Introducing Slate YNS

Slate YNS is an embedded software that interfaces with OPC UA applications to provide automated planning and configuration of TSN networks and devices. Slate YNS does not require any user interface, it simply runs in a network device and facilitates the planning of data streams according to the requirements of OPC UA publishers and subscribers. Configuration of network components is achieved using standard YANG models and NETCONF.

Slate YNS Architecture

Slate YNS plans TSN networks using the Slate CNS planning engine from TTTech Industrial. It establishes system requirements through network discovery and by automatically gathering stream requests from OPC UA publishers and subscribers. Devices are automatically configured, and new publishers and subscribers can be added to the network without requiring any reconfiguration of existing network elements.

Slate YNS Operational Model

Slate YNS includes an OPC UA PubSub server that interfaces with publishers and subscribers. The Slate Node software connects the application on an TSN endpoint to the central Slate YNS software. The library requests the planning of TSN streams according to the application’s demands. It configures the local network device and informs the application about required timing properties. Slate YNS interfaces with TSN switches and switched endpoints via NETCONF to distribute the relevant configuration files throughout the network.

Supported TSN Standards

IEEE 802.1Qcp
YANG Model for Bridging

Enables communication of basic bridging configuration data (FDB, VLAN, TE-MSTI) between bridges in combination with NETCONF

IEEE 802.1Qcw
YANG Model for Qbv, Qbu, Qci

Extends capabilities of 802.1Qcp to communication of scheduling, preemption and policing configuration data (ST GCL, ST SDU) between bridges in combination with NETCONF

IEEE 802.1CBcv
YANG Model for CB (2022)

Extends capabilities of 802.1Qcp to communication of redundancy configuration data (SID, FRER, PSFP) between bridges in combination with NETCONF
