THE ENGINE UNDER THE HOOD

Packet Capture SDKs
for Java

Two SDKs. One for maximum performance. One for maximum portability. Both share the same token-stream architecture — the same foundation that powers ExaViewer, ExaCapture, ExaVolume, and the Vantage Platform.

Same Foundation. Different Scale.

Both SDKs share the same protocol dissection engine, spec lifecycle, and token stream format. Start where your requirements are today. Upgrade without rewriting.

Start with jNetPcap. Scale to jNetWorks.
Same token stream. Same dissection engine. No rewrite.

Both SDKs emit the same 16-byte analysis tokens from the same protocol stack. Your application logic, analyzer plugins, and token consumers all carry forward when you upgrade backends.
