Abstract: A computer-implemented method for aggregating and exposing infrastructure capability information is provided. The method includes extracting infrastructure capability information, wherein the infrastructure capability information includes available resource types and, for each available resource type, first attribute information including a first attribute name and a first attribute value. The method further includes, for each available resource type: determining whether the first attribute value is a literal type attribute value or a numerical type attribute value; for an attribute value determined to be the literal type, aggregating the first attribute information to generate aggregated literal attributes information; and for an attribute value determined to be the numerical type, aggregating the first attribute information to generate aggregated numerical attributes information. The method further includes receiving a request for a resource including requested resource types and, for each requested resource type, second attribute information including a second attribute name and a second attribute value. The method further includes, for each requested resource type: determining whether the second attribute value is a literal type attribute value or a numerical type attribute value; for an attribute value determined to be the literal type, processing the second attribute information to generate processed second attribute information and comparing the processed second attribute information with the aggregated literal attributes information to determine whether the requested resource matches the available resource types; and for an attribute value determined to be the numerical type, comparing the second attribute information with the aggregated numerical attributes information to determine whether the requested resource matches the available resource types.

Abstract: This disclosure describes systems, methods, and devices related to enhanced time-sensitive networking (TSN) configuration. A device may identify a frame received from a TSN domain comprising wired and wireless TSN traffic. The device may decode the frame to extract one or more fields, wherein the one or more fields comprise bridge parameters. The device may determine based on the bridge parameters whether a port associated with the device is wireless capable.

Abstract: Aspects of the present disclosure include implementing fabric availability and synchronization (FAS) agents within a fabric network. In one example, a first FAS agent executing on a first network device may receive, from a second network device, a command to modify a configuration of a second network device. The first FAS may upgrade the configuration of the first network device based on the command from a current configuration to a new configuration. The first FAS agent increment a state identifier associated with the configuration of the first network device to a new state identifier associated with the new configuration. The first FAS agent may then transmit a control packet that includes the new state identifier. A second FAS agent executing on the second network device may receive the control packet and execute the command to update the configuration of the second network device to the new configuration.

Abstract: A method (500) of network reachability impact analysis includes receiving (502) a plurality of network configuration snapshots (304, 304a-304n) for a network (208). The method also include selecting (504) a first network configuration snapshot (304b) of the network and a second network configuration snapshot (304c) of the network. The method further includes generating (508) a first reachability graph (332a) representing packet reachability of the network for the first network configuration snapshot. The method also includes generating a second reachability graph (332b) representing packet reachability of the network for the second network configuration snapshot. The method also includes computing a reachability differentiation graph (342) identifying a net change to reachability from the first reachability graph (332a) to the second reachability graph (332b). The method further includes generating a reachability differentiation report (352) including a human-interpretable output of the net change to reachability.

Abstract: Systems, methods, and computer-readable media are disclosed for a scalable process for validating multiple paths used for routing network traffic in a network using segment routing. In one aspect, a method includes identifying, by a first network hop, one or more second network hops, for each of the one or more second network hops, determining a corresponding flow label, the corresponding flow label including a corresponding test packet for validating packet forwarding between the first network hop and a corresponding second network hop, and performing a validation process for validating packet forwarding from the first network hop to the corresponding second network hop using at least the corresponding flow label. The method further includes determining a queue of additional network hops to be validated based on a result of the validation process, and iteratively validating packet forwarding for each additional network hop in the queue.
