3 | # The purpose of this experiment is to benchmark the node CPU
|
---|
4 | # capabilities in terms of the maximum offered load that it can
|
---|
5 | # generate and consume on the wired Ethernet link
|
---|
6 |
|
---|
7 | # It has one sender and one receiver
|
---|
8 | # Sender, Receiver - Wired interface
|
---|
9 | # UDP flow at 500Mbps
|
---|
10 | # Receiver reports throughput, jitter and packet loss per second
|
---|
11 | # Iperf traffic generator
