Abstract
A network device, such as a router or switch, has a CPU and a memory operable to receive, store and output computer code. The code includes device configuration files, traffic pattern files, and standard-behavior-output template files adapted for detecting network device functional defects and bottlenecks. The device is operable in a testing mode to act as either a Device Testing Doctor (DTD) or a Device Under Test (DUT), in which it loads into or accepts from a related, interconnected and similarly configured and operable network device selected ones of the device configurations, transmits to or receives from the other device selected ones of the input traffic patterns, compares its own output or that of the other device in response to the input traffic pattern with selected ones of the standard-behavior-output templates, and detects a network device defect or bottleneck in itself or in the other device based on the comparison.
