nDPI
开放且可扩展的LGPLv3深度包检测库。
nDPI是流行的OpenDPI库的ntop维护超集。它是根据LGPL许可发布，其目标是通过添加新协议来扩展原始库，这些协议否则仅在OpenDPI的付费版本上可用。除了Unix平台，我们还支持Windows，以便为您提供跨平台的DPI体验。此外，我们还对nDPI进行了修改，使其更适合流量监控应用程序，方法是禁用降低DPI引擎速度的特定功能，而这些功能对于网络流量监控不是必需的。
无论使用哪个端口，ntop和nProbe都使用nDPI来添加协议的应用层检测。这意味着既可以检测非标准端口上的已知协议(例如，检测80以外的端口上的HTTP)，也可以检测相反的协议(例如，检测端口80上的Skype业务)。这是因为现在port=application的概念不再成立。
我们正在不断扩展nDPI，到目前为止支持的协议有很多，包括：
元数据提取
NDPI不仅检测应用程序协议，还报告与流相关的元数据，如URL、TLS证书、操作系统等。下面是可以从流中提取的元数据的示例。

...流量分析
nDPI不仅提供DPI功能，还包括流量分类和分析的各种功能，使你能够创建你的应用程序，而不必实现复杂的分析功能，因为这些功能已经由nDPI提供（阅读更多）。

ETA（加密流量分析）
nDPI允许你从加密的通信中提取元数据，并对加密的通信进行分类。
文档
您可以参考nDPI手册的文档页面。
请您贡献！
由于协议（尤其是P2P）经常更改，因此DPI是一项耗时的活动。这意味着有必要不时更新代码并添加扩展名。我们会鼓励任何人帮助我们添加或增强新协议：我们会将您的贡献放在我们的SVN上，并免费提供给所有人。实际上，我们决定选择nDPI而不使用原始库的主要原因是，OpenDPI背后的公司从未回复过我们提供的将我们编码的扩展合并到原始源代码中的提议。
许可证license
当您构建ntop和nProbe时，将自动下载nDPI。但是，没有什么可以阻止您将其用作独立的DPI库。可以从下载部分下载源代码。
