A system and method for diagnosing connection and communication in an industrial machine. The electronic processing system includes a CAN bus, an ethernet network, and a plurality of devices connected to the CAN bus and the ethernet network. The plurality of devices includes at least one controller programmed to run one or more software applications. A connectivity check is performed to obtain CAN connection status data and ethernet connection status data for the plurality of devices. The CAN connection status data and the ethernet connection status data is analyzed to determine a likely cause of a device connection issue. A solution to the device connection issue is output to a user based on the analyzed data.

A network management system (NMS) is described that provides a granular troubleshooting workflow at an application session level using an application session-specific topology from a client device to a cloud-based application server. During an application session of a cloud-based application, a client device running the application exchanges data through one or more access point (AP) devices, one or more switches at a wired network edge, and one or more network nodes, e.g., switches, routers, and/or gateway devices, to reach a cloud-based application server. For a particular application session, the NMS generates a topology based on network data received from a subset of network devices, e.g., client devices, AP devices, switches, routers, and/or gateways, that were involved in the particular application session over a duration of the particular application session. In this way, the NMS enables backward-looking troubleshooting of the particular application session.

Rapid channel failure detection and recovery in wireless communication networks is needed in order to meet, among other things, carrier class Ethernet channel standards. Thus, resilient wireless packet communications is provided using a physical layer link aggregation protocol with a hardware-assisted rapid channel failure detection algorithm and load balancing, preferably in combination. This functionality may be implemented in a Gigabit Ethernet data access card with an engine configured accordingly. In networks with various topologies, these features may be provided in combination with their existing protocols.

Described herein are systems, methods, and software to identify causes of connectivity issues in a computing environment. In one example, a computing system monitors network characteristics associated with the computing system and identifies an error notification from a service on the computing system that indicates a connectivity issue with one or more other computing systems. In response to the error notification, the computing system identifies additional network characteristics associated with connections to the one or more other computing system and determines one or more probable causes of the connectivity issue based on the network characteristics and additional network characteristics. The computing system can then generate a summary using the one or more probable causes.

A parser model may be used with software-defined applications or controllers. A network topology may be detected and based on the change in the network topology, a network device may filter certain network data traffic for processing by a software-defined network controller.

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.
