Some embodiments of the invention provide a method for detecting and remediating anomalies in an SD-WAN that includes a controller, an enterprise datacenter, and multiple branch sites each having at least one edge node that includes a set of packet processing stages. At the controller, the method receives from a particular node of a particular branch site a flow notification indicating detection of an anomaly on the particular node. Based on the anomaly, the method dynamically generates trace monitoring rules that specify one or more flows to be traced and provides the trace monitoring rules to the particular node and at least one other node of another branch site. From the particular node and the at least one other node, the method receives trace monitoring results collected in response to the provided trace monitoring rules, and analyzes the results to identify any anomalies and dynamic actions to correct the anomalies.

A system and method for mitigating anomalies in a network device. One or a combination of mitigation actions may be pre-programmed into a plurality of customer premises equipment (CPE) devices. The mitigation actions may be available as temporary or permanent work arounds as problems are detected that match known or discovered patterns of log events. Unsupervised machine learning techniques may be used to identify and correlate new patterns of log events with device anomalies or malfunctions. When a new pattern of log events is discovered and correlated to an anomaly or malfunction in a group of CPE devices, the discovered pattern may be written to the group of CPE devices with instructions to use particular ones of the mitigation actions. The CPE devices can then, in examples, monitor their own logs to detect the patterns and implement one or more of the mitigation actions.

A system and method for efficient fast failover of a primary link to a secondary link comprising monitoring an amount of user packets on said primary link and sending synthetic packets on said secondary link at a predetermined rate based on said amount of user packets wherein said predetermined rate is changed as a function of change in said amount of user packets.

A computing system receives, from a client device, a first request for access to a single page application associated with the computing system. A gateway of the computing system intercepts the first request before it reaches a shell service associated with the single page application. The gateway sends a second request for the single page application to the shell service. Based on the single page application request, the gateway determines that the shell service is experiencing a failure. Responsive to determining that the shell service is experiencing a failure, the gateway retrieves, from a content delivery network, a uniform resource locator (URL) associated with a time-lapse hypertext markup language (HTML) of the single page application. The gateway redirects the client device to the time-lapse HTML of the single page application using the URL.

Systems and methods are provided to enable packets of network traffic to be hashed to available network gateway. Each packet can include a route table with a pool of network gateways as a next-hop of the packet. A network device may intercept the packet and hash the packet to a network gateway of the pool of network gateways. The network gateway can correspond to a stateful network router and the stateful network router can transmit the packet to a network appliance. The network device can monitor and perform health-checks on the network gateways, the stateful network routers, and the network appliances. The network device can remove components that are no longer healthy or available and can add components that subsequently become healthy.

A method of managing communication services provided by a service provider, comprising obtaining a prediction of a portion of the quantity of the served devices that received substandard communication services from the service provider during a period of time, obtaining an acceptable deviation from the prediction of the portion of served devices, making a determination that a quantity of the served devices that received substandard communication services from the service provider during the period of time is outside of a range, and performing an action set to initiate remediation of the service provider. Specifically, the determination is based on the prediction of the portion of the quantity of served devices, and the acceptable deviation.

A method includes determining, by a computer device, device information for a network device communicatively coupled to the computer device. The method includes retrieving, from a server device, a configuration file corresponding to the device information as determined. The method includes resetting the network device using the configuration file as retrieved. The method includes clearing user-addressable storage locations of the network device. The method includes outputting an indication of whether resetting the network device was successful and whether clearing the user-addressable storage locations of the network device was successful.

In one embodiment, an illustrative method herein may comprise: determining, by a device, that a request for an online resource has not yet provisioned the online resource; determining, by the device, one or more errors responsible for the online resource not yet being provisioned; determining, by the device, whether the one or more errors have since been resolved; retrying, by the device and in response to the one or more errors having since been resolved, the request for the online resource to be provisioned; and deferring, by the device and in response to the one or more errors remaining unresolved, an attempt to request that the online resource be provisioned.

Systems and methods are provided herein for analyzing root-causes of network access failures in a wireless network. In response to detecting that a client device experiences a network access failure that prevents communication with a server device, a method, according to one implementation, includes a step of analyzing the network access failure to predict one or more root-causes. Also, the method includes beginning a remediation procedure for remediating the one or more root-causes.

This disclosure describes systems, methods, and devices related to network outage management. A method may include receiving a first indication of a first cable system outage. The method may include identifying a start time associated with the first cable system outage, and determining, based on the start time, a time period during which to refrain from generating a service ticket indicative of the first cable system outage. The method may include determining that the first cable system outage has not ended at an end time of the time period, and receiving a second indication of a second cable system outage. The method may include determining that the second cable system outage begins during the time period and has not ended at the end time. The method may include generating and sending a service ticket indicative of the first cable system outage and the second cable system outage.
