Network Emulation Tools

In general, it is difficult to assess performance of distributed applications and protocols before they are deployed on the real network, because the interaction with network impairments such as delay is hard to predict. Therefore, researchers and practitioners often use emulation to mimic deployment (typically wide-area) networks for use in laboratory testbeds.

NISTnet and 'netem' are network emulation software that can be run on Linux machines. In particular, they can be used to introduce delays to packets, thereby simulating a long(er) distance network.
