Abstract

This paper explores the use of eBPF technology for DNS traffic optimization. By implementing a system based on eBPF, XDP, and the Rust programming language, real-time inspection and manipulation of network packets is demonstrated. Theoretical foundations are presented, key solution components are described, results are evaluated, and future development directions are proposed, including the integration of heuristics and artificial intelligence for DNS cache optimization.
