Abstract

A large-scale network like the Internet is composed of various types of communication channels. Here, each communication channel supports quality of service (QoS) which may be different from others. In group communication, each process sends a message to multiple processes while receiving messages from multiple processes. In addition, messages are required to be causally delivered. In order to realize the atomic and ordered delivery of messages, even if a process with enough QoS channel receives messages, the process has to wait to deliver the messages until another process with lower QoS channel receives the messages. Thus, multimedia data cannot be delivered to processes so as to satisfy the real-time constraint if a slower process is included in a group. In this paper, we discuss group communication protocols by which multimedia messages can be delivered to a process with same time constraint properties which satisfy QoS requirements of multimedia messages.

群通信中基于qos的同步/异步数据传输模型

像Internet这样的大型网络是由各种通信通道组成的。在这里，每个通信通道都支持不同于其他通道的服务质量(QoS)。在组通信中，每个进程向多个进程发送消息，同时接收来自多个进程的消息。此外，消息需要以因果关系的方式传递。为了实现消息的原子和有序传递，即使具有足够QoS通道的进程接收到消息，该进程也必须等待具有较低QoS通道的另一个进程接收到消息后才能交付消息。因此，如果组中包含较慢的进程，则无法将多媒体数据传递给进程以满足实时性约束。本文讨论了在满足多媒体消息QoS要求的情况下，将多媒体消息传递到具有相同时间约束属性的进程中的组通信协议。
