Node View

This is a main part of the NetLimiter. Here you can set or release speed limits for applications, their instances and connections. Node View architecture is based on enhanced tree view and should be familiar to all Windows users.



Nodes

Node view displays tree of nodes. The first level of the node tree represents all applications that are connected to the internet. Applications are identified by executable file which was used to run them. When you click on a node for given application, then youÆll get a list of all its running instances (unrolled below). Instances are identified by their system process ID, but as display name is used the name of their main window if they had created any. If the given instance doesnÆt create windows (for ex.: console applications) or it is impossible to query them, then the instanceÆs process ID (PID) is used as a display name.

If you expand node for given instance then youÆll get a list of all created connections. The connections are strictly identified by the IP address number of a remote computer. The IP is used as a display name for the connection.
Note, that every computer connected to the internet is identified by its IP address (even yours). Any application can establish connection to any computer on the internet as many times as it needs or remote computer allows.
At every application, instance or connection you can find four columns. Where first (from left to right) column shows current download rate for a node (in kilobytes per second), second letÆs you set download rate limit, third shows upload rate and four letÆs you set download rate limit (in kilobytes per second).

Top Node

Beside these three types of nodes, there is one node which is a little bit different. It is Top Node with name ôOverallö. It is always on the top of the Node window (has a black background). It only displays total download and upload rates for all applications running on the computer. If you set limit on the Top node, then it has impact on all running applications, ignoring their own limits - be careful using this feature.

There are also three pages in the Node view. First of them named ôOnlineö contains only applications, which are currently connected or are trying to connect to the internet . The ôOfflineö page works as a storage for applications, which were connected to the internet in the past, but now are not connected or doesnÆt even run. Third page ôHiddenö is a depository for applications you donÆt want to bother with. If you don't care what any app does and you want to have "Online" clean, put such app into "Hidden" tab. To move any application into ôHiddenö tab, click on its node (on Online or Offline page) with right mouse button and in context menu select command ôMove To Hiddenö.

Setting the Limits

To set download/upload limit for any node you have to select it first by clicking on it. Then repeatedly click on small buttons with arrows in download/upload rate column to increase or decrease limit in 1 kB/s steps. You can also click with left mouse button in space between these two buttons and hold it while moving mouse cursor up or down. The maximum limit values can be set directly on the Property page which is on the left from Node view.
In the new versions of Netlimiter (since 1.20) you can enter limits directly from keyboard. Select the node, click on the frame with limit value and enter new limit into edit box. Push "Enter" to confirm the limit or "Esc" to dismiss the limit.
If you want to enable the limit, you have to check the check button (grey rectangle) on the left side of the column. If you want to disable the limit, simply uncheck the check button.
