Netdev 0x16 - dcPIM Low latency, High throughput, Receiver driven Transport Protocol

Speakers: Qizhe Cai Rachit Agarwal Info: Modern datacenter networks bear a striking similarity to switch fabrics: both of these are organized around Clos-like topologies using low-port count switches and both of these experience similar workloads---incast (many input ports having packets for the same output port), all-to-all (each input port having packets for each output port), one-to-one, etc. Yet, scheduling mechanisms in state-of-the-art datacenter transport designs are significantly different from those used in switch fabrics. Bridging this gap has the potential for datacenter transport designs to benefit from decades of foundational work on switch scheduling that has led to near-optimal switch fabric designs.
