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.
