    摘要： The disclosed technology is directed towards locating and counting unused nodes, such as free Internet Protocol version 4 (IPv4) address blocks. A hierarchical structure of nodes is created from an origin block to a specified lower level, and the hierarchical structure is processed using mapping and eliminating to locate free nodes. A first node group comprises node(s) in use, a second node group identifies intermediate subnets between the first node of the first node group and the specified origin block, and a third node group identifies any subnets hierarchically below node(s) in use. Unused (free) node count information is obtained based on nodes below the origin block that are not in the first node group, the second node group, or the third node group.

    摘要： Aspects of the subject disclosure may include, for example, a method in which a processing system determines a location of a failure in a communication network and a cause of the failure. If the failure cannot be resolved using a recovery feature of the network, the processing system identifies a recovery procedure for resolving the failure, and dispatches an automated vehicle to the failure location; the vehicle is provided with instructions for performing the recovery procedure, which may include replacement of a hardware component of the network. The operations also include determining whether the recovery procedure is successful; if the recovery procedure is not successful, the processing system obtains information via the vehicle regarding the failure, to facilitate human intervention to resolve the failure. Other embodiments are disclosed.

    摘要： Architectures and techniques are presented that improve or increase network security for networks that have network slicing capability. In addition to (or instead of) conventional network slices, various security-based network slices can be defined and/or implemented. Network traffic of a subscriber device can be assigned to one of these security based network slices. Assignment can be based on characteristics of the subscriber device and/or based on the current behavior or role of the subscriber device. Further, in response to determining that a behavior of the subscriber device satisfies a criterion (e.g., a criterion relating to malfeasance or misbehavior, a criterion relating to switching to a maintenance cycle, and so on), reassigning network traffic of the subscriber device from the currently assigned network slice to a different network slice.
