Network Monitoring Demo

This demo shows a simple network monitoring tool. You can watch the traffic flow through the network and even influence the network. The network consists of PCs, Laptops, Tablets, Switches, Servers, Databases and W-LANS. The color of the edges change from green to yellow to red depending on its traffic load. The traffic load of nodes is shown on their info label. Active edges are marked through an animation.

Things to try

Open/Hide Info Label: Every node has an info label. It can be shown and hidden by clicking on the node. It shows the name, IP address and traffic load. You can also close it by clicking on the x in the top right corner. Remember that info labels are only visible at a detailed zoom level.
Disable nodes: The info label also contains a power button in the bottom right corner. Clicking on it (de)activates the node, preventing it from processing data. This way you can influence the data flow and watch what happens.
Enable Failures: By Clicking on "Enable Failures" you allow failures to happen randomly. Nodes and edges get broken and can't process data anymore. Broken elements are marked with a stop sign. If a failure happens on a node or edge outside the current viewport, then the viewport will be moved to focus the broken element. You can repair elements by clicking on the stop sign. To repair a node, you can also open the info label and then click on the green arc arrow at the bottom right corner.

Class	Description
demo.view.networkmonitoring.NetworkMonitoringDemo	Allows to watch and influence the traffic flow through a network.
demo.view.networkmonitoring.NetworkData	Network data for a network node or a connection as seen by the view.
demo.view.networkmonitoring.NetworkInfoLabelPainter	Paints an info label that displays a label text and additional buttons on a bubble shaped background.
demo.view.networkmonitoring.NetworkConnectionPainter	A painter that paints network connections.
demo.view.networkmonitoring.NetworkInteractionMode	ViewMode to disable, enable or repair network nodes and edges.
demo.view.networkmonitoring.NetworkModel	Interface for a network model
demo.view.networkmonitoring.NetworkModelImpl	This is an elementary network model that creates consistent data load. In this model, PCs generate data. Data is sent between nodes without a specific target. The nodes behave differently: Switches and W-LANs route data to the least busy node. Server and databases send (maybe more) data back to the node who send him data. PCs, Laptops and Tablets generate data and are the only target for data
demo.view.networkmonitoring.NetworkModelObserver	Interface for NetworkModel observer
demo.view.networkmonitoring.NetworkMonitoringFactory	Factory class that provides realizer configurations for network nodes and connections. Also provides color constants and the warning icon.
demo.view.networkmonitoring.NetworkNodeInfo	Contains the name and ip address of a network node
demo.view.networkmonitoring.NetworkNodePainter	A painter that paints a network node either in enabled or disabled state.
demo.view.networkmonitoring.NetworkView	The network view creates a view graph and updates it every time the state of elements in the model graph changes.

Running the Demos

From Within an IDE

Set <yFilesDir>/src as your source directory. Then add <yFilesDir>/lib/y.jar and the source folder <yFilesDir>/src to your classpath. Now you should be ready to compile and run all executable demo classes.

With Ant

First make sure you have the build tool Ant installed on your system. Now you can use the demo build script build.xml located in <yFilesDir>/src/demo to launch each demo by specifying its simple class name as a target. Alternatively, launch the interactive demo driver by specifying run as target to conveniently access all demos.
