How can I test/calculate it?

  • Care to share more info on your setup? Is it feasible to have a PC/server at each location with iperf or a similar tool? Sep 5, 2018 at 13:46
  • Yes we can do iPerf.

With iperf you can easily test CIR between locations.

Obviosly you need to use adeqately sized machines (enough CPU, correct ethernet interfaces size, etc.) for your link (expecially if its a >1Gbps link).

For realistic results, you should use an adequate packet size (depending on the MTU of your link) and leave it running for a couple of minutes saturating the link. This should give you a pretty close CIR measurement.

As for EIR, you can try with many iperf tests of short time (see the -t flag) with big payload (-n flag) and see if peak transfer rate differs enough from the mean rate calculated before.
