It's worth noting that Chorus are constrained to Layers 1 and 2 only - no routing!
Which I personally would argue for various reasons is an untenable and ridiculous technical position to force anyone to take.
It sounds ridiculous until you consider how many corner cases it solves.
If Chorus and/or the Local Fibre Companies are allowed to offer routed (L3) traffic, then:
I would have to respectively disagree that there is really any more complication than already exists. Why are you invoking metering and caching or multicast for that matter and differentiated pricing it is still a UFB /MEF network underneath it. I think you are perhaps mistaking advocating for a VPLS at the Aggregation switches rather than E-PIPES (thus allowing switching before the traffic gets to the RSP handover upstream).. I would argue here also there are good arguments to at least allow for a Service Provider to have services bundled into an VPLS so that CPE to CPE traffic on the same SVLAN doesn't soak up backhaul... but I digress. All I was describing was a Layer3 routed WAN service, it would still be marked and routed[sic - switched] as the existing UFB constructs. There just happens to be a LFC run IPAM dishing out addressing at an RSP handover that happens to be an LFC. It solves for the cases that are going to transpire where XYZ organisation wants a WAN service between all it's newly connected UFB premises but doesn't want to have to deal with APNIC/Address allocations etc. I get the argument that that is a Market opportunity for an RSP to manage such a service on behalf... but it just seems like it is going to cause problems artificially limiting LFC from providing **ANY** sort of l3 services. I think regardless of the WAN service scenario described that it would be desirable to have a V6 management/monitoring portal. If you do this you can serve up things like Customer Self provisioning portals - which ultimately means more choice and faster provisioning. It would also make management and performance monitoring easier. Jonathan - there is always l2tpv3 .
