Creating a network service

You can create a network service manually or using a template. When you use a template to create a network service, the topology of the service is built in accordance of the topology of the template, and you can then modify it by adding or removing components.

To create a network service:

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

   The network service management page is displayed.

2. In the Network services panel, click + Network service.

   The graphical design tool for building the network service topology is displayed.

3. If you want to use a template to create the network service, drag the template from the Catalog pane to the graphic designer.

   The topology is constructed in accordance with that template.

4. Drag the following network components from the Catalog pane to the graphical design tool to add them to the topology:
   • Virtual network functions.
   • Physical network functions.
   • Shared network services. If a shared network service is added to a topology of multiple network services, it can be used to interconnect those network services.

   When adding a network function, in the window that is displayed, select where you want to place it — in the data center or on the uCPE device.

   To remove an added network component, click it and select Delete from the drop-down list.

5. Drag the following links from the Links tab in the lower part of the screen to the graphical design tool to add the links to the topology:
   • P2P — P2P transport service
   • P2M — P2M transport service
   • M2M — M2M transport service

   The remaining links are relevant to network communication at the VIM level and are established between VNFs hosted by the OpenStack cloud platform:

   • OS shared — a network that can be shared by multiple tenants
   • OS vRouter — a router that provides L3 routing
   • OS VLAN — a network for transmitting tagged L2 traffic of the 802.1Q standard
   • OS VXLAN — a network that provides VXLAN tunneling
   • OS flat — a network for transmitting untagged L2 traffic

   When adding a OS VLAN, OS VXLAN, or OS flat connection, in the window that is displayed, select where you want to place it — in the data center or on the uCPE device.

   To remove an added link click it and select Delete from the drop-down list.

6. In the lower part of the page, select the UNI tab and drag UNI and/or WAN interfaces to the graphical design tool to add them to the topology. To remove an added interface, click it and select Delete from the drop-down list.
7. Configure topology components.
8. Connect the links to the network components:
   1. Click a link and in the drop-down list, select Add leaf to connect a network component that has the Leaf role. If you clicked a P2M service, you can select Add root in the drop-down list to connect a network component that has the Root role.
   2. Click the network component icon and in the displayed window, select an interface for the connection.

   The link is connected to the network component, which is indicated in the topology by a line between them. For example, the figure below shows a VLAN connected to a VNF.

   

9. Connect the links to interfaces:
   1. Click a link and in the drop-down list, select Add leaf to connect an interface that has the Leaf role. If you clicked a P2M service, you can select Add root in the drop-down list to connect an interface that has the Root role.
   2. Click the intefrace icon.

   The link is connected to the interface, which is indicated in the topology by a line between them. For example, the figure below shows a P2P service connected to a UNI and WAN interface.

   

10. If necessary, assign backup interfaces to the UNI:
    1. Click the UNI and in the drop-down list, select Reserve.

       A backup interface can be assigned only for UNIs to which at least one link is connected.

    2. Click the icon of the interface that you want to use as a reserve interface.

    The interface is designated as the backup interface for the UNI, and a dotted line is displayed between the UNI, the backup interface, and the link connected to the UNI. For example, in the figure below, the WAN interface is the backup interface for the UNI.

    

11. If necessary, do the following:
    • Select the Description check box to display a description under each topology component. This check box is selected by default.
    • ClickArrange to align topology components vertically.
12. In the Name field, enter the name of the network service.
13. Complete the network service creation:
    • To save the network service, click Save.
    • To save and immediately deploy a network service, click Deploy.

The network service is created and displayed in Network services panel. If you clicked Deploy, the deployment of the network service begins, which may take several minutes. You can interrupt the deployment by clicking Abort deploy.
