Utilization Legends > Planned Node Load and Measured Node Load
The Planned Node Load pane allows you to view the planned load on each node based on the bandwidth of demands originating (Out), terminating (In) or passing through each node (Transit).
The Measured Node Load pane allows you to view the measured load of traffic going in or out of the network. This option shows traffic derived from measurements at the incoming and outgoing interfaces. To use this feature, you should indicate in the specification file the location of the following files that specify the traffic going in/out of the node from interfaces: interfaceLoad_in (ingress), interfaceLoad_out (egress). See the NorthStar Planner Feature Guide for more details.
For the Planned Node Load and Measured Node Load panes, there is a color legend that colors the nodes according to the node load. The colors and divider locations can be modified in this legend.
In addition, the Node Load legend draws each node as a circle. The bigger the traffic going in/out of the node, the bigger the circle is, so you can easily see which nodes have the most traffic to the outside world. For Measured Node Load, there is also a slider to choose one of up to 24 periods to display.
For MPLS-enabled networks, you will see a different view depending upon whether Layer 2 or Layer 3 is selected from the top menu bar of the main window. Selecting Layer 2 allows you to view the planned load of LSP Tunnels.
