The traffic generation rate can be modified by changing application properties. Note that the generation rate should be less than or equal to the service rate for steady-state simulation, where the service rate is defined as the data rate supported by the Bottle-neck link. (Users can refer to the queuing theory experiment from experiment manual available at Experiment Manual to understand this better)
The traffic generation rate can be modified by changing the application properties. For a steady-state simulation, the traffic generation rate should be less than or equal to the service rate, where the service rate refers to the maximum data rate supported by the bottleneck link. Users can refer to the queuing theory experiment in the NetSim Experiment Manual available at User Manual for a better understanding of this concept.
The CBR (Constant Bit Rate) application generates traffic at a constant rate. Increasing the packet size increases the traffic generation rate, while decreasing the inter-arrival time also increases the generation rate. The traffic generation rate is calculated using the following formula:
Generation Rate(Mbps) = ( (Packet size(bytes)∗8)) / (Inter_arrival_time(µs) )
These parameters can be configured in the Application Traffic Properties section of the NetSim UI, as shown below.
