An Edge-Queued Datagram Service for All Datacenter Traffic

Explore a 16-minute conference talk from NSDI '22 that introduces EQDS (Edge-Queued Datagram Service), a novel approach to datacenter networking. Learn how EQDS moves queuing from the core network to the sending host, enabling support for multiple protocols and in-network switch enhancements. Discover how this innovative service can improve performance for legacy TCP and RDMA stacks, reduce flow completion times, and enhance NVMeOF throughput. Gain insights into the challenges of modern datacenter networking and how EQDS addresses issues of protocol coexistence and network congestion. Understand the potential impact of EQDS on datacenter traffic management and its role in enabling future transport protocol evolution.
