[Olsr-dev] Fwd: "Mesh" Dreams = OLSR

[L. Aaron Kaplan]

Hi!

Reuben asked me to forward this to the olsr list. 
Maybe OLPC gets a fresh start with mesh + OLSR. Who knows...

Now think of an XO that has two USB Wireless Adapters each connected respectively to one of those channels. This central XO also has a third USB ethernet dongle or a 3G wireless modem attached to it. Consider how this simple setup could provide Internet to everyone in the school. Consider the ability to actually create "Mesh Portal Points," that allow one connection to provide an Internet connection to many hops down the line.

Over the past few months, I have tested and built small networks around my neighborhood to consider the feasibility of such software. Now I realize there is a difference between small and large networks but I think it is something we should consider.

> -Summary: layer 2 is king for scalability , only then do you need to look at layer 3 optimizations (and with OLSR.org we already took care of that part"
