1Netsend and Netreceive
4This pair of binaries is used to fixed rate UDP performance testing.
6The netreceive tool consists solely of a UDP packet sink bound to a
7specified UDP port. Packets received on its port are copied to user space
10The netsend tool acts as a packet source, generating packets of the
11specified size at the specified rate to a target IP address and port
14 netsend [ip] [port] [payloadsize] [rate] [duration]
16The payloadsize field specifies the size of the UDP payload, not the total
17packet size, which will also include a variety of headers (typically,
18ethernet, IP, and UDP).
20The rate indicates the number of packets/second to attempt to deliver.
22The duration is the duration of the run in seconds.
24The netsend tool will wait for around two seconds to synchronize with the
25wall clock for timing purposes. It will then busy-wait between packet
