Bing determines bandwidth on a point-to-point link by sending ICMP ECHO_REQUEST packets and measuring their roundtrip times for different packet sizes on each end of the link.

host1 is supposed to be the nearest end of the link, while host2 is the other end.

We used the following command to test it in our localhost:
bing -c 1 -i 2 localhost 192.168.1.2
