indeed - the scale and resilience requirements for such a crucial dimension of the
service argue strngly against semi-centralised solutions - i know of one massive data center
failure which was down to the SDN controller&vlan management, and that was a much simpler (and
localized) problem, which still needed very complex manual access to get the system up again.
the idea that we'd predicate a core critical infrastructure like 5G on the same design mistake
is daft. - I suppose we could replicate the SDN controllers to every cell tower and then run
some state machine replica management algorithm, but why not just run some decentralised
dice&slice scheme in the first place...? what it would look like is actually an interesting
problem - another bad idea (I've seen in the IETF) is something based on BGP:)
