Subject: [Detnet] Question on TSN over IP data plane

Hi DetNet,

Please excuse me to ask this dumb question in the following.
I found there are many compositions of TSN/IP/MPLS in DetNet data plane, but TSN over IP is missing. Could anyone kindly explain the reason, or maybe some history if there was?
The reason why I asked this question originates from a case when TSN LAN networks are considered to be connected by a WAN network. Based on the data planes provided by DetNet, it seems MPLS is the only solution for TSN interconnection. Is it the reason that IP itself couldn't provide the entire DetNet capabilities?
Do I miss anything else?

Thanks in advance.

Regard,
Fan
