I have a 2nodes Cassandra ring on ec2 (, in the same zone (east-1). How can I introduce a 3 seconds delay for all cassandra-related network communications between them? I found 'dummynet' via Google as a possible solution but I haven't been able to figure a way.

This probably belongs on Serverfault, but the normal way on Linux would be with the network emulator queuing discipline. linuxfoundation.org/collaborate/workgroups/networking/netem –  derobert Jun 8 '11 at 20:58
