In addition to the network deployed in the data center, there is a parallel network that adheres to TSN (Time-Sensitive Networking) standards. This network is designed to support services requiring low latency and high availability. The network is composed of four TSN switches,  each of them having a PC with one TSN PCIe NIC. Additionally, there is a centralized SDN-based control plane (CUC/CNC)
for the management of the network, following the IEEE 802.1Qcc standard. They are located in the CBL data center, in the DronLab, and a research laboratory. The switches in the DronLab and in the lab are connected to the data center switch, forming a star topology. The links are of 1/10 Gbps speed.

Use Cases

TSN solutions are commonly used in environments where latency is key, for example, industrial networks. In the deployed network, a use case of this network would be:

• 5G-TSN integrated scenarios for Industrial Communication. A 5G-TSN testbed, following the 3GPP standard, has been built with TSN switches, the CUC/CNC centralized control plane, and 5G core network software (Open5GS and UERANSIM), in the context of the 6GSMART project (https://i2cat.net/unico/6gsmart/).
