Exhaustive Failure Simulation

Use Routing Director to simulate a failure scenario in your network model. A report is generated after you run the simulation. Check the reports to understand the impact of various failures to the network.

To create a failure scenario:

  1. Navigate to Planning > Networks > Offline Models.
    The Working Models page is displayed.
  2. From the list of network models (offline version of a live network), select a network model on which you want to simulate a failure scenario.
  3. Click the Simulation button to define a failure scenario that you want to apply to simulate in your network model. The Exhaustive Failure Simulation page is displayed.
    Note:

    Before you run a simulation, ensure that you save the changes made to the network model by clicking More > Save Model.
  4. Complete the configuration according to the guidelines in Table 1.
    Note: Fields marked with an asterisk (*) are mandatory.
  5. Click Simulate to create a failure scenario.

    A message indicating that the simulation is complete is displayed. Depending on the size of the network the simulation task might take longer to complete, despite the message indicating completion of the simulation. Reports are generated only after the simulation is complete.

  6. On the Reports page (Working Models > select the model > click Reports), check the reports to understand how your network reacted to the failure scenario. For more information, see View Reports.

Table 1: Fields on the Exhaustive Failure Simulation Page
Field Description
Layer*

Select the layer for which you want to create the failure scenario. You can choose one of the following:

  • Demand (Layer 3)

  • Tunnel (Layer 2)
Description Describe the failure scenario that you are creating.
Exhaustive Failure*

Select the type of failure (single) you want to simulate.

Currently, you can simulate and check how the network is affected when one of the links or nodes in the network fails at a time.

For example, if a network has 10 links, at any point in time, Routing Director fails only one link and simulates how the network would react to the failure scenario. The same is applicable for the node failure.

Failure Type* Select the failure type. You can simulate failure scenarios for links and nodes.
