Welcome to the official documentation for jNetPcap SDK and jNetWorks SDK by Sly Technologies, Inc.

This site covers:

• jNetPcap SDK – High-performance Java packet capture and protocol dissection library built on libpcap/winpcap, with zero-allocation header access and advanced protocol processing.

• jNetWorks SDK – Next-generation, ultra-high-performance network capture and analysis SDK supporting DPDK, Napatech SmartNICs, and libpcap, targeting 800 Gbps+ line-rate processing.

• Common Protocols SDK – Shared protocol dissection, reassembly, decryption, and token infrastructure used by both products.

Both SDKs share the same powerful protocol processing core, enabling seamless scaling from desktop analysis to exabyte-scale capture systems.
