create_transmit(messages: IList, repeat: uint32 or None = None, duration: float or None = None, max_throughput: bool = False, bitrate: float or None = None, packet_rate: float or None = None, cycle: float or None = None, packet_overhead: int32 = 4) → Transmission

Create a transmission of a burst of messages, useful to write load/stress tests.

Depending on the arguments provided, a different kind of load test is executed. The parameters max_throughput, bitrate and packet_rate can not be used together. The parameters repeat and duration can not be used together. The parameters max_throughput and duration can not be used together.

Note: The usage of the parameter max_throughput can raise OutOfMemoryException.

Parameters

• messages (IList) – The messages to transmit.

• repeat (uint32 or None) – Number of times transmitting the packets, indefinitely if value is None

• duration (float or None) – Duration of transmission the packets, indefinitely if value is None, value in seconds

• max_throughput (bool) – if True sends the packet as fast as possible, and ignore the messages timestamp

• bitrate (float or None) – If specified, the packets would be burst sent with the specified bitrate, value in bit/s

• packet_rate (float or None) – If specified, the packets would be burst sent with the specified packet rate, value in packet/s

• cycle (float or None) – If specified, how much time should pass before start sending messages again, value in seconds

• packet_overhead (int32) – How many bytes to add to each packet when using bitrate
