Year 2 Report on Requirements, Architecture and Performance Evaluation (D1.4-SP1)

This document summarizes the activities carried out during the second year of the project related to WP1, devoted to providing updated specifications and preliminary performance evaluations of the TIMING components.

Section 2 contains an overview of typical deployment scenarios, including the expected number of devices and data rates, and a summary of the mix of traffic types that a TSN-based industrial communication network could face, along with the service requirements of the different traffic types.

The rest of the sections focus on the different TIMING components:

• The Wi-Fi TSN nodes that provide a wireless extension to the wired TSN data plane of the TIMING architecture.

• The Ethernet TSN nodes that provide the main operational settings to Safran's Ethernet- based segment of the TIMING TSN network and gather the telemetry and system status indicators.

• The TSN controller that includes specialized interfaces to the TSN nodes and the TSN connectivity manager, and is crucial to enable the connectivity manager's provisioning decisions.

• The TSN Connectivity manager (CM) that is a pivotal component in the TIMING architecture, as it is positioned at the apex and interfaces with both TSN and Metro SDN Controllers and the Digital Twin.

• The wireless scheduler that allocates Wi-Fi resources for multiple concurrent services (TSN and BE) in downlink and uplink.

• The Digital Twin (DT) that, in the event of provisioning requests, provides KPI estimations to guarantee that TS flows meet the required performance upon acceptance of these requests.

  This deliverable contains updated requirements and specifications for each component. Additionally, the deliverable describes performance tests and includes preliminary results corresponding to these tests.
