<li>Added so called barrier functionality, which is a set of commands to easy implement a barrier. A barrier is some point in time during execution of a test which if reached can trigger some action.

The outcome of the performance measurement was 20 MByte/s for packet size of 65000 bytes.
For this measurement the TNG layer was using tcp only, because there was an unfixed bug, if running tcp and udp in parallel.
