+"""Traffic profile for T-rex advanced stateful (astf) traffic generator.
+
+Traffic profile:
+ - Two streams sent in directions 0 --> 1 (client -> server, requests) and
+   1 --> 0 (server -> client, responses) at the same time.
+ - Packet: ETH / IP / TCP
+ - Direction 0 --> 1:
+   - Source IP address range:      192.168.0.0 - 192.168.15.255
+   - Destination IP address range: 20.0.0.0 - 20.0.15.255
+ - Direction 1 --> 0:
+   - Source IP address range:      destination IP address from packet received
+     on port 1
+   - Destination IP address range: source IP address from packet received
+     on port 1
+
+This is a profile for CPS tests, it only sets up and tears down TCP session.
+No delays, no data transfer.
