Hi all,
new to the spring mailing list, so forgive me if this has been asked
before. I'm looking for example PCAP files of the different SRv6 SID
compression methods. Does anyone have such captures and would be willing
to share them? Also, is there an existing Wireshark dissector for SRv6
compression formats? If not, I’d be interested in collaborating to
develop one.
Hi Fabian,
I think there is already something, I am putting in cc: Andrea and Paolo
working in my team
I hope we'll give you a more precise answer in the next days (depending
on vacation periods of Andrea and Paolo...)
For context: I am a PhD student developing the open-source traffic
generator P4TG. Our traffic generator achieves 10x 400 Gbit/s of traffic
generation with various customizable protocol stacks (including SRv6
with 3 uncompressed SIDs!). Further, P4TG includes many measurement
functions, such as TX/RX rates, RTT histograms and much more, all
rendered in a nice frontend, or available in the REST API. I plan to
extend P4TG with support for generating traffic using configurable SRv6
SID compression methods. To validate my implementation, I’m looking for
"ground truth" PCAPs.
sounds interesting :-)
having worked with Linux implementation of SRv6, it should be relatively
easy to generate such "ground truth" PCAP (of course as long as we can
take Linux implementation as ground truth... anyway we can surely help)
P4TG is built for the Intel Tofino (2) hardware, which is EOL. However,
the SDE has been open sourced which allows you to run P4TG without the
Intel NDA (more information here: https://github.com/p4lang/open-
p4studio/issues/101). Hardware is still acquirable.
If the P4TG project sounds interesting to you , here's some more
information: https://github.com/uni-tue-kn/P4TG
we'll give a look
ciao
Stefano
See you in the WG session!
Best,
Fabian
