Abstract: Example implementations relate to construction of a network service chain. For example, a system for construction of a network service chain can include a detection engine to detect a portion of a first network policy directing a subset of packets to a first service and a portion of a second network policy directing the subset of packets to a second service, and a construction engine to construct a network service chain of the first service and the second service in an order determined from a priority assigned to the first network policy and a priority assigned to the second network policy.

Abstract: Embodiments herein relate to transmitting specific traffic along a blocked link. A status of links between switches of a network is monitored. The status of the links is one of blocked and non-blocked. A blocked link is not used by a Spanning Tree Protocol (STP). At least one of the network switches is configured to transmit the specific traffic along the blocked link.

Abstract: In an example, a re-convergence point is determined for a convergence point in a network. A host is currently connected to the convergence point for example to access the network. Authentication information and a policy for the host is sent to the re-convergence point prior to the host connecting to the re-convergence point to access the network.

Abstract: Example implementations relate to network policy distribution. For example, a system for network policy distribution can include a state engine to determine a change in a state of a network, a policy engine to determine a number of policy changes based on the change in the state of the network, an identification engine to identify a number of network endpoints that correspond to the number of policy changes, and a distribution engine to load instructions based on the number of policy changes to the number of endpoints that correspond to the number of policy changes.

Abstract: Example implementations relate to compiling network policies. In an example, a method includes dividing a plurality of network policies into an exclusive policy group and a non-exclusive policy group, compiling the policies in the exclusive policy group into a first plurality of orthogonal policies, compiling the policies in the non-exclusive policy group into at least a second plurality of orthogonal policies, where the compiling of each policy group occurs separately.

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.
