FlexTOE - Flexible TCP Offload with Fine-Grained Parallelism

Explore a conference talk on FlexTOE, a flexible TCP offload engine for SmartNICs that eliminates host data-path TCP processing while remaining fully customizable. Learn about its focus on data-path offload of established connections, fine-grained parallelization techniques, and modular design for high performance on wimpy SmartNIC architectures. Discover how FlexTOE compares to host TCP stacks and other TOEs, offering improved scalability for Memcached, reduced host CPU usage, and lower latency for RPCs. Understand its support for C and XDP programs written in eBPF, enabling implementation of popular data center transport features. Gain insights into the challenges of TCP offload to SmartNICs, the FlexTOE offload architecture, and the benefits of parallel TCP processing across different hardware platforms.
