I think you have misunderstood.. what if there is no connection to the
internet even for the first laptop?
How do you provide it?

;o) Good question. In simple my mind, the connectivity and deployment
scenarios are as follows:
A) Mesh connection to each other, enabling kids to play together,
games, learning, writing, music et al. For example introducing the
chamber music masters and try to form an orchestra together ! Another
example is using a Wiki collectively to write stories or essays ....
Annotation, IM, .. All requires connectivity ...
B) At school, running school software, connected to each other and
to the class room server
C) And of course the traditional scenario, at school or home,
connected to internet.
D) I have only very limited exposure, but methinks, Internet is
more pervasive. And the hope is that Internet will reach more and more
into areas (OLPC being one of the catalysts)
Thoughts ?

All very well guys - but go back one stage
What are you going to connect it too?
I want to put them in a South African township of 1 million
people, so the school kids can use them.. but there is no
internet connection.
And if thats in a township.. what chance do you stand in rural areas?
The mesh has to link into something.
So yes, technically interesting.. but?

Interesting question. Actually I was also thinking about the same
issue ! From my (limited) view :
a) There will be py level interfaces - dials, gages, switches
and control knobs and a coherent programming model. We do
need APIs at
that layer.
b) But the majority of the work would be done at the L1/2/3.
c) The mesh (802.11s) will be implemented as a Layer1/L2
artifact
d) The mesh mobility networking primitives would be more of
OLSR/AODV/DYMO (more of DYMO/OLSR than AODV) than normal
OSPF. Could
be OSPF v3 with mobility as well.
e) We also would need to work with D-Bus, the Avahi
layer(mDNS, local network forming et al) as well as the twisted
framework (if that is part of the distribution)
f) And we should not forget IPv6 !

Subject: [OLPC Networking] Mesh network?
Has there been a clear plan on how to achieve the mesh network?
Will it be some python script/framework that acts like a router,
maintaing a routing table and OSPF of available nodes? Or
is even that
too high-level, and the mesh capabilities will be done at
some lower
layer?
I am generally interested in how it will be
implemented, either from
scratch or from existing technology.
