Remote Direct Memory Access (RDMA) with Atlas10 Cameras
This white paper delves into the ways in which RDMA technology is transforming high-speed Ethernet machine vision cameras. It explores the origins and mechanics of RDMA, as well as the RoCEv2 standard, providing a detailed comparison with traditional protocols such as TCP and UDP. The paper emphasizes the zero-copy transmission capability that RDMA provides, which enables data transmission to bypass the CPU and OS. Furthermore, the paper presents a comprehensive overview of how this feature affects 10GigE and 25GigE cameras, including preliminary benchmark results. By reading this white paper, you can gain valuable insights into the impact of RDMA technology on the machine vision camera industry.
