WebJul 29, 2024 · Remote Direct Memory Access (RDMA), which can be deployed in RDMA over commodity Ethernet (RoCEv2) protocol, has the potential to satisfy the requirements. … WebJul 30, 2024 · Remote direct memory access (RDMA) has become one of the state-of-the-art high-performance network technologies in datacenters. The reliable transport of RDMA is designed based on a lossless underlying network and cannot endure a high packet loss rate. However, except for switch buffer overflow, there is another kind of packet loss in the …
WebRDMA packet can be transformed into an Ethernet/IP/User Datagram Protocol (UDP) packet. The UDP header is used for Equal-Cost Multi-Path (ECMP) routing. The destination UDP … WebWhen sending multicast traffic, if the network frequently reconfigures, chances are that some device in the network doesn't support large frames. Choose hardware carefully if intending to use large frame support. The default is 1500. threads This directive controls how many threads are used to encrypt and send multicast messages.
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%. …
