Abstract: An example method includes determining, by a network controller, based on a high-level data model, vendor-agnostic device information for a first network device, translating the vendor-agnostic device information into vendor-specific device information, sending, to the first network device, first configuration information included in the vendor-specific device information to cause the first network device to switch into a maintenance mode and enable diversion of network traffic from the first network device to a second network device, responsive to verifying that the first network device has diverted the traffic, initiating maintenance procedures on the first network device while the first network device is in the maintenance mode, and sending, to the first network device, second configuration information included in the vendor-specific device information to cause the first network device to switch out of the maintenance mode and enable reversion of network traffic from the second device to the first network device.

Abstract: Network controllers are described that enable creation of logical interconnects between logical routers of different, isolated virtual networks and for auto-generation and deployment of routing policies to control “leaking” of select routes amongst the different virtual networks. In one example, a network controller includes a memory and processing circuitry configured to identify a source logical router of a first virtual network and a destination logical router of a second virtual network implemented on one or more physical devices of a switch fabric, form a policy defining one or more rules for controlling leaking of one or more of the routes through a logical router interconnect from the source logical router to the destination logical router, and push the policy to the one or more physical devices of the switch fabric for application to communications through the logical router interconnect.

Abstract: In general, techniques are described for a creating a virtual network router within a software defined network (SDN) architecture. A network controller for the SDN architecture system may include processing circuitry that is configured to execute a configuration node and a control node. The configuration node may process a request by which to create a virtual network router (VNR), where the virtual network router may cause the network controller to interconnect a first virtual network (VN) and a second VN. The VNR may represent a logical abstraction of one or more policies that cause import and/or export of routing information between the first VN and the second VN. The control node configures the first VN and the second VN according to the one or more policies to enable the import and/or the export of routing information between the first VN and the second VN via the VNR.

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: In general, techniques are described for defining and executing device-independent commands on a network having a plurality of network devices. In some examples, a controller includes a graphical user interface. The controller displays, via the graphical user interface, network devices that support a device-independent command selected from one or more device-independent commands, wherein each device-independent command performs one or more operations on supported network devices. The controller receives, via the graphical user interface, user input selecting two or more of the displayed network devices and performs the one or more operations of the selected device-independent command on the selected network devices. In some examples, performing includes executing tasks associated with each network device, wherein the tasks, when executed, perform the one or more operations on each respective network device.

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.
