<p class="MsoNormal">Howdy,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I have a requirements for two pieces of hardware and I am interested
to hear:</p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l1 level1 lfo1"><span style="mso-list:Ignore">a)<span style="font:7.0pt "Times New Roman"">
</span></span>Any thoughts or general opinions on device(s) to meet
the requirements below</p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l1 level1 lfo1"><span style="mso-list:Ignore">b)<span style="font:7.0pt "Times New Roman"">
</span></span>Any interest from anyone in:</p>
<p class="MsoListParagraph" style="margin-left:72.0pt;text-indent:-18.0pt;
mso-list:l1 level2 lfo1"><span style="mso-list:Ignore">a.<span style="font:7.0pt "Times New Roman""> </span></span>Renting
the devices to us for a 1 month period; or</p>
<p class="MsoListParagraph" style="margin-left:72.0pt;text-indent:-18.0pt;
mso-list:l1 level2 lfo1"><span style="mso-list:Ignore">b.<span style="font:7.0pt "Times New Roman""> </span></span>Providing
the devices under a sponsorship arrangement for Microsoft TechEd 2010 at the
Gold Coast Convention and Exhibition Centre</p>
<p class="MsoListParagraph" style="margin-left:72.0pt;text-indent:-18.0pt;
mso-list:l1 level2 lfo1"><span style="mso-list:Ignore">c.<span style="font:7.0pt "Times New Roman""> </span></span>Maybe
also providing associated services if relevant?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">We are not interested in purchasing the hardware as the need
is temporary for the month starting August until end of first week of September.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">We need solutions proposed from people with proven delivery
through running a large temporary network with the characteristics below. We’ve
trialled IPTables under these load characteristics and not had a great deal of
success. We won’t be using RRAS this year due to port exhaustion issues
described in the reference material below. We will not be using ISA or TMG. </p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Requirements:</p>
<p class="MsoNormal"><b>NAT Solution</b></p>
<p class="MsoNormal">We need a NAT solution with the following characteristics:</p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l0 level1 lfo2"><span style="font-family:Symbol"><span style="mso-list:Ignore">·<span style="font:7.0pt "Times New Roman"">
</span></span></span>Must support 3500 concurrent users on the inside
of the NAT.</p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l0 level1 lfo2"><span style="font-family:Symbol"><span style="mso-list:Ignore">·<span style="font:7.0pt "Times New Roman"">
</span></span></span>Must translate ~500mbps of traffic. I don’t
have any guidance on packet size distribution, sorry.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"><b>Traffic Shaping Solution</b></p>
<p class="MsoNormal">In tandem with the above requirement we need:</p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l0 level1 lfo2"><span style="font-family:Symbol"><span style="mso-list:Ignore">·<span style="font:7.0pt "Times New Roman"">
</span></span></span>To discriminate peer to peer traffic going
through the NAT solution above.</p>

</span></span></span>Either block, or shape said traffic.</p>

</span></span></span>We do NOT want a captive portal solution or
anything that requires registration as that will ruin the delegate experience
for phones, games consoles etc that either can’t – or do a bad job
of – browsing the web).</p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l0 level1 lfo2"><span style="font-family:Symbol"><span style="mso-list:Ignore">·<span style="font:7.0pt "Times New Roman"">
</span></span></span>We do NOT want a transproxy. We’re after
something that will shape at the IP level, not HTTP. </p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l0 level1 lfo2"><span style="font-family:Symbol"><span style="mso-list:Ignore">·<span style="font:7.0pt "Times New Roman"">
</span></span></span>Needs to cope with users at wire-speed on the inside
of the device (they will be split between 144mbps wifi and 100mbps Ethernet)</p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l0 level1 lfo2"><span style="font-family:Symbol"><span style="mso-list:Ignore">·<span style="font:7.0pt "Times New Roman"">
</span></span></span>Any other traffic management features your
solution may offer that you might think we would be interested in.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"><b>Background</b></p>
<p class="MsoNormal">In previous years, Microsoft has provided open and
unfettered access to delegates at TechEd. We have deliberately taken the stance
of providing the highest throughput with no shaping so that users can use
whatever bandwidth is available for purposes relevant to the event. </p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">We have run the network this way since 2004 with great
success. Unfortunately, TechEd2009 saw a small number of users take advantage
of this policy. This caused us issues as described here:</p>

<p class="MsoNormal">We are happy to discuss this further on or off list, as
appropriate. </p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Responses via e-mail only though please (my phone seems to
melt after I post something to ausnog that might result in someone selling me
something). I will compile a list of candidate solutions and present them back
to the TechEd technology team/monkeys for their consideration. </p>
