Para redes de datacenters recentes, o RDMA (Acesso Remoto Direto à Memória) pode aliviar a sobrecarga do conjunto de protocolos TCP/IP. O padrão RoCEv2 (RDMA over Converged Ethernet versão 2) permite RDMA em tecnologia Ethernet amplamente implantada. RoCEv2 aproveita o controle de fluxo baseado em prioridade (PFC) para realizar o ambiente sem perdas exigido pelo RDMA. No entanto, o PFC é conhecido por ter a fraqueza técnica do bloqueio direto. O controle de congestionamento para RDMA é um tópico de pesquisa muito importante para redes de datacenters. Neste artigo, propomos um novo algoritmo de controle de congestionamento para RoCEv2, TIDD (aumento baseado em temporizador e redução baseada em atraso). O TIDD basicamente combina o aumento baseado em temporizador de DCQCN e a diminuição baseada em atraso de TIMELY. Resultados extensivos de simulação mostram que o TIDD satisfaz o alto rendimento e a baixa latência necessários para redes de datacenters.

Abstract: For recent datacenter networks, RDMA (Remote Direct Memory Access) can ease the overhead of the TCP/IP protocol suite. The RoCEv2 (RDMA over Converged Ethernet version 2) standard enables RDMA on widely deployed Ethernet technology. RoCEv2 leverages priority-based flow control (PFC) for realizing the lossless environment required by RDMA. However, PFC is well-known to have the technical weakness of head-of-line blocking. Congestion control for RDMA is a very hot research topic for datacenter networks. In this paper, we propose a novel congestion control algorithm for RoCEv2, TIDD (Timer-based Increase and Delay-based Decrease). TIDD basically combines the timer-based increase of DCQCN and delay-based decrease of TIMELY. Extensive simulation results show that TIDD satisfies the high throughput and low latency required for datacenter networks.
