Web Planner Interactive Simulation

 

Interactive simulation enables you to specify the nodes, links, and facilities for which you want to run a failure simulation, and see how the network would be impacted by viewing the respective topology changes and generated reports.

Note

This is different from exhaustive failure simulation which is a Design Mode tool. You cannot use the exhaustive failure simulation tool while in Simulation Mode. Simulation Mode is specifically for interactive simulation. For more information about the exhaustive failure simulation tool, see Simulation.

To run an interactive simulation:

  1. Open a network or a session.
  2. Select Simulation from the drop-down menu of the top menu bar to enter the Simulation Mode.

    Figure 1 shows this selection.

Simulation Mode

    In the Simulation Mode, the network information table at the bottom displays Fail Nodes, Fail Links, and Fail SRLGs/Facilities.

    Note

    In the simulation mode, the Simulation tab (Exhaustive simulation) on the left main menu is disabled. Also, actions on the top right menu bar like Network, Select Layer, and Update Network are also disabled.

  3. Select one or more nodes, links, or facilities from the network information table on which you want to run a failure simulation.

    The selections you made are highlighted on the topology map with a red “F” indicating failure.

  4. Click Run at the bottom of the network information table.

    Interactive simulation is run based on the selected nodes, links or facilities. A red lock icon appears on the top-right corner of the window to indicate that the server is busy and simulation is in progress.

    Note

    You can click on Reset Simulation to reset the network to a state before this simulation was run.

    Once the simulation is complete, you can click the add (+) icon on the network information table to view the generated link changes, demand changes, and tunnel changes reports.

    In the link changes tab, you can view the detailed information on link bandwidth and utilization changes.

    In the demand changes and tunnel changes tab, you can view new path and old path related information such as changes in hops, delay, or bandwidth. If you select any row on the demand changes tab, you can view the new path in blue color, old path in yellow color, and shared links between these two paths in green color on the topology map.

    You can also click on the download button to download any of these reports in a CSV format.
