Service Chaining in Contrail SD-WAN

 

As of CSO Release 4.0, service chaining is available for SD-WAN environments. Service chaining is a concept wherein multiple network services instantiated in software and running on x86 hardware are linked, or chained together in an end-to-end fashion. This allows the one physical device to provide the services normally provided by multiple devices. Service chaining can be performed on NFX Series devices, as shown in Figure 1.

In CSO release 4.0, the following third-party virtual network functions (VNFs) are supported: Fortigate-VM and Single-legged Ubuntu VM.

Note

Currently only Layer 2 VNF mode is supported in SD-WAN service chains.

For CSO, you build service chains using the Designer Tools. Designer Tools are only available with the on-premise versions of CSO.
