Vving is a simple to use front-line diagnostic tool to look at network performance. Its user interface is shown below:

Every second Vving sends a signal to a remote computer and waits to receive it back in an echo fashion. It then graphs how long it took for the echo to return and what portion of the echo returned. The graph is updated for every echo received, which is once per second by default. Running it all day long produces over 80 thousand points that need to be plotted in real time. Additionally, the sample rate can be adjusted from 1 to 120 seconds in order to increase or decrease network activity.

Vving is different from other similar applications because it will actually plot all the data to the screen without any smoothing or averaging. That means, for instance, if your computer's Internet connection temporarily degrades for a second or two then you will see it in Vving's output as a spike in the signal. Such things happen occasionally as computer hardware momentarily freeze and it is really not a good thing. For some data acquisition purposes the spike is the data and everything else can be ignored, so it is important to catch that feature in the display when applicable.

Vving also has three types of alarms built into it so if your Internet connection crosses the alarm thresholds Vving will beep at you until the situation is corrected.

Vving interleaves real-time data display with an interactive user interface. A user can resize the Vving window while Vving continues to collect data. Vving is multithreaded and has dynamic algorithms to account for many user-oriented actions so that the underlying Vving code scales to large size problems under multi-variant use conditions. That all means that the end user is given plenty of features without compromise. Some similar type systems constrain the user interface in one way or another because the underlying code was not designed to handle those user interface features. Not so with Vving. We have worked hard to ensure the robustness and scalability of its main function in conjunction with a good user experience.

The underlying software implementation is based on our Vvidget Pro programming frameworks and has many options not brought out in Vving. For instance, the implementation can format any amount of axis, although 6 y-axes is a practical limit whereas Vving only has two y axes.

Vving is amazing to watch and gives immediate results.
