Planner offers extensive reporting capabilities for network planning and simulation. These reports help quickly assess and summarize network-related data and can be generated in the CSV (comma-separated) or text format.

After you run simulation on your network model, Routing Director generates a report. These reports are listed on the Reports page. (Planning > Networks > Offline Models > Model-Name > Reports).

On the Reports page, you can do the following:

  • View the list of reports generated for each simulation in the Simulation table. The Simulation table displays the following information (columns):

    • Report—Every time you run a simulation, a list of reports is generated. This column groups the reports simulation-wise. Click on each report to view detailed information about that report.

    • Description—Describes the report.

    • Created—Displays the date and time at which the report is generated.

    • Filename—Displays the filename of the report. Click the link to download the report.

    • Size—Size of the report.

  • View the details of each report— To view the details of exhaustive and what-if reports.

    • Click the Exhaustive down-arrow in the Simulation table under Reports. The following reports are generated for tunnels and demands:

      • Traffic on Links—This report is generated only for tunnels. Includes information on each link's peak utilization caused due to one or more failed elements. Click the Traffic on Links link to view a detailed report.

      • Link Utilization—This report is generated only for demands. Includes information on each link’s peak utilization caused due to one or more failed elements. Click the Link Utilization link to view a detailed report.

      • Oversubscribed Links—This report is generated for both tunnels and demands. Includes information on the links that have more than 100% utilization during exhaustive failure simulation. Click the Oversubscribed Links link to view a detailed report.

      • Failed Tunnel Path—This report is generated only for tunnels. Includes information on tunnels that were unable to reroute, and the events that prevented tunnel reroute during exhaustive failure simulation. Click the Failed Tunnel Path link to view a detailed report.

      • Failed Path—This report is generated only for demands. Includes information on demands that were unable to reroute, and the events that prevented reroute during exhaustive failure simulation. Click the Failed Path link to view a detailed report.

      • Simulation Summary—This report is generated for both tunnels and demands. Includes information on the summary of the count, bandwidth, and the number of hops of the tunnels or demands that were failed or were impacted during exhaustion simulation. Click the Simulation Summary link to view a detailed report.

      • Traffic on Physical Links—This report is generated only for tunnels. Includes information on physical interfaces with normal utilization and with the worst utilization, and the events that caused the peak utilization during exhaustive failure simulation. Click the Traffic on Physical Links link to view a detailed report.

      • Physical Link Utilization—This report is generated only for demands. Includes information on physical interfaces with normal utilization and with the worst utilization, and the events that caused the peak utilization during exhaustive failure simulation. Click the Physical Link Utilization link to view a detailed report.

    • Click the What-if down-arrow in the Simulation table under Reports. The following reports are generated :

      • Demand Change—Includes information on demands that were impacted by the failure, and the old and new path information for each of those demands.

      • Link Change—Includes information on links that were affected by the failure, which includes the links which went down due to failure and links whose bandwidth utilization changed as a result of rerouting of tunnels and demands through them.

      • Tunnel Change—Includes information on tunnels that were impacted by the failure, the original path and new path for each tunnel.

    For information on each field in a report, see Table 1 and Table 2.

  • Download reports—You can download reports in the following ways:

    • On the Simulation table, click the link in the Filename column. The report is downloaded to your local system.

    • On the Simulation table, click the Exhaustive down-arrow > Report-Name (link). You are directed to the page that displays information on the specific report. Click the Download option. The report is downloaded to your local system.

    For information on each field in a report, see Table 1 and Table 2.
