Module Meter Throughput Meter

The throughput meter module measures the throughput of the traffic. The throughput in bit/s and byte/s as well as packets/s is computed over a sliding window of a configurable time. Measurements are taken at a configurable interval.

By changing the window size, the degree of filtering of the values can be controlled. Using a small window size results in high frequency variations in the generated statistics, while using a large window size smoothes them out. Additionally, the precision of the values is proportional to the window size. Therefore, for a window size of 1000 ms, a precision of 1 packet/s or 1 byte/s can be achieved. For a window size of 100 ms, the precision reduces to 10 packets/s or 10 bytes/s. Changing the interval only influences the sampling frequency of the generated statistics, but does not change the values itself. However, setting the interval too low might have a negative effect on the emulation performance.
