One option is that your test application supports choosing the TCP stack = and you compare "freebsd" with "bbr". One tools which supports this is uperf and here is an example how to = select the (not existing anymore) stack called "fastack"): = https://github.com/uperf/uperf/blob/master/workloads/tcp-freebsd-change-st= ack.xml The other possibility is that you set your default TCP stack before = running your test app. You can so this by executing sudo sysctl -w net.inet.tcp.functions_default=3Dbbr or sudo sysctl -w net.inet.tcp.functions_default=3Dfreebsd Then you test application can be TCP stack agnostic.
