[spring] SRv6 SID Compression pcaps, Wireshark, and P4TG

[Fabian Ihle <[e-mail]>]

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.

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.

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

See you in the WG session!

Best,

Fabian
