Designing and Publishing Network Services


This section is only relevant for on-premises deployments of Contrail Service Orchestration (CSO).

The CSO Designer Tools consist of three tools that you use to create VNF templates, packages, and service chains that can be deployed as network services for the CSO solutions. CSO Designer Tools are not available for cloud-hosted deployments of CSO. You access the CSO Designer Tools at the same URL as the CSO Administration Portal, but on port 83. For example, if the IP address of the Administration Portal is, then the URL for Designer Tools would be: Figure 1 shows an overview of the workflow used within the Designer Tools application.

  • First, you use the Configuration Designer to create configuration templates for virtualized network functions (VNFs). The configuration templates specify the parameters that the customer can configure for a network service.

  • Then, you use the Resource Designer to create VNF packages. A VNF package is based on a VNF template and specifies the network functions, function chains, and performance of the package.

  • Finally, you use the Network Service Designer to:

    • Design service chains for network services using the VNF packages that you created with the Resource Designer.

    • Configure the network services.

    • Publish network services to the network service catalog.

You use the same process to create network services for Hybrid WAN, and SD-WAN deployments. The same network service can not be shared between an on-premises site and the service provider’s POP.


Currently, SD-WAN deployments support only Layer 2 (L2) service chains while Hybrid WAN deployments can support L2 and L3 service chains.
