DDS Extensions for Time Sensitive Networking 1.0 — Spec Coverage

Source: docs/standards/cache/omg/dds-tsn-1.0-beta2.pdf (OMG DDS-TSN 1.0, ptc/2024-05-16; not tracked in the repo for IP/copyright reasons). Public spec page: https://www.omg.org/spec/DDS-TSN/.

Repo: crates/transport-tsn/ — PIM configuration model (§7.2) + XML/JSON/YANG PSM (§7.3) + DDSI-RTPS Ethernet PSM (Annex A), pure-Rust no_std+alloc. Live AF_PACKET transport under feature live. 93 lib tests green (default), 105 with --features live (+12 platform-neutral live_frame tests) + veth roundtrip integration test (CI, root).

Context: DDS-TSN brings DDS onto IEEE 802.1 Time-Sensitive Networking. ZeroDDS implements the PIM configuration model (§7.2 wire-relevant tables), all three configuration PSMs (§7.3: XML, JSON and the normative YANG group transformation §7.3.3) and the DDSI-RTPS Ethernet PSM (Annex A) as a pure-Rust no_std+alloc library — including an optional live AF_PACKET transport (feature live, Linux). The TSN-UNI wire protocol (transport of the YANG groups over the concrete UNI protocol) + the 802.1AS PTP daemon + hardware acceleration (TX timestamping via SO_TIMESTAMPING/PHC) are caller-layer.

§3 normative references (IEEE 802.1Qbu frame preemption / 802.1CB FRER): the spec lists these in §3 as external IEEE references; §2 explicitly declares no independent conformance points for them. They are therefore not standalone DDS-TSN mappings — 802.1CB surfaces as num_seamless_trees (NetworkRequirements, Tab 7.18/7.25) and in the YANG interface-capabilities (cb-*-list), 802.1Qbv as TimeAware (Tab 7.17). No open gap.

§7.3 Configuration Representation (PSM)

All three normative PSMs are covered.

§7.3.1 XML PSM

Tests: pim::xml::tests::* (11).

§7.3.2 JSON PSM

Repo: crates/transport-tsn/src/pim/json.rs::render_dds_tsn_json — renderer in the spec JSON schema.

Tests: pim::json::tests::* (4).

Status: done

§7.3.3 YANG PSM

Spec: §7.3.3, p. 23-27 — transformation of the configuration model into the YANG data-module definitions from IEEE 802.1Q §46.3 (Talker/Listener groups for the UNI exchange CUC↔︎CNC). Normative and NOT covered by the JSON PSM — it is a distinct mapping (stream-id-type, group-talker/group-listener with the 802.1Q/802.1CB interface-capabilities).

Repo: crates/transport-tsn/src/pim/yang.rs — the §7.3.3 transformation rules 1:1:

  • StreamId (stream-id-type): 6-octet node MAC + 16-bit DataWriter ID, YANG string AA-BB-CC-DD-EE-FF-NN-NN (IEEE 802.1Qcc).
  • GroupTalker::from_talker: stream-rank=1, end-station-interfaces, optional data-frame-specification (Ethernet MAC+VLAN / IPv4 / IPv6 incl. dscp), traffic-specification (interval as numerator/denominator, max-frames-per-interval, max-frame-size, transmission-selection, time-aware with zero when unspecified), optional user-to-network-requirements, interface-capabilities.
  • GroupListener::from_listener: end-station-interfaces, user-to-network-requirements, interface-capabilities.
  • talker_listener_groups: a whole TsnConfiguration → groups, with sequential DataWriter IDs (§7.3.3.1).
  • RFC 7951 YANG-JSON renderer (to_yang_json).

RFC 7950 YANG source parsing (reading textual .yang modules) is caller-layer; the spec requires producing the YANG group representation, not parsing foreign .yang files.

Tests: pim::yang::tests::* (17, incl. stream-id construction, data-frame branches, interval fraction, time-aware zero rule, UNR present/absent, YANG-JSON well-formedness).

Status: done

Repo: cross-ref crates/rtps/ + crates/discovery/ (see ddsi-rtps-2.5.md).

Tests: cross-ref ddsi-rtps-2.5.md.

§8.4 DDSI-RTPS Ethernet PSM (refers to Annex A)

Repo: crates/transport-tsn/src/ethernet_psm.rs.

Status: done

Annex A — DDSI-RTPS Ethernet PSM

Spec: Annex A, p. 33-36 — RTPS directly in the Ethernet frame payload.

Repo: crates/transport-tsn/src/ethernet_psm.rs::{EthernetFrameHeader, ETHERTYPE_RTPS}. Header with/without VLAN tag (14 vs 18 bytes), round-trip, truncation detection, IPv4-EtherType non-VLAN branch.

Live transport (feature live, Linux): crates/transport-tsn/src/socket.rs::TsnTransport sends/receives RTPS directly in the Ethernet frame over an AF_PACKET/SOCK_RAW socket; the platform-neutral frame logic (VLAN selection, frame build + min-frame padding, sysfs MAC parsing) lives in live_frame.rs.

Tests: ethernet_psm::tests::* (7); live_frame::tests::* (12, platform-neutral); tests/veth_loopback.rs — real RTPS roundtrip over a veth pair (root, CI tsn-live job, see docs/ci/tsn-live.md).

DDS Extensions for Time Sensitive Networking 1.0 — Spec-Coverage

Quelle: docs/standards/cache/omg/dds-tsn-1.0-beta2.pdf (OMG DDS-TSN 1.0, ptc/2024-05-16; aus IP-/Copyright-Gründen nicht im Repo getrackt). Öffentliche Spec-Seite: https://www.omg.org/spec/DDS-TSN/.

Repo: crates/transport-tsn/ — PIM-Configuration-Modell (§7.2) + XML/JSON/YANG-PSM (§7.3) + DDSI-RTPS-Ethernet-PSM (Annex A), pure-Rust no_std+alloc. Live-AF_PACKET-Transport unter Feature live. 93 lib-Tests grün (Default), 105 mit --features live (+12 plattformneutrale live_frame-Tests) + veth-Roundtrip-Integrationstest (CI, root).

Kontext: DDS-TSN bringt DDS auf IEEE-802.1-Time-Sensitive- Networking. ZeroDDS implementiert das PIM-Configuration-Modell (§7.2 wire-relevante Tables), alle drei Configuration-PSM (§7.3: XML, JSON und die normative YANG-Group-Transformation §7.3.3) und das DDSI-RTPS-Ethernet-PSM (Annex A) als pure-Rust no_std+alloc Library — inkl. optionalem Live-AF_PACKET-Transport (Feature live, Linux). TSN-UNI-Wire-Protocol (Transport der YANG-Groups über das konkrete UNI-Protokoll) + 802.1AS-PTP-Daemon + Hardware-Acceleration (TX-Timestamping per SO_TIMESTAMPING/PHC) sind Caller-Layer.

§3 normative Referenzen (IEEE 802.1Qbu Frame-Preemption / 802.1CB FRER): Die Spec listet diese in §3 als externe IEEE-Referenzen; §2 deklariert explizit keine eigenen Conformance-Points dafür. Sie sind also keine eigenständigen DDS-TSN-Mappings — 802.1CB taucht als num_seamless_trees (NetworkRequirements, Tab 7.18/7.25) und in den YANG-interface-capabilities (cb-*-list) auf, 802.1Qbv als TimeAware (Tab 7.17). Kein offenes Loch.

Normativ und NICHT durch das JSON-PSM abgedeckt — es ist ein eigenes Mapping (stream-id-type, group-talker/group-listener mit den 802.1Q/802.1CB- interface-capabilities).
