<P><FONT SIZE=2>Ah, but she didn't say she believed it. Just said where the data was...</FONT>
</P>
<P><FONT SIZE=2>Do we really need to verify what it shows? At best, it shows that they have spotty reporting. At worst, it shows rather severe reliability problems. Take your pick...</FONT></P>

<BR><FONT SIZE=2>> HHHMMM... Very interesting. Someone who believes what a </FONT>
<BR><FONT SIZE=2>> carrier really </FONT>
<BR><FONT SIZE=2>> tells them.</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> If you go to the MFN homepage & click on the graphs listed </FONT>
<BR><FONT SIZE=2>> below, then you </FONT>
<BR><FONT SIZE=2>> might see that possibly the data being displayed is both </FONT>
<BR><FONT SIZE=2>> inaccurate, as well </FONT>
<BR><FONT SIZE=2>> as misleading.</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> Go to SJC OC3 Los Angeles, to OC192 SJC3 to SJC4, to OC12 </FONT>
<BR><FONT SIZE=2>> MaeW ATM, OC48 # 2 </FONT>
<BR><FONT SIZE=2>> for IAD to NYR, IAD # 2 to PAIX VA OC48, DCA2 to DFW2 OC48, </FONT>
<BR><FONT SIZE=2>> PAIX OC12 to </FONT>
<BR><FONT SIZE=2>> Core1.sjc, NPA - DS3 to San Jose, LGA1 OC192#2 to IAD, LGA1 </FONT>
<BR><FONT SIZE=2>> OC48 to Chicago, </FONT>
<BR><FONT SIZE=2>> NYC Backbone OC192 to LGA2, NYC Backbone OC48 # 2 to </FONT>
<BR><FONT SIZE=2>> core3.lga1, ETC...</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> Each one of these graphs shows abnormalities in the flow of </FONT>
<BR><FONT SIZE=2>> internet data, </FONT>
<BR><FONT SIZE=2>> such as "pits", spikes, square wave function graphs, clipping on some </FONT>
<BR><FONT SIZE=2>> waveforms, etc.</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> This is not limited to MFN. I have observed this on other </FONT>
<BR><FONT SIZE=2>> similiar types of </FONT>
<BR><FONT SIZE=2>> Sundry network data collection systems.</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> It is not easy to see HOW BAD the problem is with these Sundry data </FONT>
<BR><FONT SIZE=2>> collection systems, UNTIL you expand the MRTG graph. Once </FONT>
<BR><FONT SIZE=2>> this is done, </FONT>
<BR><FONT SIZE=2>> then you can really see how bad the integrity of the </FONT>
<BR><FONT SIZE=2>> collected data really </FONT>
<BR><FONT SIZE=2>> is. A small MRTG graph really masks the problems associated </FONT>
<BR><FONT SIZE=2>> with the data </FONT>
<BR><FONT SIZE=2>> which is being displayed. With a larger graph, you </FONT>
<BR><FONT SIZE=2>> definately see the </FONT>
<BR><FONT SIZE=2>> problems associated with todays Sundry systems.</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> As there is no way to really verify the QUALITY or INTEGRITY </FONT>
<BR><FONT SIZE=2>> of the data </FONT>
<BR><FONT SIZE=2>> being displayed, then I submit as fact, that what is being </FONT>
<BR><FONT SIZE=2>> shown here is </FONT>
<BR><FONT SIZE=2>> really in a grey area, at best.</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> So who really knows how correct, the data which is being </FONT>
<BR><FONT SIZE=2>> displayed on the </FONT>
<BR><FONT SIZE=2>> MFN home page is really is ?</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> Cause with the clipping, spiking, pits, & squarewave graphs, </FONT>
<BR><FONT SIZE=2>> small graphing </FONT>
<BR><FONT SIZE=2>> scale being shown, definately, I have my doubts ...</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> One would also wonder, that if this data collection system is </FONT>
<BR><FONT SIZE=2>> used by MFN to </FONT>
<BR><FONT SIZE=2>> generate bills for customers of MFN who are charged by the </FONT>
<BR><FONT SIZE=2>> Megabyte, what </FONT>
<BR><FONT SIZE=2>> these customers bills look like & HOW accurate these bills </FONT>
<BR><FONT SIZE=2>> really are...</FONT>
