Re: [Detnet] [5gangip] Network Slicing - a suggestion that we meet to discuss in Seoul

This stuff is routine in multi-tennant data centers where you want to
isolate tennants both at the VM level and at the VPN level, so you
need to dice and slice everything from app, os, nic, switches and
links....
lots of hypervisors&NICs support this at scale in that context - it
needs documenting how its managed, the importing into the ietf/5g
world....
