在本文中，我们提出了一种新的应用级多播协议，称为 Emma（多方应用的最终用户多播），适用于在终端主机之间实时交换多个视频源的通信系统，例如视频会议。 Emma的主要特点是，优先考虑用户赋予的较高优先级的视频源，以在用户级别提供服务质量，并且Emma中的所有操作都以分布式方式完成。我们的实验结果表明，Emma 在覆盖网络上实现了合理的性能，并且用户满意度很高。
In this paper, we present a new application level multicast protocol called Emma (end-user multicast for multi-party applications) suitable for communication systems where multiple video sources are exchanged in real-time among end-hosts, such as video-conferencing. The primal feature of Emma is that video sources with the higher priority given by users are prioritized among others for the provision of quality of service at the user level and that all the operations in Emma are done in a distributed manner. Our experimental results have shown that Emma achieves reasonable performance on overlay networks with high user satisfaction.
