I had not thought of adding latency to the network interface. I have skimmed descriptions of how to do this with iptables (or ipchains - I can't remember which is the standard now) - so it sounds plausible. Whether this is within my capabilities is another matter.
I really do not follow the delegator approach. Is this something I would patch into Zookeeper ? Or the client ? regards, Martin On 24 February 2010 18:40, Ted Dunning <ted.dunn...@gmail.com> wrote: > I do believe that it is relatively easy to set up high latency/high error > network interface clones in Linux.
