Is the following extract from this Heavy Reading white paper
<https://www.infinera.com/wp-content/uploads/HR-Operator-Strategies-for-5G-Transport-July-2020_WP.pdf>,
useful?

" For transport network slicing,
operators strongly prefer soft slicing with virtual private networks
(VPNs),
regardless of the VPN flavor.
Ranking at the top of the list was Layer 3 VPNs (selected by 66% of
respondents),
but Layer 2 VPNs, Ethernet VPNs (EVPNs), and segment routing
also ranked highly at 47%, 46%, and 46%, respectively.
The point is underscored by the low preferences among all of the hard
slicing technologies—
those that physically partition resources among slices.
Hard slicing options formed the bottom tier among preferences."
