extensible deep packet inspection library - shared library
nDPI is a ntop-maintained superset of the popular OpenDPI library. Released under the LGPL license, its goal is to extend the original library by adding new protocols that are otherwise available only on the paid version of OpenDPI. . nDPI has also been modified to be suitable for traffic monitoring applications, by disabling specific features that slow down the DPI engine while being them un-necessary for network traffic monitoring. . With nDPI, it is possible to both detect known protocols on non-standard ports (e.g. detect http non ports other than 80), and also the opposite. . This package contains the shared library.
