Powerful packet filtering
Easily create complex filters with the filter editor. Ubiqua features the ability to filter packets and show only the ones that fulfill certain logical criteria. Filters can be saved and shared with other Ubiqua users.
Automatic packet field monitoring
Never lose track of important information! You may configure the Watch View to automatically find and display variables of interest in the packet log as you traverse your captures.
Graphical topology visualization
Graphical visualization of the network topology as interpreted by the current capture data, with quick access to individual node properties. Additionally, nodes may be named and positioned over a custom background image such as a blueprint to easily keep track of devices.
