项目摘要

Any time an application uses the Internet, behind the scenes, rate control algorithms decide how quickly to transmit data. These algorithms have a critical task; sending too slowly causes delay or reduced video quality, and sending too quickly causes congestion that impacts both the sender and other users. Rate control is a persistent challenge in networking, as it has to deal with a wide range of dynamic environments while making millisecond-level decisions with limited information. This project is developing new approaches to rate control based on an area of machine learning known as reinforcement learning, leading to potential improvements in performance and functionality.At a high level, the project seeks to develop a fundamental understanding of the use of reinforcement learning for rate control, and apply that understanding to the areas of adaptive bitrate (ABR) video as commonly used in modern web-based video, and to transport layer congestion control, such as the Transmission Control Protocol (TCP). The work will begin with algorithmic foundations by exploring what level of complexity of learning algorithm (ranging from bandit algorithms to deep neural networks) is necessary to achieve high performance. Next, the project will broaden the semantics of inputs and outputs of rate control, including a scavenger rate control protocol and an improved multipath TCP. Finally, the project will use novel automated methods to improve the robustness of rate control protocols in unexpected environments.The results of this project can offer significant performance improvement for deployed protocols, which is of increasing need as modern and emerging applications have ever more demanding network requirements. For example, low latency communication and high quality real-time video are valuable for interactive conferencing, augmented and virtual reality, Internet of Things, edge computing, and more. The project also plans to provide research opportunities for underrepresented groups.The results of this project, including papers and open-source code, will be available at http://pccproject.net and at the code repository, https://github.com/PCCprojectThis award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

任何时候，应用程序使用互联网，在幕后，速率控制算法决定如何快速传输数据。这些算法有一个关键的任务;发送太慢会导致延迟或降低视频质量，发送太快会导致拥塞，影响发送者和其他用户。速率控制是网络中的一个持续挑战，因为它必须处理各种动态环境，同时在有限的信息下做出毫秒级的决策。该项目旨在基于机器学习领域的强化学习开发新的码率控制方法，从而在性能和功能方面实现潜在的改进。在高层次上，该项目旨在对强化学习在码率控制中的应用有一个基本的理解，并将该理解应用于现代网络视频中常用的自适应比特率（ABR）视频领域，以及传输层拥塞控制，例如传输控制协议（TCP）。这项工作将开始与算法的基础，探索什么水平的复杂性学习算法（从强盗算法到深度神经网络）是必要的，以实现高性能。接下来，该项目将扩展速率控制的输入和输出的语义，包括清道夫速率控制协议和改进的多路径TCP。最后，该项目将使用新的自动化方法来提高速率控制协议在意外环境中的鲁棒性。该项目的结果可以为已部署的协议提供显着的性能改进，这是随着现代和新兴应用对网络要求越来越高而日益增长的需求。例如，低延迟通信和高质量实时视频对于交互式会议、增强和虚拟现实、物联网、边缘计算等都很有价值。该项目还计划为代表性不足的群体提供研究机会。该项目的成果，包括论文和开源代码，将在http://pccproject.net和代码库中提供，https://github.com/PCCprojectThis奖项反映了NSF的法定使命，并被认为值得通过使用基金会的知识价值和更广泛的影响审查标准进行评估来支持。
