网络化的信息物理系统由控制回路驱动，控制回路通常依赖于严格的通信时序保证，需要复杂且不灵活的调度机制来提供必要的确定性。我们以前提出了合作拥塞控制（CoCC）的基本思想，它使弹性控制应用程序共享一个共同的网络合作。通过平衡控制应用程序的资源需求，它实现了公平性w.r.t.控制的质量，并有效地避免拥塞，从而避免有害的延迟和损失，而不需要复杂的调度机制。我们提出了轻量级和有效的解决方案，使CoCC能够处理多个瓶颈，并使其收敛速度提高一倍。我们的评估结果表明，高利用率，低延迟，公平性和快速收敛，可以实现CoCC即使在复杂的多瓶颈的情况下，大量的流。
Networked cyber-physical systems are driven by control loops that commonly depend on tight communication timing guarantees, requiring both complex and inflexible scheduling mechanisms to provide the necessary amount of determinism. We previously presented the fundamental idea of Cooperative Congestion Control (CoCC), which enables elastic control applications to share a common network cooperatively. By balancing the resource demands of control applications, it achieves fairness w.r.t. to the quality of control and efficiently avoids congestion and thus harmful delays and losses without the need for complex scheduling mechanisms. We propose lightweight and effective solutions that enable CoCC to deal with multiple bottlenecks and double its convergence speed. Our evaluation results show that high utilization, low delay, fairness, and fast convergence can be achieved by CoCC even in complex multi-bottleneck scenarios with a high number of flows.
