[AusNOG] NBN Co Layer 2 vs. Layer 3 Services

[Skeeve Stevens]

Hey all,

Just a quick question.

At the moment there is a lot of talk of NBN and whether they are going to deliver Layer 2 or Layer 3 services.

I am a little confused about what is meant by that.  In that as ISP's, I would assume that we would only want Layer 2 services from them? Just in kind of a DSL Wholesale/Ethernet wholesale/etc situation that we already have.

Most of our ISP customers would be happy if the NBN operated just like the current wholesale models out there at the moment.  Little ISP calls his aggregator and says he wants a NBN VLAN to this address which they get from NBNCo (if directly if you are big enough and can afford to interconnect yourself), which is turned on and presented at an aggregation port... very much like taking wholesale ethernet from Pipe, Nextgen, Telstra and others today.

This makes sense to me.

But there is a bunch of voices saying they want the NBN Co to do Layer 3... and I am not quite sure what is meant by that?  Users buy bandwidth off the NBN Co? Turning them into a retail ISP?

If this seems like a stupid question, I am sorry about that... but there are some voices who have access to presenting their views and are doing so about NBN should be doing Layer 3... and I am trying to find some understanding about what is actually being suggested.
