<p class="MsoNormal"><span style="color:#1F497D">As a kind of side note to this, I’ve heard that the traffic shaping method by NBN Co is less than ideal (I recall something about dropping packets instead of queuing but can’t remember details), and that ISPs
should put traffic shaping rules on their own equipment to avoid performance issues on the links. I did a bit of a Google on the topic but am probably using the wrong terminology to find anything useful. Does anyone have any more information they could share
on this? <o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">Hi Dino, some ISP’s do it different to others, some use PPPOE, some use DHCP, it just depends on what they want to do.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">For an NBN directly connected ISP they take a VLAN from NBN for each CVC on each POI they connect to, then each customer is allocated a VLAN within the CVC VLAN, so you have layer 2 separation between customers,
really whether you use PPPOE or DHCP there is no difference to separation, it’s a matter of choice for ISP’s, unless they use an aggregator which only offers one option like Telstra Wholesale, at present they run their wholesale NBN network over the top of
their retail NBN network, they only offer DHCP.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Regarding the auth, there is no auth when using DHCP necessariy, but you can use radius and DHCP to do it if you want, then just do the accounting based on the IP they are allocated, you can also allocate IP
based on the CVC ID which is presented by NBN, you can set that up as a radius check attribute so that you can control various aspects of the session at connection time.<o:p></o:p></span></p>

<p class="MsoNormal">Hi guys,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Quick question about the NBN deployment. I am looking for a technical answer here. Some NBN services give you a public IP via DHCP and they push a default route with it. How are the customers separated and how is the same IP leased to the
same NBN endpoint every time? Is this something that is different from ISP to ISP or? There is no auth on the endpoint, and it can’t be the MAC either.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m surprised how little people/engineers really know about the fine works of NBN deployment. ( especially the ISP engineers )<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
