To take advantage of the widespread use of Ethernet in datacenters, RoCE [5, 9] was introduced to enable the use of RDMA over Ethernet.1 RoCE adopted the same Infiniband transport design (including go-back-N loss recovery), and the network was made lossless using PFC.

WebSep 21, 2024 · Enabling IGMP snooping on a layer 2 switch in a LAN segment in which no layer 3 switch exists can result in intermittent multicast connectivity and severe packet loss. Multicasting with Layer 3 switches is much more efficient than with Layer 2 switches because it identifies the multicast packet and sends it only to the intended receivers. WebRDMA can signiﬁcantly improve the robustness under failures (2x∼4x higher throughput under 0.5%∼10% link loss ratio) and improve the overall network utiliza-tion by up to 47%. …
