Abstract: Example implementations relate to network policy conflict detection and resolution. For example, a system for network policy conflict detection and resolution can include a policy compilation engine to compile a plurality of network policies based on an intent format, a conflict detection engine to detect a conflict between a first network policy among the plurality of network policies and a second network policy among the plurality of network policies, using the intent format, and a conflict resolution engine to resolve the detected conflict between the first network policy and the second network policy. Further, the system for network policy conflict detection and resolution can include a translation engine to translate the resolution of the detected conflict to a protocol-specific format.

Abstract: Systems, methods, and storage mediums for determining a network cloud containing an uncontrolled network device based on link data of controlled network devices. The link data of controlled network devices can indicate which controlled network devices are linked together, whether the links between controlled network devices are multi-hop links, and whether the links between controlled network devices are bi-directional.

Abstract: In an example, a computer-readable medium may store executable instructions. The executable instructions may be to detect an inoperative network device in a communication network managed by a controller, determine a network switching function assigned to the inoperative network device, and provide the network switching function through the controller itself instead of the inoperative network device.

Abstract: Example implementations relate to generating a packet processing pipeline definition. According to an example, an SDN controller includes a flow class module to receive flow class registrations specifying flow classes. The flow classes specify characteristics of expected network flows. The controller also includes a pipeline generating module to generate a packet processing pipeline definition to accommodate the expected network flows, the packet processing pipeline definition including table definitions for the flow classes. The SDN controller further includes a communication interface to send the packet processing pipeline definition to a switch.

Abstract: Example embodiments disclosed herein relate to monitoring Dynamic Device Configuration Protocol offers via a control plane. In one example, an address range or multiple address ranges for sources of the Dynamic Device Configuration Protocol offers can be tracked. In this example, an anomaly can be determined based on one of the Dynamic Device Configuration Protocol offers and the address range(s).
