Designing Network Services

Designing a Network Service for a Centralized Deployment

Procedure

1. Click Home in the toolbar and Requests in the left navigation bar.

   The Requests page appears, displaying the open requests.

2. Click Begin.

   The Build page displays the requested network functions and the goals.

3. Click the first function in the chain.

   The VNF catalog at the bottom right of the page is refreshed to show the VNFs that provide this function.

4. Drag and drop a VNF from the catalog to the Network Service Design workspace.

   The function appears inside the VNF image.

5. Add an ingress point to the first VNF in the chain.

   The Performance Goals pane is refreshed to indicate how the network service design meets the defined goals.

6. Click the next function in the chain.

   The VNF catalog is refreshed to show only the VNFs that provide this function. If a VNF in the Network Service Design workspace supports this function, a faded image of the function appears inside the VNF image.

7. Choose a VNF for this function:

   • To implement this function with the same VNF, click the faded image in the VNF image.

   • To implement this function with a different VNF, drag the VNF from the Vendor catalog to the Network Service Design workspace.

8. Repeat Step 6 and Step 7 until you have assigned a VNF to each required network function. If you make an error in the design area, you can right-click and delete the component.
9. If you have used multiple VNFs in your design, connect them by packet flow.
10. Add an egress point to the last VNF in the chain.

    The Performance Goals pane is refreshed again to indicate how the network service design meets the customer goals.

11. Click Save NSD to save the design.
12. (Optional) Configure the Network Service.
13. Click Publish NSD to add the service to the catalog.

    The Publish NSD page appears.

    1. Specify a name (that customers see) for this network service.

       The field accepts up to 60 characters, including letters, numbers, and symbols.

    2. Specify a description of the service.

       The field accepts up to 500 characters, including letters, numbers, and symbols.

    3. Select the type of service from the menu.

    4. Click Publish.

Designing a Network Service for a Distributed Deployment

Procedure

1. Click Home in the toolbar and Requests in the left navigation bar.

   The Requests page appears, displaying the open requests.

2. Click Begin.

   The Build page displays the requested network functions and the goals.

3. Click the first function in the chain.

   The Vendor catalog is refreshed to show only the VNFs that provide this function.

4. Drag the VNF from the Vendor catalog and drop the network functions at the appropriate points in the network chain to meet the requirements of your network.

   The Performance Goals pane is refreshed to indicate how the network service design meets the customer goals.

   Note The ingress point, egress points, and gateway router are automatically updated for the distributed deployment model.

5. Click the next function in the chain.

   The Vendor catalog updates to show only the VNFs that provide this function. If a VNF in the Network Service Design workspace supports this function, a faded image of the function appears inside the VNF image.

6. If you have used multiple VNFs in your design, then drag and drop the network functions at the appropriate points in the network chain.

   The Performance Goals pane again updates to indicate how the network service design meets the customer goals.

7. Repeat Step 4 and Step 5 until you have assigned a VNF to the required network function. If you make an error, you can right-click a component in the network service design area and delete the component.
8. (Optional) Click Function Configuration and configure the network service.
9. Click Save NSD to save the design.
10. Click Publish NSD to add the service to the catalog.

    The Publish NSD page appears.

    1. Specify an official name (that customers see) for this network service.

       The field accepts up to 60 characters, including letters, numbers, and symbols.

    2. Specify a description of the service for customers to read.

       The field accepts up to 500 characters, including letters, numbers, and symbols.

    3. Select the type of service from the menu.

    4. Click Publish.
