Details

udpst is a versatile UDP speed test client / server application.
It is highly configurable but in minimalistic mode as easy to use as iperf, see the Examples.

udpst supports IPv4 and IPv6 and can even run tests over SSL / TLS.

The test results are very verbose and separate for OSI layer 1-3, with round trip time and packet loss statistics.
They can even be exported in different JSON formats. This is really an industry grade tool.

The project has the cryptic name obudpst (Open Broadband-UDP Speed Test) and has its Github Repo.
Quoting its description: "OB-UDPST is a client/server utility to do UDP-based IP capacity measurements
(see TR-471 for details)".

See also libavmudpst.so, udptest, udpspread.

UDP Speed Test
Usage: udpst [option]... [server]

Specify '-u' or '-d' to test as a client (a server parameter is then required),
else run as a server and await client test requests.

Options:

(c)    -u|-d        Test Upstream OR Downstream as client
       -4           Use only IPv4 address family (AF_INET)
       -6           Use only IPv6 address family (AF_INET6)
(s)    -x           Execute server as background (daemon) process
(e)    -e           Disable suppression of socket (send/receive) errors
       -v           Enable verbose output messaging
       -s           Summary/Max output only (no sub-interval output)
       -f format    JSON output (json, jsonb [brief], jsonf [formatted])
(j)    -j           Disable jumbo datagram sizes above 1 Gbps
       -T           Use datagram sizes for traditional (1500 byte) MTU
       -D           Enable debug output messaging (requires '-v')
(m)    -X           Randomize datagram payload (else zeroes)
       -S           Show server sending rate table and exit
       -B mbps      Max bandwidth required by client OR available to server
       -r           Display loss ratio instead of delivered percentage
       -i count     Display bimodal maxima (specify initial sub-intervals)
(c)    -o           Use One-Way Delay instead of RTT for delay variation
(c)    -R           Ignore Out-of-Order/Duplicate datagrams
       -a key       Authentication key (32 characters max)
(m,v)  -m value     Packet marking octet (IP_TOS/IPV6_TCLASS) [Default 0]
(m,i)  -I [@]index  Index of sending rate (see '-S') [Default @0 = <Auto>]
(m)    -t time      Test interval time in seconds [Default 10, Max 3600]
(c)    -P period    Sub-interval period in seconds [Default 1]
       -p port      Port number used for control [Default 25000]
(c)    -A algo      Rate adjustment algorithm (B - B) [Default B]
       -b buffer    Socket buffer request size (SO_SNDBUF/SO_RCVBUF)
(c)    -L delvar    Low delay variation threshold in ms [Default 30]
(c)    -U delvar    Upper delay variation threshold in ms [Default 90]
(c)    -F interval  Status feedback/trial interval in ms [Default 50]
(c)    -c thresh    Congestion slow adjustment threshold [Default 3]
(c)    -h delta     High-speed (row adjustment) delta [Default 10]
(c)    -q seqerr    Sequence error threshold [Default 10]
(c)    -E intf      Show local interface traffic rate (ex. eth0)
(c)    -M           Use local interface rate to determine maximum
(s)    -l logfile   Log file name when executing as daemon
(s)    -k logsize   Log file maximum size in KBytes [Default 1000]

Parameters:

      server       Hostname/IP of server (or local interface IP if server)

Notes:

(c) = Used only by client.
(s) = Used only by server.
(e) = Suppressed due to expected errors with overloaded network interfaces.
(j) = Datagram sizes that would result in jumbo frames if available.
(m) = Used as a request by the client or a maximum by the server. Client
      requests that exceed server maximum are automatically coerced down.
(v) = Values can be specified as decimal (0 - 255) or hex (0x00 - 0xff).
(i) = Static OR starting (with '@' prefix) sending rate index.

Examples

7530 fw 7.39 examples:

Server

First of all we need the server. The minimalistic way is calling udpst without arguments to run the server in foreground: 

root@fritz0:/var/mod/root# udpst

UDP Speed Test
Software Ver: 7.4.0, Protocol Ver: 8-9, Built: Sep 13 2022 15:01:45

Mode: Server, Payload Default[Max]: 1222[8972], Authentication: Available, SendMMsg(): Available
^C

This provides informative output but blocks the shell so we Ctrl-C it to run it in background: 

root@fritz0:/var/mod/root# udpst -x

root@fritz0:/var/mod/root# ps | grep udpst

2755 root      4004 R    udpst -x
3543 root      1624 S    grep udpst

The help shows no option to stop the background server but killing it seems to work gracefully: 

root@fritz0:/var/mod/root# killall udpst

root@fritz0:/var/mod/root# ps | grep udpst

3568 root      1624 S    grep udpst

Client

The client can either perform a downstream or an upstream test. Bidirectional test is not supported.

Downstream test:

This minimalistic call performs a 10 seconds downstream test: 

root@fritz0:/var/mod/root# udpst -d localhost
