Add a Container Normalization Task

Add a container normalization task for periodic container label-switched path (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 the + (Add) icon.

    The Add Task page (wizard) appears.

    Note:

    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.

    Note:

    Fields marked with an asterisk (*) are mandatory.

  4. After you complete each step in the wizard, click Finish.

    A confirmation message appears on top of the page, indicating that the task was added successfully. The details of this task are displayed on the Task Scheduler page.

Field

Description

Add New Task

Task Name

Specify a unique name for the task. The name can contain only alphanumeric characters and some special characters (greater than (<), less than (<), colon (:), underscore (_), and hyphen (-)).

Task Group

From the list, select Bandwidth Management Tasks.

Task Type

From the list, select Container Normalization.

Aggregation Statistic

From the list, select an aggregation statistic option.

The aggregation statistic works together with the task execution recurrence interval (the period of bandwidth adjustment) that you specify in the Schedule step in this wizard. 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. The available options are:

  • 80th, 90th, 95th, 99th Percentile (X percentile)—Aggregation is based on the selected percentile. The ‘X’ percentile is the value at which ‘X’ percent of all the samples taken in the previous sampling period lie at or below the calculated value.

  • 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.

Schedule

Startup Options

Schedule—Select Activate Later for the task to start at a specific date and time.

In the field that appears, click the calendar icon to select the date and time at which you want the task to start. Then, click OK.

For the task to start at the current date and time, click Now at the bottom of the calendar.

Note:
  • You can 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.

  • Container LSPs for which traffic statistics are not available for a specified duration will not be normalized if the container normalization task is scheduled to consider the statistics collected in the specified duration. This is because the task cannot differentiate between no traffic and zero bandwidth traffic.

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

  • Every—Specify the periodicity of the recurrence.

  • Ends—Select one of the following options:

    • Never—To configure the task to recur at the specified interval.
    • On—To select a date and time at which you want the task to end. In the field that appears, click the calendar icon and select the date and time. Then, click OK.
    • Now—To end a task at the current date and time, click Now at the bottom of the calendar.
