DETERMINING CAUSE OF SUB-OPTIMAL NETWORK DEVICE PERFORMANCE

摘要

In one example, a server classifies a subnetwork of network devices as performing sub-optimally. The server also classifies a geographic cluster of network devices as performing sub-optimally. The server determines whether a particular sub-optimally performing network device is in both the subnetwork and the geographic cluster. If it is determined that the particular sub-optimally performing network device is in both the subnetwork and the geographic cluster, the server identifies the particular sub-optimally performing network device as performing sub-optimally due to a performance issue with a Wide Area Network to which the particular sub-optimally performing network device belongs.
