Adding Egress Throttle Groups

Use this task to create new Egress Throttle Groups.

Egress Throttle Groups fields are described in Egress Throttle Groups elements.

  1. Select Diameter > Configuration > Egress Throttle Groups.

    The Diameter > Configuration > Egress Throttle Groups page appears.

  2. Click Insert.

    The Diameter > Configuration > Egress Throttle Groups [Insert] page appears.

  3. Enter a unique name for the Egress Throttle Group in the Egress Throttle Group Name field.
  4. Select one or both of the throttling choices for this Egress Throttle Group by checking one or both boxes in the Egress Throttlings field. One or both boxes must be selected for all Egress Throttling Groups.
    • Under the Members tab, enter values for the following fields:
    1. Peers

      Use the pulldown list to select from a list of Peer names, clicking the Add button after each selection. Use the X to the right of the pulldown list to remove a selection.

    2. Connections

      Use the pulldown list to select from a list of Connection names, clicking the Add button after each selection. Use the X to the right of the pulldown list to remove a selection.

    • If the Rate Limiting check box for Egress Throttlings is checked for this Egress Throttle Group, enter values for the required fields and for optional fields, as needed. To control the total egress Request traffic rate that a DSR will route to a user-defined group of Connections or Peers associated with this Egress Throttle Group, select the Rate Limiting tab, and enter values for the following fields:
    1. Maximum Egress Request Rate

      Enter the maximum allowed Egress Request Rate shared by associated members.

    2. Onset Threshold Level (1%).

      Enter the Onset Threshold Level 1.

    3. Abatement Threshold Level (1%).

      Enter the Abatement Threshold Level 1.

    4. Onset Threshold Level (2%).

      Enter the Onset Threshold Level 2.

    5. Abatement Threshold Level (2%).

      Enter the Abatement Threshold Level 2.

    • If the Pending Transactions Limiting check box for Egress Throttlings is checked for this Egress Throttle Group, enter values for the required fields and for optional fields, as needed. To control the total number of transactions that a DSR will allow to be pending for a user-defined group of Connections or Peers associated with this Egress Throttle Group, select the Pending Transaction Limiting tab, and enter values for the following fields:
    1. Maximum Egress Pending Transactions

      Enter the maximum allowed Egress Request Rate shared by associated members.

    2. Onset Threshold Level (%1%).

      Enter the Onset Threshold Level 1.

    3. Abatement Threshold Level (1%).

      Enter the Abatement Threshold Level 1.

    4. Onset Threshold Level (2%).

      Enter the Onset Threshold Level 2.

    5. Abatement Threshold Level (2%).

      Enter the Abatement Threshold Level 2.

    6. Onset Threshold Level (3%).

      Enter the Onset Threshold Level 3.

    7. Abatement Threshold Level (3%).

      Enter the Abatement Threshold Level 3.

    8. Abatement Time (msec)

      Enter the amount of time Egress Pending Transactions must remain below an abatement threshold before the congestion level is lowered.

  5. Click:
    • OK to save the changes and return to the Diameter > Configuration > Egress Throttle Groups page.
    • Apply to save the changes and remain on this page.
    • Cancel to return to the Diameter > Configuration > Egress Throttle Groups page without saving any changes.

    If OK or Apply is clicked and any of the following conditions exist, an error message appears:
    • The maximum number of Egress Throttle Groups have already been created.
    • There is no Peer Node or Connection in the signaling network element corresponding to the Egress Throttle Group to be added.
    • Any required fields are left empty.
    • An Egress Throttle Group is configured with the greater than the maximum total number of Peers and Connections.
    • An Egress Throttle Group is configured with duplicate Peers or Connections.
    • An Egress Throttle Group is configured with thresholds at level 3 set but thresholds at level 2 are missing.
    • An Egress Throttle Group is configured with Onset Thresholds at a congestion level 2 or level 3 without providing corresponding Abatement Thresholds.
    • An Egress Throttle Group is configured with Abatement Thresholds at a congestion level 2 or level 3 without providing corresponding Onset Thresholds.
    • An Egress Throttle Group is configured with Onset Threshold at a congestion level lesser than the corresponding Abatement Threshold level at the same level.
    • An Egress Throttle Group is configured with Onset Threshold at a congestion level greater than the corresponding Abatement Threshold at the succeeding level
    • An Egress Throttle Group is configured with a Peer already configured as a member in any Egress Throttle Group. (Explicit association of Peer with another Egress Throttle Group)
    • An Egress Throttle Group is configured with a Peer which is associated with a Connection configured as a member in any Egress Throttle Group. (Implicit association of Peer with another Egress Throttle Group)
    • An Egress Throttle Group is configured with a Connection already configured as a member in any Egress Throttle Group. (Explicit association of Connection with another Egress Throttle Group)
    • An Egress Throttle Group is configured with a Connection which is associated with a Peer configured as a member in any Egress Throttle Group. (Implicit association of Connection with another Egress Throttle Group)
    • An Egress Throttle Group is configured with a Connection and a Peer associated with each other.
