Uno - A One-Stop Solution for Inter- and Intra-Data Center Congestion Control and Reliable Connectivity

Explore a research presentation introducing Uno, a unified system designed to address congestion control and reliable connectivity challenges in both inter- and intra-datacenter environments. Learn about the motivation behind developing this solution, including the complexities that arise when intra- and inter-datacenter traffic coexist within datacenters and the rate unfairness issues caused by disparate round-trip times. Discover the specific challenges facing inter-datacenter communication, such as slow loss recovery and the need for enhanced reliability. Examine UnoCC, the congestion control component that enables rapid congestion reaction and fair rate control across different network environments. Understand UnoRC, the load balancing scheme that combines erasure coding with adaptive routing to optimize traffic distribution. Analyze comprehensive results demonstrating how Uno significantly improves completion times for both inter- and intra-datacenter flows compared to existing state-of-the-art methods like Gemini. Gain insights into this cutting-edge research addressing the unprecedented communication demands driven by cloud computing and AI workloads, presented by researchers from ETH Zurich's Scalable Parallel Computing Lab.
