By default, netperf will open two connections - the first is the control 
connection.  This runs between netperf and netserver and is how netperf 
tells netserver what to do.  This is always a TCP connection.

The second is the "data connection."  Depending on the protocol/test it 
may not be a "real connection, but it will be another set of sockets.

So, if your simple protocol can run at the same time as a TCP 
connection, you should be all set.  All you need to do is 
cobble-together a nettest_yourprocol.c file and put your test in there 
(perhaps heavy cut and paste from nettest_bsd.c and a test similar to 
what you want to do) and some stuff in netsh.c and perhaps netserver.c 
etc and you should be good to go.

happy benchmarking,
