There would be VPN doing probably ultra low jitter packet isolation in the CRAN fabric and then pretty much any packet VPN technology doing isolation in the DC fabric. However there are also mechanisms to control antennas, control antenna lenses, pick/start/stop/program the digital signal processing software (Numerology) etc. So a VPN can have some of the required properties but no way does it cover everything, and that everything is what is being called a slice.
