Congestion Management for Multicast on ROCE v2 - Implementing Backpressure Mechanisms

Learn about transitioning infrastructure from Infiniband to Ethernet (ROCE v2) in this technical talk from Christoph Lameter of Deutsche Boerse AG. Explore the challenges and solutions for maintaining RDMA operations and multicast functionality during the migration process. Discover how to implement Infiniband-style "backpressure" mechanisms for multicast sender control on Ethernet networks, with detailed examination of ECN congestion management in ROCE v2 and Cisco Pause Frames. Gain practical insights from real-world experiences with hardware, vendors, and protocols while implementing reliable multicast systems in an Ethernet environment.
