BKK19-504 - XDP Offload for OPC UA

Session Abstract

OPC Unified Architecture (OPC UA) is a machine to machine communication protocol for industrial automation. One of the challenging task is to lower network latency for request on measurement node (receive part of the network stack). Because of measurement value carry timestamp there is no strict latency requirement to tx path. This talk is about experimental way to use eXpress Data Path (XDP) sockets merged to the latest mainline kernel with zero copy packets to userspace with LWIP network stack in application instead of linux kernel network stack.
