实的分布式应用中，每个实体只将每个PDU（协议数据单元）发送给子集，而不是所有实体，并且每个实体只接收某个实体以相同的发送顺序发送到它的PDU。这样的广播服务被命名为SPO服务（对pdu进行选择性部分排序的服务）。讨论了在pdu丢失的情况下，如何利用不可靠的广播网络为实体提供SPO服务。在设计和实现分布式系统（如分布式数据库系统）时，SPO服务是一个非常有用的工具
Methods to provide reliable broadcast communication for multiple entities in distributed systems by using unreliable broadcast communication services are discussed. In real distributed applications, each entity sends every PDU (protocol data unit) to only the subset, rather than all the entities, and each entity receives only PDUs destined to it from some entity in the same order as they were sent. Such a broadcast service is named an SPO service (service for selectively partially ordering PDUs). How to design a protocol which provides the SPO service for entities by using unreliable broadcast networks in the presence of lost PDUs is discussed. The SPO service can be a useful facility in designing and implementing distributed systems like distributed database systems.<<ETX>>
