Photonics Media Webinar: RDMA for High-Speed Cameras. Optimal Image Transfer Over 10GigE

This webinar explores the origins and mechanics of remote direct memory access (RDMA) as well as the RoCEv2 standard, providing a detailed comparison with traditional protocols such as Transmission Control Protocol (TCP) and UDP. Alexis Teissie from LUCID emphasizes the zero-copy transmission capability that RDMA provides, which enables data transmission to bypass the CPU and OS. Furthermore, the presentation provides a comprehensive overview of how this feature affects 10GigE and 25GigE cameras, including benchmark results, and shares valuable insights into the impact of RDMA technology on the machine vision camera industry.
