Abstract: A system and method is disclosed of extracting information from real-time network packet data to analyze connectivity data for client devices in a network. The method includes: detecting when client devices initiate a connectivity event; after detecting a connectivity event, waiting a period of time for the client device to either reach or fail to reach a network connected state; after waiting a period of time, recording connectivity event information; and sending the recorded connectivity event information to an analytics system for network incident and/or network congestion analysis.

Abstract: A method for analyzing network incidents within a network and providing prioritized remediation recommendations is disclosed. The method includes: receiving network data and computing a plurality of network incidents from the network data, collecting network incidents related to a particular network issue over a time period and grouping the network incidents according to root-cause symptoms, generating a network incident graph by superimposing groups of network incidents over a network graph, analyzing the network incident graph to identify localized areas with systemic issues; and based on the analysis of the network incident graph, generating and displaying a list of remediation recommendations. Each remediation recommendation includes a systemic issue in the network, a remediation to resolve the issue, and a quantified expected benefit from implementing the remediation.

Abstract: Some embodiments of the invention provide a method for proactively optimizing network performance for a software-defined wide area network (SD-WAN), which connects multiple devices operating in multiple network segments, during an active network flow. The method monitors the SD-WAN for network events related to the active network flow. The method detects a particular network event at a first device in a first segment in the SD-WAN traversed by the active network flow. Based on the particular network event, the method performs a proactive action on at least a second device in a second network segment in the SD-WAN that will be traversed by the active network flows in order to mitigate a potential negative impact of the particular network event on the performance of the SD-WAN to improve overall network performance.

Abstract: Some embodiments provide a method for managing a network. Based on a first set of flow statistics received from network elements in the network, the method identifies a data message flow with degraded performance. The data message flow follows a path, between a first endpoint and a second endpoint through a set of the network elements in the network, that includes multiple segments. The method uses a second set of flow statistics received from the set of network elements to identify a particular segment of the path as a most likely contributor to the degraded performance of the particular flow. The method initiates a corrective action to resolve the degraded performance for the data message flow based on the identification of the particular segment.

Abstract: Some embodiments provide a novel method that performs an automated process that identifies features of an IoT device connected to a network, and based on the identified features specifies, without an administrator input, one or more network policies (e.g., security policies) to apply to packets sent or received by the IoT device. The method of some embodiments also performs automated processes that (1) analyze packet flows to and from the IoT devices to identify dynamic network behavior of these devices, and then (2) specify network policies based on the identified dynamic network behavior.
