Hi Florian,

Shortly: yes.  

Somewhat longer: DetNet allows to use any "L2 over IP" tunneling method, including but not limited to VxLAN.
RFCs You might be interested regarding interconnecting TSN domains via DetNet:
- RFC9024: Deterministic Networking (DetNet) Data Plane: IEEE 802.1 Time-Sensitive Networking over MPLS 
- RFC8939: Deterministic Networking (DetNet) Data Plane: IP
+1 if You need "service protection" and having an IP-only network: draft-ietf-detnet-mpls-over-ip-preof-04
(Deterministic Networking (DetNet): DetNet PREOF via MPLS over UDP/IP)

Cheers
Bala'zs

Subject: [Detnet] VXLAN for DetNet

Hi WG,
has anyone already considered VXLAN (RFC 7348) in the DetNet context?
It MIGHT be a feasible option to transparently connect two TSNs together via a DetNet.
Do you have any thoughts on that topic if that would be a feasible approach or if there are better alternatives?

Greetings,
Florian
