Abstract: A virtual port group abstraction can facilitate automated configuration of devices in a data center. For example, a data center administrator can define a virtual port group to include a set of logical and physical interfaces for devices allocated to a particular department or other group within a company. An administrator for the department can then utilize a user interface to perform actions with respect to the virtual port group. The actions can include configuration actions, modeling actions and/or deployment actions. An action received by a network management controller such as a Software-Defined Networking (SDN) controller can be converted into the appropriate actions for the relevant logical and physical interfaces that are configured to be part of the virtual port group.

Abstract: A system for configuring a data center includes a fabric management server coupled to a management switch. A provisional Software Defined Networking (SDN) controller executing on the fabric management server can discover physical servers coupled to the management switch, receive network interface configuration information from the physical servers, and use the discovered network interface configuration information to determine a configuration for switches and servers coupled to an IP fabric. The configuration can be migrated to a full functionality SDN controller.

Abstract: An example controller device that manages a plurality of network devices includes one or more processing units implemented in circuitry and configured to receive, via an application programming interface (API) framework, an indication of an intent. The intent includes data indicating an update to a data structure including a plurality of nodes representing the plurality of network devices and a plurality of edges connecting the plurality of nodes. The one or more processing units are further configured to process the intent to select a topology compiler from a plurality of topology compilers and invoke, via the API framework, the selected topology compiler using a role of a network device of the plurality of network devices and an indication of the network device as input to generate abstract configuration information. The one or more processing units are further configured to configure the network device based on the abstract configuration information.

Abstract: An access profile includes configuration characteristics that are defined using device and operating system agnostic attributes. Thus, the access profiles are not necessarily dependent or otherwise tied to any particular vendor or network OS. When a system administrator configures one or more service access points, the system administrator need only specify the vendor and network OS agnostic characteristics that are to be associated with the service access point. A configuration generator can generate vendor specific and/or network specific configuration commands and data from the vendor and network OS agnostic access profile attributes. The generated configuration commands and data can be provided to a network device hosting the service access point using a vendor specific and/or network OS specific configuration application program interface.

Abstract: In an example, a method includes processing, by an application programming interface (API) server implemented by a configuration node of a network controller for a software-defined networking (SDN) architecture system, requests for operations on native resources of a container orchestration system; processing, by a custom API server implemented by the configuration node, requests for operations on custom resources for SDN architecture configuration, wherein each of the custom resources for SDN architecture configuration corresponds to a type of configuration object in the SDN architecture system; detecting, by a control node of the network controller, an event on an instance of a first custom resource of the custom resources; and by the control node, in response to detecting the event on the instance of the first custom resource, obtaining configuration data for the instance of the first custom resource and configuring a corresponding instance of a configuration object in the SDN architecture.

Abstract: Techniques are disclosed for providing a Software Defined Networking (SDN) controller with real-time or near-real time visibility of the operation of data center fabrics to determine whether the DCI was properly configured. For example, an SDN controller receives high-level configuration data that describes a desired state of a network managed by the SDN controller at a high level of abstraction. The SDN controller applies a transformation function to the high-level configuration data to generate a low-level configuration data for network devices configured to implement the desired state of the network. SDN controller configures the SDN controller as a peer to the network devices to obtain one or more routes exchanged between the network devices. The SDN controller sends the low-level configuration data to the network devices to cause the network devices to implement the desired state of the network.
