提案：0073085题目：基于交换机的网络中的高效组播通信提高服务质量组播涉及将信息从一个源发送到多个目的，是高性能网络的需求。预计多播将越来越多地用于支持各种交互式应用，如视频点播、电话会议、网络服务器和互联网上的电子商务。其中许多应用程序不仅需要多播功能，还需要可预测的性能，例如有保证的多播延迟和带宽，称为服务质量（QoS）。本研究的目的是在组播网络的基础上设计一种具有QoS功能的组播架构，并内置QoS功能来支持组播通信。具体来说，研究的重点是：(1)设计具有更好的QoS功能和更低的网络成本的基本构件组播网络；(2)建立具有统计qos能力的组播架构的性能指标分析模型；(3)研究针对不同QoS要求的高效组播调度方案；(4)建立验证理论结果的仿真工具，并将其提供给研究社区和系统设计者。本研究结合算法、概率、组合和模拟技术进行综合研究。该研究对可扩展和高性能并行/分布式计算具有重要影响，因为有效支持组播通信可以显着降低通信延迟，并简化众多并行/分布式应用程序的设计和实现。

Proposal: 0073085Title: Efficient Multicast Communication in Switch-Based Networks for Quality of ServicePI: Yuanyuan YangMulticast involves transmitting information from a source to multiple destinations, and is a requirement in high-performance networks. It is projected that multicast will be increasingly used to support various interactive applications such as video-on-demand, teleconferencing, web servers and E-commerce on the Internet. Many of these applications require not only multicast capability but also predictable performance, such as guaranteed multicast latency and bandwidth, called quality-of-service (QoS). The objective of this research is to design a QoS capable multicast architecture based on multicast networks with built-in QoS functions to support multicast communication. Specially, the research focuses on:(1) design of basic building-block multicast networks with better QoS functions and lower network cost;(2) establishing analytical models on performance metrics of statistical QoS-capable multicast architectures;(3) study of efficient schemes to schedule multicast for different QoS requirements;(4) building simulation tools for validating theoretical results, and making them available to research community and system designers.This research combines algorithmic, probabilistic, combinatorial, and simulation techniques to conduct comprehensive studies. The proposed research has a significant impact on scalable and high-performance parallel/distributed computing as efficient support for multicast communication can significantly reduce the communication latency and simplify the design and implementation of numerous parallel/distributed applications.
