APPLICATION SESSION-SPECIFIC NETWORK TOPOLOGY GENERATION FOR TROUBLESHOOTING THE APPLICATION SESSION
Publication number: 20240137264Abstract: 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.Type: ApplicationFiled: December 29, 2023Publication date: April 25, 2024Inventors: Jisheng Wang, Xiaoying Wu, Yedunandan Siddalingappa-Vitalapur, Abhiram Madhugiri Shamsundar, Robert J.
