They incur delays, meaning interactive performance of applications may also be suffering. The interactive performance might be tolerable with these delays, but it may not be within the transaction ideal of 100ms.</div><div dir="auto"><br></div><div dir="auto">Regards,</div><div dir="auto">Mark.</div><div dir="auto"><div dir="auto"><br></div><div dir="auto"><br></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On 15 May 2017 09:22, "Tim Jones" <<a href="mailto:tim8021q@gmail.com">tim8021q@gmail.com</a>> wrote:<br type="attribution"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">For the lab testing, NBNCo do request access seekers to set 5 minute DHCP lease time (and 5 minute PPPoE keep-alive timeouts) as part of certification testing. <div><br></div><div>Maybe this temporary lab config has made it to production (intentionally or otherwise).</div><div><br></div><div>Cheers,</div><div>Tim</div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, May 12, 2017 at 2:30 PM, Craig O'Toole <span dir="ltr"><<a href="mailto:cotoole@remex.com.au" target="_blank">cotoole@remex.com.au</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><font size="2" face="sans-serif">Anyone from Optus looking after NBN HFC
on the list?</font>
<br>
<br><font size="2" face="sans-serif">Just been investigating an issue where
one of my clients have an Optus NBN HFC service. Optus is delivering dynamic
IPs with a lease time of 5 mins.... </font>
<br>
<br><font size="2" face="sans-serif">Half life of 2.5 mins getting occasionally
dropped, too short a half life for any re-tries. Several re-numbers a day...
Killing Voice calls, (and Netflix) and making IPSEC VPN almost unusable
with DDNS. </font>
<br>
<br><font size="2" face="sans-serif">Can't be good for anyone, let alone
the DHCP servers load....</font>
<br>
<br><font size="2" face="sans-serif">I am happy to confirm and assist diagnosis,
and if anyone has a contact at Optus in the team looking after this part
of the design please send me a contact so I may assist.</font>
<br>
