TSN
- IEEE 1722 Part 1 — Fundamentals: AVTP and IEEE 1722-2025
The opener of the IEEE 1722 series: what AVTP is, which AVTPDU formats exist (AAF, CRF, IIDC, RVF), and how native Ethernet framing differs from optional UDP encapsulation.
- IEEE 1722 Part 2 — ACF (AVTP Control Format): Field-Bus Tunneling over TSN
ACF in the AUTOSAR module IEEE1722Tp: ACF_CAN and ACF_LIN, TSCF vs. NTSCF, bundling multiple field-bus messages, and why it matters for zonal architectures — including a clear boundary against Open1722's broader format scope.
- IEEE 1722 Part 3 — ARXML Configuration of the IEEE1722Tp Module
The real container structure of IEEE1722Tp in the ARXML per Chapter 10 of the SWS: IEEE1722TpStream, PDU pools, stream subtypes — and why stream-to-switch-port mapping runs indirectly through generic PDU routing.
- IEEE 1722 Part 4 — End-to-End Practical Examples with Open1722
Two followable end-to-end examples with Open1722: a camera stream from capture to deterministic delivery, and a CAN subnet transparently tunneled via ACF.CAN over a TSN backbone.
- IEEE 1722 Part 7 — CAN-XL & CAN-XL Brief: the Most Practically Relevant Gap
ACF_CANXL and ACF_CAN_XL_BRIEF in detail: VCID, SDT, acceptance field, and segmentation — the new header fields from IEEE 1722-2025 that AUTOSAR (R24-11) doesn't yet know.
- IEEE 1722 Part 9 — Generic & Abbreviated Byte Bus (GBB/ABB): Tunneling Without a Dedicated Protocol
ACF_GBB and ACF_ABB in detail: the generic request/response format from IEEE 1722-2025 for bus systems without their own ACF format — and why it matters for niche automotive protocols.
- EthSwt — TSN Stream Identification, Filtering & Policing
How EthSwt identifies Ethernet frames as streams using AND-linked filter rules, and which filter actions (drop, block-source, VLAN modification, egress redirection) can follow.
- EthSwt — Time-Aware Shaping & Frame Preemption (TSN)
Cascaded egress schedulers, credit-based shaping and enhanced transmission selection, plus IEEE 802.1Q frame preemption — the core AUTOSAR mechanisms for deterministic Ethernet in the switch.
