Low-Latency, Deterministic Networking with Standard Linux using XDP Sockets - Magnus Karlsson & Björn Töpel, Intel Corporation
Application areas such as time sensitive networking and packet processing usually require some combination of high throughput, low latency and determinism in their packet processing characteristics. Satisfying these requirements with standard sockets have been found to be challenging, so application writers have resorted to use bare-metal solutions such as DPDK and vendor specific SDKs. While these solutions often manage to meet the tough performance goals, they break a number of security properties of Linux, poses integration challenges and are a lot harder to use than standard sockets.

In this session, we present XDP sockets (AF_XDP), that was introduced in Linux 4.18. XDP sockets have been designed from ground up to be able to deterministically deliver sub microsecond packet latencies and process many millions of packets a second. We will present how to use XDP sockets from user space, an overview of the kernel and driver implementation, as well as a performance evaluation.

Customize Real-Time Linux for Rocket Flight Control System - George Kang, Advanced Rocket Research Center, Taiwan
The flight control system for HTTP-3A rocket developed by ARRC in Taiwan is based on real-time Linux system, building rocket steering and attitude control under high dynamics environment. The major objective of HTTP-3A is to launch a sounding rocket vertically and send a 10 KG of payload with guidance and attitude control to an apogee exceeding 100 KM, while exercising all kinds of technologies of satellite launch vehicle, except the orbit insertion.

Flight control system is the crucial component of rocket avionics system. To its meet mission critical requirements, the flight control system is built on PREEMPT_RT based Linux along with hardware-assisted hard real time sensing and actuation. At present, sensing referring to sensor acquisition is accomplished by real-time capability of actuation, guaranteed by EtherCAT and PREEMPT_RT.
