Abstract: Techniques are described that detect areas with insufficient radio frequency (RF) coverage in a wireless network. A network management system (NMS) determines one or more service level expectation (SLE) metrics for each client device in a wireless network. The SLE metrics are aggregated to each access point (AP) in the wireless network, and each AP is assigned an AP score based on the aggregated SLE metrics. To identify potential coverage holes, the NMS groups APs having poor AP scores. If a root cause of the poor AP scores cannot be automatically resolved and if the poor AP scores persist for a predetermined period of time, the group of APs is determined to represent a true coverage hole. The NMS may generate a notification regarding recommended corrective actions to the customer and/or IT personnel.

Abstract: A network device can automatically select an execution plan from a set of possible execution plans that cause a first set of traffic assignments in a network to be changed to a second set of traffic assignments. A traffic assignment indicates assignments of the traffic to one or more tunnels, internal routes and/or peer links to be utilized for routing traffic received at provider edge routers through a network to prefixes. A traffic assignment can have various parameters such as bandwidth, transmission costs etc. Each execution plan has one or more steps, and each step has one or more traffic assignment changes progressing from the first set of traffic assignments to the second set of traffic assignments. The network device can automatically select an execution plan based on an evaluation metric determined for each execution plan. The evaluation metric can be a cost based metric or a quality based metric.

Abstract: Techniques are described by which a network management system (NMS) receives, from a plurality of access points (APs) configured to provide a wireless network, received signal strength indicator (RSSI) values. The NMS generates, based on the RSSI values, a graph of the plurality of APs, wherein the graph of the plurality of APs includes a plurality of clusters, wherein each cluster comprises a subset of the plurality of APs that are grouped based on strength of connectivity between the subset of the plurality of APs. The NMS generates, based on the graph, an upgrade plan to upgrade the plurality of APs, wherein the upgrade plan comprises a plurality of batches, wherein each batch includes a selection of at least one AP from each of one or more of the plurality of clusters. The NMS sends the upgrade plan to an orchestrator to execute the upgrade plan.

Abstract: A device receives policy information indicating a policy to be implemented for an application hosted by multiple cloud domains, and receives, from the multiple cloud domains, different application resource tags and addresses associated with the application. The device maps the different application resource tags to a generic identifier, and associates the policy with the generic identifier and with the addresses associated with the application. The device provides, based on associating the policy with the generic identifier and with the addresses associated with the application, the policy to the multiple cloud domains to permit the multiple cloud domains to implement the policy.

Abstract: A virtualization system may receive, by a physical hardware device driver of a kernel of a guest OS of the virtualization system and from a process of the guest OS, one or more control messages to control a physical hardware device. The virtualization system may determine, by the physical hardware device driver and based on the second-type physical hardware device address included in the one or more control messages, a first-type physical hardware device address associated with the physical hardware device. The virtualization system may update, by the physical hardware device driver, the one or more control messages to include the first-type physical hardware device address, and may send, by the physical hardware device driver and to an emulated physical hardware device of a hypervisor of a host OS of the virtualization system, the one or more control messages.

Abstract: A first router generates session establishment metrics for use in network path selection. For example, a plurality of routers connect a client device to a network service instance hosted by a server. A first router is connected to the network service instance via first and second paths. The first router receives session performance requirements for a session between the client device and the network service instance. The first router forwards, along the first path, network traffic for the session by modifying a first packet of the session to include a session identifier for the session. The first router determines that session establishment metrics for the session do not satisfy the session performance requirements. In response, the first router forwards, along the second path, the network traffic for the session by modifying a second packet of the session to include the session identifier for the session.

Abstract: In an example, a method includes computing, by a computing device, for a segment routing policy that specifies a bandwidth constraint for the segment routing policy, first shortest paths through a network of network nodes, wherein each shortest path of the first shortest paths represents a different sequence of links connecting pairs of the network nodes from a source to a destination; in response to determining, by the computing device based on the bandwidth constraint for the segment routing policy, a link of one of the first shortest paths has insufficient bandwidth to meet a required bandwidth for the link, increasing a metric of the link; computing, by the computing device, for the segment routing policy that specifies the bandwidth constraint, based on the increased metric of the link, second shortest paths through the network of network nodes; and provisioning the second shortest paths in the network of nodes.
