In many industrial use cases, for example within the discrete manufacturing context, challenging requirements related to reliability, latency and determinism are put on the communication networks. In the last 70 years we’ve seen an evolution from 4-20mA current loops, over field buses and industrial Ethernet systems towards open ICT standards developed within the IEEE Time-Sensitive Networking group.
Adopting these mechanisms and addressing industrial communication requirements, will be standardized within 3GPP Releases 16 and 17. Following these developments, the Open5GCore is in the process of being extended with related Device-side TSN Translator (DS-TT) and Network-Side TSN Translator (NM-TT) features:
- Time synchronization: via gPTP of a distributed 5G interconnected TSN domain and link layer connectivity discovery and reporting functionality.
- Scheduling: TSN capable UPF (TSN Translator) with Hold and Forward functionality of Ethernet PDUs to enable to enable deterministic, deadline-driven industrial communication that supports multiple TSN vendors.
- Management: TSN AF to abstract the 5GS as a TSN bridge to support configuration of TSN flows via a Central Network Controller (CNC) from multiple vendors.
The toolkit can be extended on demand for different RAN and Industrial Network technologies (e.g., for non-3GPP access, fiber optics, or OpenRAN). For more details on use cases where the Open5GCore is used, please check 5g-playground.org.
