Generally discussed herein are systems, apparatuses, and methods for creating message traffic. In one or more embodiments, a method can include receiving message characteristics of a plurality of messages to transmit to a device and transmitting, using processing circuitry, the plurality of messages to the device, wherein the plurality of messages are configured to replicate message traffic that includes the received message characteristics. The message characteristics can include a message pattern, a message density (e.g., high burstiness, low burstiness, or consistent traffic density), a message size, a message type, a message inter-arrival time, or other message characteristic.
