Combining rtt and ecn for rocev2 protocol
WebThe proposed RoCEv2 packets use a well-known UDP destination port value that unequivocally distinguishes the datagram. Similar to other protocols that use UDP encapsulation, the UDP source port field is used to carry an opaque flow-identifier that allows network devices to implement packet forwarding optimizations (e.g. ECMP) while …

WebAug 17, 2015 · On IP-routed datacenter networks, RDMA is deployed using RoCEv2 protocol, which relies on Priority-based Flow Control (PFC) to enable a drop-free network. However, PFC can lead to poor application performance due to problems like head-of-line blocking and unfairness. WebMar 8, 2024 · Because RoCEv1 is a multicast protocol on a single ethernet domain, traffic only flows through L2 hardware asics, as opposed to RoCEv2 which can traverse a router and communicate with a host on an entirely separate switch/vlan in another part of the datacenter, not to mention firewall processing.
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.
