Recent work on the SCIONproto implementation has focused on improving performance of the SCION router with the objective of reaching or exceeding 10 Gb/s line speeds.

The next steps in that direction are to refactor the source code to support multiple underlay implementations, and to utilise XDP (eXpress Data Path) which is a high-performance data path to send and receive packets by bypassing most of the operating system networking stack. The aim is to substantially improve real-world performance.

We are also pleased to announce that we have received a grant of EUR 30K from the NLnet Foundation’s NGI Zero Fund (which is supported by the EU Horizon Europe programme) to support this work.

The open source implementation now includes rpm packaging for multiple platforms (x86_64, 32 bit ARM and 64 bit ARM). Support for NAT traversal is being added. Many thanks to Marc Frei, Jan Luan and Tilmann Zäschke from the NetSec group at ETH Zurich for this contribution.

Finally, a thank you to martenwallewein and thomasgruebl, our new contributors this quarter.
