+ * @brief base test case for transport traffic manipulation implementation
+ *
+ * This test case will setup 2 peers and connect them, the first message
+ * will be sent without manipulation, then a receive delay of 1 second will
+ * be configured and 2 more message will be sent. Time will be measured
*
- * This test case serves as a base for tcp, udp, and udp-nat
- * transport test cases. Based on the executable being run
- * the correct test case will be performed. Conservation of
- * C code apparently.
+ * In addition the distance on receiver side will be manipulated to be 10
