To measure the bandwidth on a WAN circuit, we may need to pump some traffic at a rate close to the bandwidth to test whether the circuit can handle it or not. There are different traffic generator tools available such as iPerf, IXIA, and Spirent that can be used to pump different types of traffic. Other open source traffic generators such as Scapy, tcpreplay, or playcap can also be used to generate traffic.
To identify the average bandwidth utilization, follow these steps:
- Select Summary from Statistics:
The output will list the number of packets captured, Avg. MBit/sec, Avg. packet size, and so on.
- It also allows us to ...
