WebOct 23, 2024 · Unlike InfiniBand hardware multicast, the loss ratio of RDMA multicast over ODBSS is very low. In our test-bed demonstration, we have pushed the loss ratio to be as low as one in 68 billion packets. With ODBSS, if we stay within one dimension, the multicast … WebAug 2, 2024 · RDMA over Converged Ethernet (RoCE) is a network protocol that uses RDMA to provide faster data transfer for network-intensive applications.
