This year, we are celebrating 30 years of Studenten Net Twente. For this occasion, we are hosting another edition of SNTPings!

The University of Twente graceously agreed to provide us with a dedicated 40Gbps link, and host us on displays all over the campus!

Please be considerate of others. Any kind of abuse, like inappropriate content or or exceedingly high packet rates will lead to blacklisting of your entire /64.

The UT has provided us with a 40 gigabit connection. This is fed from a tap on the 100g uplink to SURF and a 10G internal connection. A SNT server with a 40gbit network card ingests incoming ICMPv6 packets using the DPDK framework.

The colors are extracted and put into an OpenCV canvas which is the rendered to a MediaMTX media server using gstreamer for further distribution.

There are two main limitations: The chosen network card (and other network equipment) is rated for 40gbps, but cannot easily keep up with the packet-per-second load. Secondary, the use of x264 software encoding significantly reduces the quality of the stream. A live-updated image with better quality is supplied here.
