I fully agree with Lou.

DetNet is NOT limited to small networks.
As I wrote before, the key point is that DetNet is not for the big I Internet. One reason is not to try to boil the ocean.
Note that a key motivation for establishing DetNet was to be able to go larger scale than TSN.

Regards,
Janos

The key statement below is "networks that are under a single administrative control or within a closed group of administrative control"  -- this statement allows for any sized network and does NOT restrict DetNets to " small networks ".

I suspect the types of networks you mention below will generally be built "under a single administrative control or within a closed group of administrative control".

Dear Chairs and WG,



I noticed that in DetNet Charter, it mentions that the networks which WG foucs on as following shown.

"The Working Group will initially focus on solutions for networks that are under a single administrative control or within a closed group of administrative control; these include not only campus-wide networks but also can include private WANs. The DetNet WG will not spend energy on solutions for large groups of domains such as the Internet."

IMO, this description seenms to restrict the WAN application and limit the DetNet to  the small networks.

I am not sure the WAN such as Metropolitan area network and Mobile backhaul network is in the scope of DetNet.

Could you please make some clarification about that? Thanks!



Best Regards,

Quan
