Complementing TCP with Homa - Network Protocol Analysis and FPGA Acceleration

Explore a 46-minute conference presentation from SNIA SDC 2023 that delves into the coexistence and acceleration possibilities of Homa protocol alongside TCP in datacenter networks. Learn how these protocols can complement each other, with TCP handling data streams and Homa managing shorter messages for improved tail-end latencies. Discover the integration of HomaModule, an open-source Linux Kernel implementation, with FPGA NIC Corundum.io for protocol acceleration. Examine experimental results showing 5x improvements in slowdown and RTT when applying CPU offloading concepts like receive side scaling, segmentation, and large receive offloading. Master key concepts including TCP tail latencies, computational burdens, and the advantages of Stanford University's Reliable, Rapid Request-Response Protocol (4RP) in storage networking and GPU cluster applications. Presented by Endric Schubert and Ulrich Langenbach from Missing Link Electronics, this technical deep-dive provides valuable insights into modern datacenter protocol optimization and acceleration techniques.
