Abstract: In general, techniques are described for providing Hot-Root Standby in Global Table Multicast (GTM) environments. For example, in such GTM environments, normally a single unicast route to the customer multicast source (“C-Source”) will be available to egress provider edge (PE) routers. As described herein, ingress PE routers may advertise multiple routes to a C-Source, including unicast routes that include Route Import Extended Communities, which are imported by egress PE routers. This enables an egress PE router to have multiple paths to the C-Source, and the egress PE router may generate multiple C-multicast source tree joins for respective ingress PE routers in order to receive respective multicast streams sourced by the C-Source from the ingress PE routers.

Abstract: Techniques are described for monitoring application performance in a computer network. For example, a network management system (NMS) includes a memory storing path data received from a plurality of network devices, the path data reported by each network device of the plurality of network devices for one or more logical paths of a physical interface from the given network device over a wide area network (WAN). Additionally, the NMS may include processing circuitry in communication with the memory and configured to: determine, based on the path data, one or more application health assessments for one or more applications, wherein the one or more application health assessments are associated with one or more application time periods for a site, and in response to determining at least one failure state, output a notification including identification of a root cause of the at least one failure state.

Abstract: Techniques are described by which a network management system (NMS) is configured to provide identification of root cause failure through the detection of network scope failures. For example, the NMS comprises one or more processors; and a memory comprising instructions that when executed by the one or more processors cause the one or more processors to: generate a hierarchical attribution graph comprising attributes representing different network scopes at different hierarchical levels; receive network event data, wherein the network event data is indicative of operational behavior of the network, including one or more of successful events or one or more failure events associated with one or more client devices; and apply a machine learning model to the network event data and to a particular network scope in the hierarchical attribution graph to detect whether the particular network scope has failure.

Abstract: In some implementations, a non-ingress node of one or more label-switched paths (LSPs) may identify a resource issue event. The non-ingress node may identify, based on identifying the resource issue event, one or more notification-requester stacks included in a data structure. The non-ingress node may generate one or more resource notification messages that each include a respective notification-requester stack of the one or more notification-requester stacks. The non-ingress node may send the one or more resource notification messages based on the one or more notification-requester stacks.

Abstract: Disclosed are methods and systems for determining combinations of system parameters that indicate a root cause of a system level experience deterioration (SLED). Some of the disclosed embodiments generate a decision tree from a first class of operational parameter datasets. Rules are derived from the decision tree. Filtered rule sets for feature parameters included in the system parameters are then determined. Pairs of features within a particular dataset that each satisfy their respective filtered rule sets are indicative of a root cause of the degradation, at least in some embodiments.

Abstract: A device may receive an input associated with deploying a virtual firewall on a computing device. The device may determine a first set of characteristics associated with the virtual firewall and a second set of characteristics associated with a hypervisor associated with the computing device. The device may automatically tune the virtual firewall based on the first set of characteristics and the second set of characteristics. The device may deploy the virtual firewall after tuning the virtual firewall.

Abstract: Methods of deriving location information of a wireless device include deriving, in the continuous domain, a location of a wireless device and at least one time and location varying path loss function parameter. The coordinates and parameter are derived based on signal strength measurements made at the wireless device, with the measured signals originating from a plurality of wireless transmitters, such as access points. The derived path loss function parameter can include one or more of a path loss exponent parameter, an intercept parameter, a receiver antenna gain parameter, transmitter antenna gain parameter, or a transmit power parameter.

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: An edge services controller may use a service scheduling algorithm to deploy services on Network Interface Cards (NICs) of a NIC fabric while incrementally scheduling services. The edge services controller may assign services to specific nodes depending on their available resources on these nodes. Available resources may include CPU compute, DPU compute, node bandwidth, etc. The edge services controller may also consider the distance between the services that communicate with each other (i.e., hop count between nodes if two communicating services are placed on separate nodes) and the weight of communication between the services. Two services that communicate heavily with each other may consume more bandwidth, and putting them further apart is more detrimental than keeping them closer to each other, i.e., reducing the hop count between each other depending on the bandwidth consumption due to their inter-service communications.
