        * param **traffic_type**: One of the supported traffic types,
-         e.g. **rfc2544_throughput**, **rfc2544_continuous**
-         or **rfc2544_back2back**.
-       * param **frame_rate**: Defines desired percentage of frame
-         rate used during continuous stream tests.
+         e.g. **rfc2544_throughput**, **rfc2544_continuous**,
+         **rfc2544_back2back** or **burst**.
        * param **bidir**: Specifies if generated traffic will be full-duplex
          (true) or half-duplex (false).
+       * param **frame_rate**: Defines desired percentage of frame
+         rate used during continuous stream tests.
+       * param **burst_size**: Defines a number of frames in the single burst,
+         which is sent by burst traffic type. Burst size is applied for each
+         direction, i.e. the total number of tx frames will be 2*burst_size
+         in case of bidirectional traffic.
        * param **multistream**: Defines number of flows simulated by traffic
          generator. Value 0 disables MultiStream feature.
        * param **stream_type**: Stream Type defines ISO OSI network layer
