<p class="MsoNormal">Hey All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m curious on feedback from the industry on how everyone would expect a carrier to calculate 95<sup>th</sup> usage over a multiple link transit product.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Client takes 2 or more Transit Ports with a provider for redundancy reasons or for whatever reason they want – ie split backbone.<o:p></o:p></p>
<p class="MsoNormal">Ie ports at 2 or more different locations for whatever reason.<o:p></o:p></p>
<p class="MsoNormal">They would like to buy 95<sup>th</sup> percentile transit – bundled over multiple ports.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">For this scenario - Let’s say they want to commit to 500Mb/sec of transit split over 2x 1Gig ports and pay an excess for anything over 500Mb/sec<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Would you assume the provider :<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">A: <o:p></o:p></p>
<p class="MsoNormal">Aggregates the 2x Links usage figures for the month and then perform 95<sup>th</sup> on the totals
<o:p></o:p></p>
<p class="MsoNormal">Ie Link A + Link B Then do 95<sup>th</sup> calculation. (Do this on Upload and download separately)<o:p></o:p></p>
<p class="MsoNormal">Pick the highest of the upload or the download as the top figure. Bill excess if over 500<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Or <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">B: <o:p></o:p></p>
<p class="MsoNormal">Calculate 95<sup>th</sup> on each link and add the 95<sup>th</sup> of each link together to get the total 95<sup>th</sup>.<o:p></o:p></p>
<p class="MsoNormal">Ie 95<sup>th</sup> of Link A + 95<sup>th</sup> of Link B = Total (Do this on Upload and download separately)<o:p></o:p></p>
<p class="MsoNormal">Pick the highest of the upload or the download as the top figure. Bill excess if over 500<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">One last question – can anyone think of any way to actually abuse option A…
