In this paper we propose SCDP, a general-purpose data transport protocol fordata centres that, in contrast to all other protocols proposed to date,supports efficient one-to-many and many-to-one communication, which isextremely common in modern data centres. SCDP does so without compromising onefficiency for short and long unicast flows. SCDP achieves this by integratingRaptorQ codes with receiver-driven data transport, packet trimming andMulti-Level Feedback Queuing (MLFQ); (1) RaptorQ codes enable efficientone-to-many and many-to-one data transport; (2) on top of RaptorQ codes,receiver-driven flow control, in combination with in-network packet trimming,enable efficient usage of network resources as well as multi-path transport andpacket spraying for all transport modes. Incast and Outcast are eliminated; (3)the systematic nature of RaptorQ codes, in combination with MLFQ, enable fast,decoding-free completion of short flows. We extensively evaluate SCDP in a widerange of simulated scenarios with realistic data centre workloads. Forone-to-many and many-to-one transport sessions, SCDP performs significantlybetter compared to NDP and PIAS. For short and long unicast flows, SCDPperforms equally well or better compared to NDP and PIAS.
