<a href="http://x.mepemepe.com/wiki/Digital_School_in_the_Box">http://x.mepemepe.com/wiki/Digital_School_in_the_Box</a> is the project that SJ referenced, and they are indeed going forth with XOs for the first prototype (last I heard - supposedly they will deploy the prototype next week, based on the conversation that I had with the folks there last week). They welcome comments on their wiki talk page.<br>
<br>I bring this up because the UNICEF tech crew working on this has plenty of in-the-field network infrastructure deployment experience in a whole range of remote and difficult secnarios (and probably contact with people who have much more). If there are questions on what use-cases would be good/vital to plan for, or how setup X would actually look to the folks who'll be deploying it in the field, they might be great people to talk to.<br>
<br>It doesn't address how to solve things technically (although they have some pretty talented hackers - who knows, they might have suggestions) but could help in "backing up" the priority list of which problems should be solved most urgently. Not sure if this is helpful right now.<br>
<br>Also, to answer Daf's original question, I took a stab and put up <a href="http://wiki.laptop.org/go/Networking_scenarios">http://wiki.laptop.org/go/Networking_scenarios</a> (with some discussion from this thread on the talk page) - move/edit/delete and all the usual if I've duplicated something. This page is currently an orphan, so if someone could link to it from some other relevant pages, I'd be most grateful.<br>

Javier,<br><br>The humble towns are most important. <br><br>An aside : when I was last in New York (for the story jam a couple weekends ago) I saw a UNICEF poster display of a disaster-area "school in a box" -- two suitcase-sized containers with all of the materials and power-generators needed to run a single server creating its own sat or radio internet connection, and a few attached terminals. The design was for regions with no infrastructure at all. A poster mockup listed XOs as ideal terminals... <br>

<pre>Hello Dafydd and all...
<u><b>Question:</b></u>
I think that you mean that the "school server" has "internet access".
Is it possible to have a "school server" without "internet access" ? (just to do... what? bigger "collaboration" between the XOs? software repository? documents & books repository?. Many scenarios are possible.
So I think you can add to the fourth scenarios: "Internet access" or "No internet access" and what kind: ADSL, phone line, Satelital, or other ways.
<u><b>Idea:
</b></u>Add to your scenarios:
"Kind of energy available for the XOs:"
Then we will face the "forgotten" problem: the humble towns, the ones that are over the
3,500 meters altitude, the ones that are in the "worst" scenarios... they don't have any
kind of electricity. So the "cranck", the "solar panels", air or human generated energy
is part of the equation IF we are going to reach those "worst scenarios".
Helping first the ones that will survive? That is for first aid in disasters. In this
case we must try to help the "forgotten" worst scenarios and I hope that MOST of the
XOs that come to Peru will go to the poorest towns.
<u><b>Comment:</b></u>
You say: <font color="#000099">"...
- school WiFi
- access points
- school server with Jabber server
- only one server at a time
- this is what is deployed in Peru ...
... this is the situation most of our existing laptops are
deployed in, and it's likely that upcoming deployments will be similar."</font>
I think that this scenario is good for a test, not as the intended "niche" were
the XOs must be deployed. I think the XO computers in Peru
will get better use in the WORST scenarios. A kid that lives in a town with a school that have
5 standard PCs with dialup Internet is in better condition that a kid that lives in a
town with a school with no PCs and no Internet. Who need us more? The second one. Who will
benefit more? The second one.
Yes, yes, yes. It is harder to put the XOs in the WORST scenario. And maybe 20% of the kids
that are now 6 years old will not reach the 12 years old in those "forgotten villages" in my
country (Peru). But... we must try.
<u><b>Better scenario (for developing best help with poorest children):
</b></u>There is no need to travel to the high andes to find the kids that need us more.
There are schools in the surroundings of Lima with "no light", "no tables", "no desks", "no chairs".
Every kid is sit down in a brick. The teacher
uses the wall as board. I don't know how many of this schools exists in Lima.
But for sure that they exist, dozens? Yes, no doubt.
</pre>
Ah... the last earthquake gave us another opportunity: just 3 hours
away from Lima, in the coast, no mountains,<br>
90% of the schools have been destroyed. In this "Ica" region Children
are studying (if they are studying) in any kind of <br>
temporal "school" ... in the worst conditions. There must be more than
200 schools (all sizes) destroyed there.<br>
Those kids deserve the opportunity to get a XO that can improve their
educational conditions? Yes. No doubt.<br>
<br>
I hope that upcoming XO deployments will get not the poor children but
the POOREST children in Peru.<br>
<br>
Let's keep moving.<br>
<br>
Best regards,<br>
<br>

<pre>This is something which was not completely clear to me until I talked to Wad
about it the other day, and I think other people might find it useful. It
should probably go on the wiki (assuming it isn't already there somewhere). I'd
like some feedback about where it belongs. The closest thing I've found is this
page:
<a href="http://wiki.laptop.org/go/Scenario_taxonomy" target="_blank">http://wiki.laptop.org/go/Scenario_taxonomy</a>
Any errors are my own.
There are four networking scenarios:
- simple mesh
- no access point
- no school server
- we are currently aiming to support up to 15 laptops in this case
- simple WiFi
- access points
- which tend not to handle multicast very well (1Mbit/s peak)
- no school server
- this is what G1G1 laptops will tend to encounter
- typically in the developed world
- school mesh
- no access point
- school server with Jabber server
- school WiFi
- access points
- school server with Jabber server
- only one server at a time
- this is what is deployed in Peru
Our current priority in terms of collaboration is to improve supprt for the
fourth case, as this is the situation most of our existing laptops are
deployed in, and it's likely that upcoming deployments will be similar. Our
secondary priority is improving support for the second case, as this is what
will tend happen when laptops are taken home from school.
