Looking for traces of link failures in WANs

[Idit Keidar <idish at theory.lcs.mit.edu>]

Hi,

I am looking for traces or models of the rate of link failures in
WANs. When I say "link failure" this includes a slow link that would
be detected as faulty by a time-out based failure detector (e.g.,
TCP). I am particularly interested in the probability that such link
failures will cause the network to temporarily appear non-transitive,
for example:
* A and B communicate with each other continously, 
* B and C communicate with each other continously,
* B and C temporarily disconnect from each other
  (each one detects to the link to the other as faulty).
Later, B and C reconnect.

Please CC me on the response. Thanks!

Cheers,
	Idit
