Bob/all,

We have published a draft that outlines in great details the architectural framework (based on IP and existing IETF technologies) in the slides presented at lunch speaker session on 5G at the Singapore IETF - draft-bookham-rtgwg-nfix-arch.
There’s already a number of successful deployments.

Cheers,
Jeff

Somewhat more recently Ethernet vs. Token ring. Basically, can networking architectures provide deterministic service (like circuit switching), or is the Internet best effort OK.

Lots of words like "Guarantee transport SLAs for each service”, “Optimize network resources as load conditions change”, etc. I think arguments proposing a new non-ip networking architecture is back to wanting a more deterministic networking (aka circuit switching). I suppose it also has something to do with wanting to sell services to very large numbers of devices (vs. the current Internet model a subscription per enterprise or home user).
