Abstract

Distributed application systems require group communications among multiple processes. In the group communication, it is important to discuss in what order each process in the group can receive messages. The paper presents a causally ordering group communication (CO) protocol which provides the same causal ordering of messages for all the processes in the group. In the CO protocol, the messages received are causally ordered by using the sequence numbers of the messages. The CO protocol is based on the fully distributed control scheme, i.e. no master controller, and uses high-speed networks where each process may fail to receive messages due to the buffer overrun. Furthermore, the CO protocol provides asynchronous data transmission for multiple processes in the group.
随机排序组通信协议
分布式应用系统需要在多个进程之间进行组通信。在组通信中,讨论组中每个进程接收消息的顺序是很重要的。提出了一种为组内所有进程提供相同的消息因果排序的因果排序组通信(CO)协议。在CO协议中,通过使用消息的序列号对接收到的消息进行因果排序。CO协议基于完全分布式控制方案,即没有主控制器,并使用高速网络,每个进程可能由于缓冲区溢出而无法接收消息。此外,CO协议为组中的多个进程提供异步数据传输。
