Skeeve - as far as ISOC-AUs view, refer to the two submissions <a
href="http://www.isoc-au.org.au/Submissions/NBNCo_Feb2010FINAL.pdf">Submission
on the NBN Consultation Paper: Proposed Wholesale Fibre Bitstream
Products</a> and <a
href="http://www.isoc-au.org.au/Submissions/NBN_Senate_March10.pdf">Summary
to the Senate Select Committee: ISOC-AU Submissions on the NBN</a>.<br>
<br>
Both include the statement "ISOC-AU is concerned that by restricting
itself to a Layer 2 focus, the opportunities will be<br>
reduced to adopt optimal approaches to Internet security and ensuring
the broadest<br>
possible access to innovative Internet services. ISOC-AU sees that the
ideal approach is<br>
one where NBN Co provides layer 2, aggregated layer 2 and layer 3
services."<br>
<br>
In these papers, the preference for Layer 3 is expressed as a desire
for NBN to be able to do multicast, which necessarily requires a
Layer-3 appreach to understand IGMP spoofing (v4) and the equivalent in
IPv6. I encourage you to read through both these.<br>
<br>
As far as Tony's statements to the Senate Select Committee - I'll pass
your views along, I've expressed some similar concerns. <br>
In fairness, I know that its very difficult to be clear in these live
hearings, when everything is taken down verbatim - I know when I have
fronted up for these things, I read some of things I actually said and
think "hang on, I didn't quite mean it like that" (and I don't suggest
for a moment that Tony thinks the same way about the things said
recently).<br>
<br>
My personal view (NOT the ISOC-Au view) as expressed in another forum
is:<br>
<br>
<i>The plan for the NBN has always addressed Layer 3 - by explicitly
acknowledging that the NBNCo services should not and would not stand in
the way or inhibit the delivery of Internet or private Layer 3 services
in any way, by limiting itself to providing only lower-layer conduits
to service providers, and staying transparent to layer-3 protocol
exchanges.
<br>
</i><br>
or more succinctly:<br>
<br>
<i>The NBN enables the effective delivery of layer-3 and IPv6 - by
staying out of the way.
<br>
<br>
</i>IAMEMS might be a good place to debate this a bit further amongst
ISOC-AU members.<br>
