研究了分布式多媒体应用中的流协调问题。大多数传输层协议被设计为独立运行，缺乏与其他流共享信息和以各种方式协调数据传输的机制。这种限制在使用两个计算集群之间的大量流的分布式应用中变得有问题，两个计算集群在互联网上共享相同的中间转发路径。在本文中，我们提出了一个开放的体系结构，它支持共享网络状态信息、对等流信息和特定于应用的信息。简单地称为协调协议(CP)，该方案促进了跨属于同一应用的流的网络资源使用的协调，以及帮助其他类型的协调。在3D远程沉浸中的多流环境中，网络信息的跨流一致性大大提高了帧传输的同步性，并最小化了缓冲延迟，从而证明了该方法的有效性。
We consider the problem of flow coordination in distributed multimedia applications. Most transport-level protocols are designed to operate independently and lack mechanisms for sharing information with other flows and coordinating data transport in various ways. This limitation becomes problematic in distributed applications that employ numerous flows between two computing clusters sharing the same intermediary forwarding path across the Internet. In this article, we propose an open architecture that supports the sharing of network state information, peer flow information, and application-specific information. Called simply the coordination protocol (CP), the scheme facilitates coordination of network resource usage across flows belonging to the same application, as well as aiding other types of coordination. The effectiveness of our approach is illustrated in the context of multistreaming in 3D tele-immersion where consistency of network information across flows both greatly improves frame transport synchrony and minimizes buffering delay.
