RDMA Technology for High-Speed Cameras Provides Optimal Image Transfer Over 10GigE

Jul 19, 2023 The landscape of high-speed data transmission is in a constant state of evolution, as new technologies emerge to meet the ever-growing demands of bandwidth-intensive applications. Ethernet User Datagram Protocol (UDP) has been the preferred protocol for streaming data from GigE Vision cameras for many years due to its simplicity and low latency. However, as the demand for higher bandwidth applications beyond 1 GigE continues to rise, a more efficient and reliable transmission standard is necessary to handle the massive increase in data.

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. Teissie 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.
