This environment for data collection/abstraction and visualization is very flexible since the client software has no built-in knowledge about the specifics of the data it displays. The distributed server/client environment requires only low bandwidth between the analysis machine and the user interface.
Sample analysis servers are implemented in the OCXmon environment, that collect traffic traces and process the measurement data to generate, e.g., data matrices. This matrix is displayed real-time in 3D on a remote visualization client. Such a passive monitor collects and analyzes without impact to the network by the measurement itself.
This tool is also being used as part of the active measurement
activities, where for several months NLANR has been collecting network
delays, packet loss and topology information across vBNS connected sites.
The data are presented as daily, weekly, and long-term plots as well as
network topology graphs. In addition a 3D visualisation allows animation
of a network terrain.
