StarOS allows the runtime loading of plugins. All StarOS builds include a “default” baseline plugin.
This feature is currently used to dynamically update the detection logic used to filter P2P applications via the
Application Detection and Control (ADC) feature.
Application Detection and Control (ADC) feature.
Patching is the process used to install a plugin as an incremental update to a StarOS release. One plugin can be provided

via the internet or by other means (USB stick, CD, etc.).
A plugin is a functional software entity that provides incremental updates to a pre-existing StarOS software component.
Plugins have the characteristic of being dynamically loadable at runtime and do not require a system restart. A plugin
has a name and one or more versions. All plugin names are known to the system at product release.
