[Csci551-talk] random is not that random

[Affan, Syed]

Interesting. We really hadnt thought of that (this randomization problem
while choosing being not "random"). Off the top of my head, i dont see
any reason why not to set of 8 requests at the same time. But if some
one can come up with a better way to randomize.. it would be nice to
share with all. 
 
 

Best Regards,

When I loop for max of 8 segments and pick at random a segment that I
still need,
I get at most 2 different random values.  If a put a sleep after each
rand call, I get a
better variety.  Since I am in the loop selecting a new random segment
and a
random volunteer from whom I can download, I don't wait to get any
responses,
I just blast off the requests.  Is this incorrect? Are we suppose to
delay our
requests, or is ot fine to have a short sleep after each rand call in
this loop?
Rand seems to be working better for loss as it does not occur at this
short
intervals.
