Notification-Based QOS Control Protocol for Group Communication

This paper discusses a group communication protocol to exchange multimedia messages in a group of multiple peer processes. Quality of Service (QoS) required by an application has to be supported. In traditional protocols like RTP, a process can reliably deliver messages to one or more than one process. In the group communication, each process sends a message to multiple processes while receiving messages from multiple processes in a group. Due to the limited computation and communication capacity, we cannot adopt traditional one-to-one or one-to-many transmission ways to the group communication. We propose a notification-based data transmission procedure to exchange multimedia messages among multiple processes so as to satisfy QoS requirement.
