Some questions about the output

Open zhibindaxia opened this issue 6 years ago • 14 comments

Can you tell me where the content in the mix.tr file comes from?What is the meaning of qFb in the figure below?Thank you. image

It is generated from here:

https://github.com/bobzhuyb/ns3-rdma/blob/e8a27d02bfe5ef0aec189c7d1a401547dbd8fbad/src/point-to-point/model/cn-header.cc#L123

If I remember correctly, it's for counting how many ECN marks the receiver has received in the last time period. This is not used for now (I experimented with it but later did not really use it)

If qFB is output, can I think there is congestion?

zhibindaxia avatar Dec 12 '18 13:12 zhibindaxia

yes

Hi,I read the papers Congestion Control for Large - scale RDMA Deployments, SIGCOMM '15 (DCQCN) , what would you like to use tool to draw the figure? image

Can I know which line of code calls these two functions? image image

zhibindaxia avatar Dec 18 '18 11:12 zhibindaxia

I used gnuplot for those figures.

The function is called by one of the trace functions, probably in qbb-net-device.cc, but I don't remember which function it is.

Thank you.

Sorry to bother you again, but did you generate these images by calling GnuplotHelper code in visual studio2015?I was unable to call GnuplotHelper in visual studio2015. image

zhibindaxia avatar Dec 25 '18 04:12 zhibindaxia

No. I parsed the trace output and plotted the figures using native gnuplot.

Did you get a graph of the throughput of the nodes from the mix.tr file?I'm a little confused about that.

zhibindaxia avatar Dec 25 '18 07:12 zhibindaxia

Yes. You need to write some simple scripts yourself.

bobzhuyb avatar Dec 25 '18 08:12 bobzhuyb

If it is convenient for you, could you give me a simple example for my reference?Thank you.

image Can you tell me what these values mean and how they relate to each other?

zhibindaxia avatar Dec 27 '18 06:12 zhibindaxia

image Could you tell me the function of this function？
