• TLDR：In systems built on Robot Operating System 2 (ROS 2) and using Data Distribution Service (DDS), a single network-impaired or throttled subscriber on a RELIABLE topic can cause backpressure that degrades throughput and latency for all other subscribers, including safety-critical ones sharing the publisher, because the publisher's DDS writer can no longer accept new samples. We present Adaptive Bridge, a proxy-based layer that decouples critical subscribers from degraded or noncritical ones, thereby isolating the critical path through topic splitting and dynamic rate control. The proxy acts as a

• TLDR中文：在基于 Robot Operating System 2 (ROS 2) 并使用 Data Distribution Service (DDS) 的系统中，RELIABLE 主题上单个网络受限或被限流的订阅者可能引发反压，从而降低共享该发布者的所有其他订阅者（包括安全关键型订阅者）的吞吐量和延迟，因为发布者的 DDS writer 不再接受新样本。我们提出 Adaptive Bridge，一个基于代理的层，通过主题分割与动态速率控制将关键订阅者与退化或非关键订阅者解耦，从而隔离关键路径。该代理充当
