    局域网里,就类似于 iperf 那样点对点发包,

    但想指定速率,比如 1 Gbps,

    我是需要测不同速率下机器的功耗。

    > -b, --bandwidth n[KM]
    > Set target bandwidth to n bits/sec (default 1 Mbit/sec for UDP, unlimited for TCP). If there are multiple streams (-P flag), the bandwidth limit is applied separately to each stream. You can also add a ’/’ and a number to the bandwidth specifier. This is called "burst mode". It will send the given number of packets without pausing, even if that temporarily exceeds the specified bandwidth limit.
