Valentin

Site Reliability Engineer + Software Engineer in 5G Core Networks

• 🔭 I’m the lead developer and maintainer of PacketRusher, a high-performance tool dedicated to the validation of 5G Core networks.
• 🚀 I’m also working on OxiRush, a set of Rust libraries for fast prototyping and testing of 5G and LTE/EPS core-network functions:
  • oxirush-nas — 5GS and EPS NAS codec for TS 24.501 and TS 24.301, with validation and NAS security.
  • oxirush-security — 5GS and EPS key derivation, ciphering and integrity algorithms, and SUCI, per TS 33.501 and TS 33.401.
  • oxirush-ngap — 5G NGAP codec for TS 38.413, generated from ASN.1.
  • oxirush-s1ap — LTE/EPS S1AP codec for TS 36.413, with the same API as oxirush-ngap.
  • oxirush-sctp — async SCTP sockets for Tokio on Linux.
  • oxirush-gtp-u — GTP-U codec, endpoint and test UPF for TS 29.281, with an eBPF fast path.
• 🌱 My interests are: Rust/Go/Java, eBPF, k8s/OpenShift, Networking, Linux, 5G Core networks
• 🌐 I operate the hobbyist IPv6 network AS212856
