UDP Packet Size is a misleading term

What steps will reproduce the problem?
1. Open jperf
2. Set the UDP packet size 1240 with IPv6 enabled in IP options
3. Verify that IP payload is actually 1248 (with Wireshark or tcpdump)

What is the expected output? What do you see instead?
The GUI should either ask for UDP payload size or should take the packet 
size as one including the header.

What version of the product are you using? On what operating system?
Using v2.0.2 on Windows Vista and Windows XP

Please provide any additional information below.
A UDP packet includes the header. The GUI asks for UDP packet size but 
interprets it as payload. At this point, the UDP packet size is actually 
value entered by the user + 8 bytes on the wire.

Incorrect Values for Units on "UDP Bandwidth" Field

What steps will reproduce the problem?
1. Run jperf
2. Enter any number in field labled "UDP Bandwidth"
3. Select "Kbytes/sec" in the drop-down list next to the field in step 2.

What is the expected output? What do you see instead?
Option "-b 512K" is set on iperf command line. This will yield a bandwidth
of 512 kbps (kiloBITS per second) not 512 KBps (KiloBYTES per second).
Thus, the GUI does not match the iperf implementation.

What version of the product are you using? On what operating system?
Jperf 2.0/Iperf 2.0.4/Linux(RHE)

Please provide any additional information below.

Error: no graph on server' side when report time on server is same than the client one

What steps will reproduce the problem?
1. Connect 2 computers, one running server, the other client, assuming
we're testing UDP with 10M bandwitdh, and a report time 30s on both client
and server
2. Launching the test and waiting
3. Nothing happen on server's side' graph

What is the expected output? What do you see instead?
On the output part of Jperf, we see the throughput, jitter, loss etc, but
the graph does not refreshes, but if I set the report time to 5s on server,
and 30 on client, both of them show the graph, with different scales obviously.

What version of the product are you using? On what operating system?
JPerf 2.0 and Iperf 1.70 on Windows vista/XP (client/server)

Please provide any additional information below.

save option default path

Hi,

Running jperf 2.0.2, under windows xp sp3 fr, the default path for save/restore

Is it possible to modify it to be the jperf application path ? Or add an option 
to setup this parameter (using relative path to be able to use the app path) ?

UDP Packet size should not have units assigned to the value

What steps will reproduce the problem?
1. Actiavte UDP protocol
2. Try to enter a sensible UDP packet size
3.

What is the expected output? What do you see instead?

jperf will attach the selected unit to the "-l" command. Fractions are not
allowed, so the only usable value is an MTU of 1000 bytes right now.

IMHO the only real-world usable unit here is bytes which is not selectable
at all and should at the very least be there and also be the default.

What version of the product are you using? On what operating system?

jperf 2.0.0 with iperf 2.0.4 on ubuntu 8.10.

Please provide any additional information below.

Except for some fancy fragmentation tests the packet size should be less or
equal to the MTU which is ususally in the area of 1500 bytes, so the
selection of kilos or megas really doesn't make any sense and thus I'd
completely remove the unit selection box for this setting.

Traffic direction

Sorry, I can't see any other way to ask a question.

It is not clear to me in which direction the traffic is travelling;  to the 
server, from the server or both.

I have an issue where if I swap the client and server around, the throughput 
drops significantly.  Knowing which way the data is travelling would help me 
greatly.

We expect to see the bandwidth to be reported in both directions

Please provide any additional information below.

We have tried multiple times to get the Dual testing feature to work. It 
only works intermittently and only reports the bandwidth speed in one 
direction.

When you choose UDP Bandwith the options in iperf manual are Mbits/s and in 
xjperf it appears like Mbytes/s and Kbytes/s (it will be Mbits/s and Kbits/s). 
And you can see that is wrong when the program draw the graphic
