Mesh Testing: Difference between revisions

Revision as of 21:06, 21 February 2008

This page describes the network testing that will be performed on Monday Feb 25th at 1cc.

Measurements to make during each test:

Spectrum utilization -- estimate rate, integral, vs. idle
Remaining bandwidth -- attempt to download a large file on one machine during test, record time taken.
Total # of laptops seen on mesh view on all numbers (should be n^2).

Workloads -- tests to perform, along with their quantitative metrics:

Idle load.
Every machine coming out of suspend.
Every machine trying to register with school server -- Number of machines that failed the first attempt, failed second attempt, etc.
Ricardo's web spider -- record rates
Read -- if one laptop shares a PDF, how many laptops fail to retrieve it?
Distance
Write -- automate pressing 1 character every second, look at received rate/update time, increase number of participants
olpc-update -- number of machines upgraded in 1 hour

Ideas to investigate:

+Ideas to investigate:
+* Presence:  Benchmark bandwidth use of Avahi vs. Cerebro vs. no presence?
+* Collaboration: Benchmark switching from multicast to unicast?
