Comment (by cypherpunks):

 > There could be another cause: for example suppose all the DPI boxes
 count connections to each IP address and upload the logs to a central
 place, then the firewalls only apply their timing/entropy heuristics to
 popular destinations. It wouldn't surprise me if a firewall vendor were
 uploading customer connection logs in order to do data mining on them.

 They no need to send it to central place, box can to count connections
 locally to skip all new addr:port. But then why need to count entropy
 every time for already known addr:port? Why so complex?
