Learn about feature arc abstraction in DPDK's rte_graph framework in this 32-minute technical talk by Nitin Saxena from Marvell Technology. Discover how this abstraction solves two key challenges: enabling new protocol support as DPDK in-built nodes on a per-interface basis (like IPsec), and providing mechanisms for applications to reuse DPDK in-built nodes without code duplication. The presentation explains how feature arc creates hook points in certain in-built nodes where applications can eject packets at specific networking layers and reinject them at different layers after processing. Explore the design decisions, usability considerations, and practical applications of feature arc within the rte_graph architecture.
