Combining rtt and ecn for rocev2 protocol
WebUse explicit congestion notification (ECN) with RoCEv2 as ECN bits are communicated end-to-end across a routed network. Enable RDMA over Converged Ethernet with PFC RoCEv1 uses the Infiniband (IB) Protocol over converged Ethernet. The IB global route header rides directly on top of the Ethernet header. Web2. Combining RTT and ECN for RoCEv2 protocol has been proposed to generate CNP generation mechanism and rate adjustment strategy of DCQCN. 3. Buffer sizing with HPCC has been used in RDMA, with the same parameter settings as in …
