Include Simulation Events for all Periods: In the Peak Link Utilization report, information is provided regarding the event triggering the peak link utilization, indicating which failure type triggered the peak link simulation (for example, node, link, or facility) and the name of the element. With this option unchecked, the simulation event is reported only for the planned period (based on the demand file) and worst failure scenario among the periods of the trafficload file. If this option is checked, the simulation event is also displayed for all of the individual periods (up to 24).
Generate Demand Over Tunnel Utilization Report: This option will generate the Demand Traffic on Tunnel report in the Tunnel layer reports.
Generate Peak Group Transit Statistics: Records the maximum number and bandwidth of demands transiting through a topology group. This information is displayed in the Group > Group Demand Bandwidth Distribution report of the Report Manager. These statistics can also be turned on by first setting CheckTransitDemandLimit=2 in the dparam file before opening the specification file.
Generate SRLG and Up-Down Sequence for Upper Layer: Selecting this option will generate a report, UPDOWN.runcode, which lists the demands or tunnels that went down during the simulation. This report is often used as an Up-Down Sequence File in an upper layer network in which the demands of the lower layer network are translated into links in the upper layer network. Thus, the demands that are reported as being down in the UPDOWN.runcode report can be read in as downed links in a custom failure simulation script for an upper layer network. Additionally, an SRLG file is created, based on the set of demands of the lower layer (links of the upper layer) which go down together.
Generate Detailed Reroute Information: Report detailed information on demands that rerouted during the failure simulation.
