Packet Capturing with Clojure
summary
Shows a concrete JNI bridge to kernel‑level capture and explicit memory techniques that avoid JVM copy and GC overhead, achieving 10 GBit/s sustained capture on commodity NICs in measurements with low packet loss. Implements a binary-extraction DSL for parsing headers and payloads without intermediate allocations and a self-adaptive processing pipeline that throttles or simplifies work at runtime to stay within throughput limits. Source and tooling are practical and demonstrated end to end.
