Re: [Detnet] [DetNet] Discussion on the WAN application in DetNet charter

Hi Lou, Janos and Andy,

Thanks for your clarification! It is very appreciated!

I probably understand the scope of the DetNet.  The networks which are in a single  administrative control are in scope of the DetNet. 

For example, the mobile backhaul network which is in a single administrative control is defintly included in DetNet.

But what about the small networks which belong to different domains and large networks which  belong to a single domain?

IMO,  the description in charter is confuesd.  It only mentions the campus-wide networks and private WANs.

Best Regards,

Quan
