Add a Container Normalization Task


Use the Task Scheduler page to add a container normalization task for periodic container LSP normalization.

The container normalization task computes aggregated bandwidth for each container LSP and sends it to the Path Computation Server (PCS). The PCS determines whether it needs to add or remove sub-LSPs belonging to the container LSP, based on the container’s new aggregated bandwidth.

To add a container normalization task:

  1. Select Administration > Task Scheduler.

    The Task Scheduler page appears.

  2. Click Add.

    The Create New Task page (wizard) appears.


    You can have only one container normalization task per Paragon Automation server. If you attempt to add a second, the system will prompt you to approve overwriting the first one.

  3. Configure the fields in each step of the wizard according to the guidelines provided in Table 1.

    Click Next to go to the next step.


    Fields marked with an asterisk (*) are mandatory.

  4. After you complete steps 1, 2, and 3 in the wizard, click Submit.

    The details of the task that you added are displayed on the Task Scheduler page.

    After the task is completed, select the task in the list to view the results in the Summary, Status, and History tabs.

Table 1: Fields on the Create New Task Wizard (Container Normalization)



Step 1


Specify a meaningful name for the task.

Task Group

From the list, select Bandwidth Management tasks.

Task Type

From the list, select Container Normalization.

Step 2

Aggregation Statistic

From the list, select an aggregation statistics option.

The aggregation statistic works together with the task execution recurrence interval (the period of bandwidth adjustment) that you specify in Step 3. The Path Computation Element (PCE) aggregates the LSP traffic for the interval based on the aggregation statistic you select, and uses that information to calculate the new aggregated bandwidth. Following are the available options:

  • 80th, 90th, 95th, 99th Percentile—Aggregation is based on the selected percentile.

  • Average—For each interval, the samples within that interval are averaged. If there are N samples for a particular interval, the result is the sum of all the sample values divided by N.

  • Max—For each interval, the maximum of the sample values within that interval is used.

Step 3


Note: You must schedule the task to repeat at a specific interval from a minimum of 15 minutes to a maximum of one day. The default interval is one hour.

Startup Options:

  • Starts On—Click the calendar icon to select the date and time at which the task starts. To start the task at the current date and time, click Current Date and Time at the bottom of the calendar.

  • Timezone—Displays the server timezone.

Recurrence Options:

  • Repeats—Specify the frequency (in Minutes, Hours, or Days) at which the task recurs.

  • Every—Specify the periodicity of recurrence.

  • Ends—Select Never if you want the task to recur at the specified interval automatically. Alternatively, select On, and click the calendar icon to specify a date and time at which you want the task to end. To end a task at the current date and time, click Current Date and Time at the bottom of the calendar.

  • Timezone—Displays the server timezone.
