            <title>Why a videocall is pointless and videoconferencing is great</title>
            <description><![CDATA[Lately I have been experimenting with Vidyo (www.vidyo.com), a videoconferencing tool designed for the professional SOHO/SMB/Roadwarrior market. And the tests showed why a 2 person video call is a gimmick, and 3 or more is a major difference.<div><br /></div><div><br /><a href="http://www.dadamotive.com/assets_c/2010/07/vidyo-on-windows-7-1073.html" onclick="window.open('http://www.dadamotive.com/assets_c/2010/07/vidyo-on-windows-7-1073.html','popup','width=1075,height=814,scrollbars=no,resizable=no,toolbar=no,directories=no,location=no,menubar=no,status=no,left=0,top=0'); return false"><img src="http://www.dadamotive.com/assets_c/2010/07/vidyo-on-windows-7-thumb-450x340-1073.jpg" width="450" height="340" alt="vidyo-on-windows-7.jpg" class="mt-image-left" style="float: left; margin: 0 20px 20px 0;" /></a><div><br /><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div>The promise of videoconferencing is that you save a lot of time, money and carbon emissions. Or act as a fallback option, as &nbsp;the recent volcano eruptions in Iceland have showed.</div></div><div>Nevertheless so far my practical experience has been with high-end systems (like the wonderful roomsized conference facilities of Cisco) or <a class="zem_slink" href="http://skype.com" title="Skype" rel="homepage">Skype</a> with video.</div><div><br /></div><div>The highend systems are impressive, but its like going to a jobinterview: not a casual thing, you make an appointment and dress up, prepare yourself.&nbsp;&nbsp;Skype on the other hand is great for the sound quality of the wideband codec (if the connection is OK), but I fail to see the added value of &nbsp;a moving picture of my face : as many others, I am disappointed by how I look when viewed through a webcam.</div><div><br /></div><div>So, is there a market for something in the middle? Even when it lacks (as of now) chatting, recording voice and video?&nbsp;</div><div><br /></div><div>The first impressions were OK but nothing convincing. Ok, the image quality is quite good when you have a good camera and connection, the synchronisation between sound and image is better than Skype. Big deal?&nbsp;</div><div><br /></div><div>When we started to have multiperson conversations the difference became serious and obvious. And its not so much the product as the experience of seeing all the faces simultaneously while having a conversation. It makes a LOT of difference between having a conference call by phone or a multiperson videoconference. But why?</div><div><br /></div><div>The difference acording to psychologists s that when you have a conversation between 2 persons, you always know who is talking and who is responding. A good voice quality is enough to sense the reactions and emotions of the other person.</div><div><br /></div><div>This changes completely when there is a multiperson conversation. We as humans have an uncanny subliminal capability to read instantaneously the emotions in a group from the non-verbal communication as expressed by bodylanguage and facial expressions. So being able to see the reactions of people NOT speaking, and them being able to see your reactions adds a lot to the richness and depth of the conversation. And as I can tell from my experience, it does.</div><div><br /></div><div>Vidyo has a good product, as far as I can see. It works on your laptop, is interoperable with highend systems like Polycom and Tandberg. Tandberg apears to have a similar product and others will follow most likely. Great, competition works.</div><div><br /></div><div>The key take away from these tests is that videocalling is a gimmick which does not really add value. Videoconferencing with multiple persons however has a lot of value.</div><div><br /></div></div><div class="zemanta-pixie" style="margin-top:10px;height:15px"><span class="zem-script more-related pretty-attribution"><script type="text/javascript" src="http://static.zemanta.com/readside/loader.js" defer="defer"></script></span></div>]]></description>

            <title>More is indeed more</title>
            <description><![CDATA[The term "High Definition" &nbsp;for video content or TV-channels is used by marketeers for about anything that is better than the standard analog or digital transmissions (mainly on cable networks). It is claimed that compression technologies have evolved to a point where you only need "X" Mbps for a "High Definition" image. "X" is a number between 3 and 20 Mbps, depending on the source.<div><br /></div><div>It is not easy to test these claims in normal life. Last week I had the opportunity for an impromptu test.</div><div><br /></div><div>In the demonstration room of the new headoffice of Reggefiber one could see content on 3 identical large (40 inch+) LED TV screens.&nbsp;</div><div>The Roland Garros semifinal (tennis) was on 3 channels on the screens next to each other. The first standard SD (digital), the second "HD" Nederland 1 (MPEG-4, 11 Mbps, transcoded by the channel), the third "HD" Eurosport (MPEG-2, 20 Mbps without transcoding).</div><div><br /></div><div>The difference between the SD and both HD channels was obvious. But to my surprise the difference between the 11 Mbps and the 20 Mbps channels was also quite visible. The larger bitrate showed more detail, an easier viewing experience.&nbsp;I have never been so close to a large screen without becoming tired.</div><div>Calling shots in or out was easy, you could almost identify each piece of gravel.</div><div><br /></div><div>Yes, more is indeed more.</div><div><br /></div><div><br /></div><div><br /><div><br /></div></div>]]></description>

            <title>Path dependencies in fibre plant architectures</title>
            <description><![CDATA[The recent <a href="http://www.ofcom.org.uk/research/technology/research/emer_tech/fibre/fibre.pdf">report by Analysys Mason for OFCOM</a>&nbsp;("Fibre capacity limitations in access networks") shows again that there are some important path dependencies in the choice of fibre plant architectures for access networks. The <a href="http://arstechnica.com/tech-policy/news/2010/03/the-internet-of-tomorrow-100gbps-to-your-house-by-2030.ars">main stream press focuses on the speed</a> projections but there is a lot more to enjoy.<div><br /></div><div>In a presentation in November in the UK ("Fibre to Britain") I have showed these slides to demonstrate the choices.</div><div><br /></div><div><a href="http://www.dadamotive.com/assets_c/2010/03/pathdependencies1-1022.html" onclick="window.open('http://www.dadamotive.com/assets_c/2010/03/pathdependencies1-1022.html','popup','width=1280,height=800,scrollbars=no,resizable=no,toolbar=no,directories=no,location=no,menubar=no,status=no,left=0,top=0'); return false"><img src="http://www.dadamotive.com/assets_c/2010/03/pathdependencies1-thumb-450x281-1022.gif" width="450" height="281" alt="pathdependencies1.GIF" class="mt-image-left" style="float: left; margin: 0 20px 20px 0;" /></a></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><a href="http://www.dadamotive.com/assets_c/2010/03/pathdependencies3-1028.html" onclick="window.open('http://www.dadamotive.com/assets_c/2010/03/pathdependencies3-1028.html','popup','width=1280,height=800,scrollbars=no,resizable=no,toolbar=no,directories=no,location=no,menubar=no,status=no,left=0,top=0'); return false"><img src="http://www.dadamotive.com/assets_c/2010/03/pathdependencies3-thumb-450x281-1028.gif" width="450" height="281" alt="pathdependencies3.gif" class="mt-image-left" style="float: left; margin: 0 20px 20px 0;" /></a></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div>Unfortunately Analysys Mason limits their view (as seen so often) to IP traffic : the myopic view of pure Internet afficionados forgetting there is more than data packets, like linear RF. They also miss the opportunity of <a href="http://www.dadamotive.com/2009/11/lambda-to-the-home-and-path-dependencies.html">"Lambda to the Home".</a></div><div>Nevertheless they make the same point: architecture choices create path dependencies.</div><div><br /></div><blockquote class="webkit-indent-blockquote" style="margin: 0 0 0 40px; border: none; padding: 0px;"><div><div><i>Each FTTH technology has an upgrade path to support higher capacity for the next five years. However, the fact that TDM GPON solutions require customer premises equipment to operate at a much higher bandwidth than that required for each individual customer, may limit how far it can be upgraded in the medium to long term, especially as the customer premises environment can be challenging. For example the temperature at the customer premises can fluctuate, whereas premises designed to host long-haul network equipment are air conditioned, thereby minimising temperature fluctuation.</i></div><div><i><br /></i></div></div></blockquote><blockquote class="webkit-indent-blockquote" style="margin: 0 0 0 40px; border: none; padding: 0px;"><i>The first observation is that more evolution of enabling technologies is required for PON generations than for PTP architecture, which in a way, makes PTP a less risky technology to invest in. In addition, due to the greater bandwidth scalability of PTP systems, the expected life cycle of each generation of PTP is likely to be longer than that associated with TDM PON. This is an important result, as it indicates that operators will have a longer time to get return on their investment with a PTP architecture compared to a TDM PON architecture, despite a slightly more expensive initial deployment costs (PTP are currently 19% more expensive to deploy than TDM PON systems, mainly due to the additional fibre, and therefore duct infrastructure required).</i></blockquote><blockquote class="webkit-indent-blockquote" style="margin: 0 0 0 40px; border: none; padding: 0px;"></blockquote><i><div><i><br /></i></div><span class="Apple-style-span" style="font-style: normal;">I would add: the one architecture and approach that gives you the highest penetration over the lifespan is by far the most interesting one. Unbundling and flexibility of technology increases penetration so it is a factor you should be more interested in than bandwidth scalability.</span></i><div><i><span class="Apple-style-span" style="font-style: normal;"><br /></span></i></div><blockquote class="webkit-indent-blockquote" style="margin: 0 0 0 40px; border: none; padding: 0px;"><div><i><span class="Apple-style-span" style="font-style: normal;"><i>So from this analysis, we do not believe that there will be any significant barriers in the evolution of FTTH systems capacity. However, we believe the bottlenecks maybe in the upgrade of one generation of FTTH systems to the next, especially if an operator decide to depart from a TDM PON infrastructure to a WDM PON infrastructure. In the UK for example, if, in the medium term, Openreach was to upgrade its GPON network to a WDM PON network, it would need to prepare for it today by allowing for extra space in the splitter site to be accommodate extra equipment (wavelength demultiplexers for WDM PON).</i></span></i></div></blockquote><div><blockquote class="webkit-indent-blockquote" style="margin: 0 0 0 40px; border: none; padding: 0px;"><div><div><i><br /></i></div></div></blockquote><i><span class="Apple-style-span" style="font-style: normal;">Indeed.&nbsp;</span></i></div><div><i><span class="Apple-style-span" style="font-style: normal;">Not a bad report, just missed some obvious points.<br /></span></i><div><br /></div><div><br /></div></div>

            <title>Symmetry:  on averages and variation</title>
            <description><![CDATA[<div><p class="MsoNormal"><span lang="EN-US" style="mso-ansi-language:EN-US"><a href="http://www.iijlab.net/~kjc/">Dr. Kenjiro
Cho</a><span style="mso-spacerun:yes">&nbsp;&nbsp;i</span></span><span lang="EN-US" style="mso-ansi-language:
EN-US">s a renowned researcher of the
Internet in Japan. His famous paper on <i>The Impact and Implications of the
Growth in Residential User-to-User Traffic </i><span style="mso-bidi-font-style:
italic"><span style="mso-spacerun:yes">&nbsp;</span>was the first to point to the
real observed usage of high speed broadband by a large population. <o:p></o:p></span></span></p>

<p class="MsoNormal"><span lang="EN-US" style="mso-ansi-language:EN-US;mso-bidi-font-style:
italic">In my words: at one point in time 5% of the population is a heavy user,
but its never the same 5 %. People use the capacity casual when needed and
expect an immediate response. Just like we use our electricity network, water
network, sewer network. They are not built for averages. <o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="mso-ansi-language:EN-US;mso-bidi-font-style:
italic">Think of sewers pipes from your home, what a mess would it be if they
were designed for the average flow and you try to flush your toilet.</span></p><p class="MsoNormal"><span lang="EN-US" style="mso-ansi-language:EN-US;mso-bidi-font-style:
italic">At the I<a href="http://www.isoc.org/isoc/conferences/bwpanel/">ETF meeting in
Japan last November</a><span style="mso-spacerun:yes">&nbsp;&nbsp;o</span>n "Internet Bandwidth Growth: Dealing
with Reality"<span style="mso-spacerun:yes">&nbsp; </span>Dr. Kenjiro Cho<span style="mso-spacerun:yes">&nbsp; </span>talked about his latest findings (<o:p><a href="http://www.dadamotive.com/Transscipt%20session%20IETF76%20Dealing%20with%20bandwidth%20growth%20Cho.pdf">Transcript session IETF76 Dealing with bandwidth growth Cho.pdf</a>)</o:p></span></p></div><div><o:p></o:p><br /><p class="MsoNormal"><span lang="EN-US" style="mso-ansi-language:EN-US">He used
some statistical terminology in his talk that needs some explanation, lest people
draw the wrong conclusion. Dr. Cho was kind enough to clarify </span><span lang="EN-US" style="mso-ansi-language:EN-US">the data for me, which
I would like to share. </span><span lang="EN-US"><i>[Update]</i></span><span lang="EN-US" style="mso-ansi-language:EN-US"> The interpretation is mine.</span></p><p class="MsoNormal"><span lang="EN-US" style="mso-ansi-language:EN-US">The first
data point is the gradual shift in average residential data consumption in
Japan.</span></p>

<p class="MsoNormal"><span lang="EN-US" style="mso-ansi-language:EN-US"><span style="mso-spacerun:yes">&nbsp;</span>In the period 2005 -2009 the average upload
grew by </span><span lang="EN-US"><b>29 %</b></span><span lang="EN-US" style="mso-ansi-language:EN-US">, the average download however grew by<span style="mso-spacerun:yes">&nbsp;</span><b>117 %</b>. The symmetry ratio's (up:down) changed from </span><span lang="EN-US"><b>1:1</b></span><span lang="EN-US" style="mso-ansi-language:EN-US"> in 2005 and </span><span lang="EN-US"><b>1:1,7</b></span><span lang="EN-US" style="mso-ansi-language:EN-US">
in 2009. The main reason is the increase in streamed video.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="mso-ansi-language:EN-US">But
averages can be misleading (as in the case of your sewer pipe when you flush the
toilet a couple of times per day). An indicator of the variation is the
difference between the </span><span lang="EN-US"><b>mean</b></span><span lang="EN-US" style="mso-ansi-language:EN-US"> (average) value measured and the </span><span lang="EN-US"><b>mode</b></span><span lang="EN-US" style="mso-ansi-language:EN-US"> value of the measured
distribution. (The </span><span lang="EN-US"><b>mode</b></span><span lang="EN-US" style="mso-ansi-language:EN-US"> value is the value that has the highest<span style="mso-spacerun:yes">&nbsp; </span>count in the table of measurements. For
instance the row (400,1,1,1,300,1,2,1,350) has a </span><span lang="EN-US"><b>mean</b></span><span lang="EN-US" style="mso-ansi-language:EN-US"> value of </span><span lang="EN-US"><b>117</b></span><span lang="EN-US" style="mso-ansi-language:EN-US"> and a </span><span lang="EN-US"><b>mode</b></span><span lang="EN-US" style="mso-ansi-language:EN-US">
value of </span><span lang="EN-US"><b>1</b></span><span lang="EN-US" style="mso-ansi-language:EN-US">).<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="mso-ansi-language:EN-US">The bigger
the difference between </span><span lang="EN-US"><b>mode</b></span><span lang="EN-US" style="mso-ansi-language:EN-US"> and </span><span lang="EN-US"><b>mean</b></span><span lang="EN-US" style="mso-ansi-language:EN-US">, the more variation there is in the measured values. <o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="mso-ansi-language:EN-US">The ratio
of observed </span><span lang="EN-US"><b>mean</b></span><span lang="EN-US" style="mso-ansi-language:EN-US"> versus </span><span lang="EN-US"><b>mode</b></span><span lang="EN-US" style="mso-ansi-language:EN-US"> values are<span style="mso-spacerun:yes">&nbsp;
</span><b>123:1</b> in 2005 and </span><span lang="EN-US"><b>93:1</b></span><span lang="EN-US" style="mso-ansi-language:EN-US"> in 2009 for the upload, indicating a very high
variability in usage patterns for the upload. Sometimes some people are sending
large amounts of data.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="mso-ansi-language:EN-US">For the download
the ratio is </span><span lang="EN-US"><b>14:1</b></span><span lang="EN-US" style="mso-ansi-language:EN-US"> in 2005 and </span><span lang="EN-US"><b>8,5: 1</b></span><span lang="EN-US" style="mso-ansi-language:EN-US"> in 2009, less<span style="mso-spacerun:yes">&nbsp;</span>variation than observed in the upload <span style="mso-spacerun:yes">&nbsp;</span>and consistent with the observation that a lot
of streamed video is viewed.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="mso-ansi-language:EN-US">Dr. Cho's
observations show that bandwidth usage in ultra high speed broadband networks
is<span style="mso-spacerun:yes">&nbsp; </span>consistent with a casual usage
pattern with very high variations, like we use other utilities. <o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="mso-ansi-language:EN-US">And that
averages can be very misleading.<o:p></o:p></span></p></div>]]></description>

            <title>T.Googlii</title>
            <description><![CDATA[Harold Feld has created a <a href="http://www.wetmachine.com/totsf/item/1867">hilarious but otherwise quite believable analogy</a> of Google with a certain type a bacteria, T.Gondii:<div><br /></div><blockquote class="webkit-indent-blockquote" style="margin: 0 0 0 40px; border: none; padding: 0px;"><div><div><i>For those unfamiliar with T. Gondii, it goes through two stages. In 
stage one, it can exist in any mammal. But for reproduction, it needs to
 be inside a cat. So T. Gondii alters the behavior of mice. Mice 
infected with T. Gondii have their brain receptors flipped so that they 
find the smell of cat urine attractive. When they find a cat, they 
respond with aggressiveness instead of hiding, rushing out to fight the 
cat. The cat, of course, is very happy to devour the mouse. It does not 
even notice the protozoa cavorting inside it. If it did, it would 
probably say "as long as it keeps bringing me mice, why should I care 
that it's using me to reproduce."</i></div><div><i><br /></i></div><div><i>T. Googlii is quite similar. It needs to get to us to "reproduce" (make 
money). To do this, it must alter the behavior of the platform providers
 so that we consumer kitties can provide T. Googlii with what it needs 
to reproduce. And while this no doubt appears parasitic from the 
mouse/carrier point of view, it looks much more like <a href="http://en.wikipedia.org/wiki/Commensalism">commensalism</a> from 
the perspective of the consumer/cat.</i></div><div><i><br /></i></div><div><i><br /></i></div></div></blockquote>A great explanation of behaviour.]]></description>
