Jpcap

Jpcap is a powerful software toolset for network packet capture and analysis that includes a protocol library and visualization feature. This set of Java classes simplifies the complexities of network packet capture by abstracting many network packet types and protocols into organized classes. One of the core features of Jpcap is that it is designed to hide the low-level details of network packet capture so that users can focus on the task at hand.

Internally, Jpcap implements bindings to the libpcap system library through the Java Native Interface (JNI), which is essential for users to capture user-level packets. Therefore, it is essential to have libpcap installed on your system in order to use Jpcap. Users can also benefit from a small shared-library component that wraps libpcap along with a collection of Java classes that Jpcap provides.

Additionally, Jpcap offers multiple packages to help with the network simulator, such as the "capture" package that contains the core capture system, the "net" package that contains abstractions for many network packet types and protocols, and the "simulator" package that contains a network simulator. Notably, Jpcap is licensed and distributed under the Mozilla Public License 1.1 (MPL 1.1), which is intended to offer more extensive flexibility in the use of the software.

Overall, Jpcap is an exceptional software tool that provides a useful interface and system for network packet capture and modeling, making it an excellent tool for software developers and network administrators alike.
