Learn about MTP, the first transport protocol specifically designed to support in-network computing (INC) applications in this conference presentation from NSDI '25. Discover how traditional transport protocols fail to address the unique challenges of application-specific offloads that can mutate, intercept, reorder, and delay messages spanning multiple packets while working within the buffering and computation constraints of network devices. Explore MTP's two core innovations: a novel message-oriented reliability protocol and a resource-specific congestion control framework that natively accommodate the requirements of in-network computing workloads. Examine the researchers' comprehensive evaluation methodology including a full DPDK-based prototype implementation, real-world INC application testing, detailed microbenchmarks, and large-scale simulations that demonstrate MTP's effectiveness in accelerating applications through network device computation offloading.
