Peter Fetterolf's paper delivers a comparison between the two leading network technologies, InfiniBand and RDMA over Converged Ethernet (RoCE), outlining the technical and economic advantages of RoCE, particularly in terms of availability, familiarity among engineers, and the faster development trajectory of Ethernet technologies. The paper explores the benefits of automated network operations, which significantly reduce operational expense (through intent-based automation, as exemplified by Juniper Apstra. His analysis shows that deployments of Juniper Ethernet with RoCE and Apstra result in 55% total cost of ownership savings, including 56% operations expense savings and 55% capital expense savings over the first three years versus InfiniBand networks.
