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.

LUCID Vision Labs Inc. - Designs and manufactures innovative machine vision cameras and components. Compact, high-performance GigE Vision cameras are suited for a wide range of industries and applications such as factory automation, medical, life sciences, and logistics.
