+The tests are running on 2-node testbeds: 2n-tx2. The uni-directional tests
+are partially addressing a weakness in 2-node testbed setups with T-Rex as
+the traffic generator. With just one DUT node, we can either encrypt or decrypt
+traffic in each direction.
+
+The testcases are only doing encryption - packets are encrypted on the DUT and
+then arrive at TG where no additional packet processing is needed (just
+counting packets).
+
+Decryption would require that the traffic generator generated encrypted packets
+which the DUT then would decrypt. However, T-Rex does not have the capability
+to encrypt packets.
