udp_bw_mon(1)

NAME

udp_bw_mon - Client program from the monitor that gives an estimate from the UDP bandwidth in the route between two end nodes

SYNOPSIS

udp_bw_mon   [Option [...]]

DESCRIPTION

The program udp_bw_mon is the client from the monitor that gives an estimate from the UDP bandwidth in the route between two end nodes. The corresponding server program is udp_bw_resp(1).

OPTIONS

The following options can be specified:

-B BinWidth
Set the bin width of the remote histogram. The default is 1.
-G
Get remote information.
-H
Get remote histograms.
-L
List the output values in outlined columns. Each value is preceded by a short description. See also the option -q.
-M LowLimit
Get the low limit of the remote histogram. The default is 0.
-P PrecedenceBit
Set the precedence bit - shift left by 9.
-S BufferSize [bytes]
Specify the receive and send buffer sizes. The default is 65535 bytes.
-T TOSBits
Set the TOS bits - shift left by 1.
-d DestIPAddr
Set the destination IP address in the format a.b.c.d.
-e ResponseLengthMax
Set the maximum length of the response message used for looping over response length. The default is 0.
-i IncrementLength
Set the size to increment the response message. The default is 8.
-l LoopCount
Set the # times to loop over the message loop. See also the option -i. The default is 1.
-n OnTime [micros]
Send a shape time interval when traffic will be send. This option is only effective when also a non-zero value at the option -o has been specified. With this option the Pentium oscillator is used to calculate all data rates which may result in slightly different values. Default no shaping is used.
-p PacketLength [bytes]
Set the length of the mock data packet. The default is 64 bytes.
-o OffTime [micros]
Send a shape time interval when no traffic will be send. This option is only effective when also a non-zero value at the option -n has been specified. With this option the Pentium oscillator is used to calculate all data rates which may result in slightly different values. Default no shaping is used.
-q
Quiet mode - only print results. See also the option -L.
-t TestTime [s]
Set the test time to loop over the message loop in the place of specifying a number (option -l). Every 100 loops there will be checked if the test time has been passed. Default a # times to loop over the message loop is used.
-u Port
Specify the UDP port. The default is 14233.
-w WaitTime [micros]
Set the time to wait between packets. The default is 0 micros.
