jNetPcap SDK

An easy to use java software package, for developing network applications that need to capture packets from a live network or a file. A full featured protocol decoder breaks down the packet structure, allowing the user a simple access to packet content without having to understand the very complex protocol specific rules.

Additional features:

• Transmit raw data-link frames from java to a live network
• Capture and save packets to a file for offline processing
• Native machine level performance
• No-copy packet captures ^[1] - ensures that once a packet is captured and stored in kernel memory, your java application receives that packet with no further copies for maximum performance
• Full API support for libpcap and WinPcap features

Best of all! jNetPcap is completely free under LGPL open-source licensing terms. Various support options are available as well. A great, no charge, community based support is available on main project website. For companies that require more, Sly Technologies is pleased to offer various commercial support options at affordable price points.
