Temporarily stopping and starting VNFs and VDUs

Expand all | Collapse all

You can pause or suspend the VNF/VDU to free up system resources, such as CPU and memory, and make them available to other, higher-priority components. This may be necessary when user activity temporary decreases and new network functions must be provided. This management approach conserves resources and ensures efficiency.

The difference between a paused and a suspended VNF/VDU is that when the VNF/VDU is in suspended, its configuration information is saved on the disk of the VNF/VDU. This allows completely shutting down VNF/VDU and moving it to another host machine. When the VNF/VDU is reactivated, its configuration is completely restored.

To temporarily stop a VNF/VDU, use the following instructions:

• Pausing or suspending a VNF.

  To pause or suspend a VNF:

  1. In the menu, go to the Catalog section.

     The network service management page is displayed.

  2. In the Network services panel, select a network service.

     The graphical design tool with the network service topology is displayed.

  3. Click the VNF.

     The settings area is displayed in the lower part of the page. You can expand the settings area to fill the entire page by clicking the expand button .

     By default, the Flavours tab is selected, which displays the flavours of virtual machines for the network function. Flavours are described in the VNF package.

  4. In the upper part of the settings area, click Management and in the drop-down list, select Pause VNF or Suspend VNF.
  5. In the confirmation window, click Apply.

  The VNF is paused or suspended.
