Abstract: Problem Diagnosis Automation System (PDAS) automates the diagnosis of repetitive problems and the enforcement of preventive measures across a network. Automation assets across the network include Network Intent (NI) inside the no-code platform. A Network Intent Cluster (NIC) clones a NI across the network to create a group of NIs (member NIs) with the same design or logic. A subset of Member NIs can be executed according to user-defined conditions based on the member device, the member NI tags, or signature variables. A Triggered Automation Framework (TAF) matches the incoming API calls from a 3rd party system to current incidents and installs the automation (e.g., NI/NIC) to be triggered for each call. It may include: Integrated IT System defining the scope and data of the incoming API calls; Incident Type to match a call to an Incident; and Triggered Diagnosis to define what and how the NIC/NI is executed.
