Routable and intent-based service chains

A network controller comprising:

• one or more memories having computer-readable instructions stored therein;
• and
• one or more processors configured to execute the computer-readable instructions to:
• receive an intent-based description of one or more services to be applied to network traffic;
• applying a language processing model to the intent-based description to define a type for a service chain that includes an identification of the service chain, a virtual routing and forwarding identification of the service chain, and a respective identification of each of the one or more services based on the intent-based description;
• route the network traffic to and from the one or more service included in the service chain using the type as an address of the service chain;
• implement the service chain at one or more network hubs;
• and
• generate a traffic steering policy in the network for steering the network traffic to the one or more network hubs to be serviced by the one or more services;
• and
• send the traffic steering policy to one or more network routers for steering the network traffic (1) to the one or more network hubs;
• and (2) to one or more intended destination after the network traffic is serviced by the one or more services.

One or more non-transitory computer-readable media comprising computer-readable instructions, which when executed by one or more processors of a network controller, cause the network controller to:

• receive an intent-based description of one or more services to be applied to network traffic;
• apply a language processing model to the intent-based description to define a type for a service chain that includes an identification of the service chain, a virtual routing and forwarding identification of the service chain, and a respective identification of each of the one or more services based on the intent-based description;
• route the network traffic to and from the one or more service included in the service chain using the type as an address of the service chain;
• implement the service chain at one or more network hubs;
• generate a traffic steering policy in the network for steering the network traffic to the one or more network hubs to be serviced by the one or more services;
• and
• send the traffic steering policy to one or more network routers for steering the network traffic (1) to the one or more network hubs;
• and (2) to one or more intended destination after the network traffic is serviced by the one or more services.
