Unable to run iperf for bandwidth testing

[Amar Sinha]

Hi,

I cannot run iperf for bandwidth testing on the handover code; however, I can ping successfully.

[Ramon Fontes]

How can we reproduce the issue?

Please also provide a detailed explanation of the expected result, including the anticipated outcomes and their underlying reasoning.

[Amar Sinha]

Respected Sir,

I wanted to check bandwidth and throughput between h1 and sta1. To do this I opened xterm terminals of h1 and sta1.

After this, I used the command "iperf -s" for a server listening on h1. Then, I executed "iperf -c 10.0.0.2" on sta1 to send traffic to h1.

Dear Amar,

It seems that the P4 code isn't currently processing TCP/UDP packets,
correct? If that's the case, wouldn't the behavior you mentioned be
expected?

[Amar Sinha]

Respected Sir,

I have edited the file as attached but it shows same error.

[Ramon Fontes]

Could you describe what exactly you did, step by step?

Respected Sir,

These are the steps-

• TCP/UDP header definitions were added to enable TCP/UDP packet processing.
• Implemented Bloom filter logic to check if a flow rule exists.
• Separate tables for TCP/UDP forwarding were added. Allow flexible handling based on the transport protocol.

[Ramon Fontes]

Did you compile the p4 code and run it?

No Sir. Can you please guide me through the steps? It would be invaluable.

[Ramon Fontes]

Dear Amar,

There's a lot to learn before working with P4. Unfortunately, I can't guide you through every step.

Respected Sir,

Earlier, I have worked on mininet when I was persuing SDN course. I am confused about using the p4 compilation commands in containernet. I tried to use the p4c commands and also the bm2 commands available in the documentation but was unable to execute them. I would really appreciate it if you could guide me, sir.

[Ramon Fontes]

p4c is an independent compiler and has no connection to Mininet or Containernet. If you're having trouble running p4c, the issue is unrelated to Containernet.
