Explore a groundbreaking conference talk on Poseidon, a novel congestion control (CC) protocol that leverages in-network telemetry (INT) to address longstanding challenges in datacenter networks. Learn how Poseidon achieves efficiency through low queuing delay, high throughput, and fast convergence, while decoupling bandwidth fairness from traditional AIMD control laws. Discover the protocol's robustness in handling multi-hop and reverse-path congestion, as well as its practicality for incremental deployment in mixed INT and non-INT switch environments. Gain insights into Poseidon's significant improvements over state-of-the-art CC algorithms, including reduced fabric RTT, faster convergence, and decreased throughput variation. Understand how these advancements translate to substantial end-to-end application performance gains, with potential reductions in message transfer time averaging 61% and up to 14.5× at the 99.9th percentile.
