Determining which layer of the networking stack contains a bug is one of
the most challenging problems we have had with recent network debugging.
One lead developer recently proposed running all our tests twice, over the
wireless network and also using RJ-45 USB dongles, in order to help
classify these problems. Running tests on other hardware, or in virtual
machines, would also be worthwhile.
It should be noted that there are already two active OLPC networking testbeds:
If your project this summer requires XO's, I suspect OLPC will be able to
provide you with several. However, the main network testbed has over 100
XOs, which is necessary for testing scalability bugs (of which there are
many). As that page suggests, essentially no automation has yet been
achieved on the network testbeds. If you develop a way to perform
automated testing on the network testbeds, OLPC will happily adopt it.
