amp udpstream
amp-udpstream - AMP standalone UDP jitter test
amp-udpstream -s [options]
amp-udpstream -c server [options]
amp-udpstream is the standalone version of the amplet2(8) UDP jitter test. It sends streams of UDP packets between two endpoints (either one being this standalone test or a running instance of amplet2(8)) and reports on the jitter, latency and loss observed. These values can be used to calculate Mean Opinion Scores for possible Voice Over IP streams.
-p, --port port
Set server control port to connect to/listen on to be port. The
default is 8815.
-I, --interface iface
Specifies the interface (device) that tests should use when sending
packets. By default the interface will be selected according to the
routing table.
-4, --ipv4 a.b.c.d
Specifies the source IPv4 address that tests should use when sending
packets to IPv4 targets. This address must belong to one of the
interfaces. By default the IPv4 address of the outgoing interface will
be used.
-6, --ipv6 a:b:c:d:e:f:g:h
Specifies the source IPv6 address that tests should use when sending
packets to IPv6 targets. This address must belong to one of the
interfaces. By default the IPv6 address of the outgoing interface will
be used.
-s, --server Run in server mode.
-c, --client host
Run in client mode, connecting to host.
-d, --direction dir
Magic value describing direction. Valid values are 0 (client to server),
1 (server to client), 2 (client to server then server to client), 3
(server to client then client to server). The default is 2.
-D, --delay usec
Delay between sending consecutive packets in the stream. The default is
20000usec (20ms).
-n, --packet-count count
Number of packets to send in the stream. The default is 11.
-P, --test-port port
Perform the actual throughput test using port port. The default is
8816.
-Q, --dscp codepoint
IP differentiated services codepoint to set. This should be a string
representing a 6-bit value in binary, octal, decimal or hexadecimal, or the
short name of a predefined, commonly used codepoint. The default is 0.
-r, --rtt-samples N
Reflect every Nth probe packet to provide an estimate of the round
trip time. At large packet volumes or with low delay between packets,
you may want to lower this to reduce load on the network and/or hosts.
The default is to use every packet.
-z, --packet-size bytes
Specifies the total number of bytes to be sent per packet (including
headers). The default is 100 bytes.
-h, --help Show summary of options.
-v, --version Show version of program.
-x, --debug Enable extra debugging output.
amp-udpstream -c <target> -d 1 -D 10000 Run a server to client test with 10ms between packets in the stream.
amp-udpstream -c <target> -d 3 -n 1000 -r 2 Run a server to client test, then a client to server test, both streams having 1000 packets, using every second packet as an RTT estimate.
amplet2(8), amplet2-remote(8), amp-icmp(8), amp-trace(8), amp-dns(8), amp-throughput(8), amp-http(8), amp-tcpping(8).
