A method and apparatus to analyze real-time data transmissions across a network is described. The method may comprise transmitting a sample data stream between source and destination endpoints across a test data path which includes network devices. The method may then compare a measured quality of the received sample data stream with pre-defined quality criteria associated with the network. If the measured quality fails to meet the pre-defined quality criteria, the network devices in the test data path may be identified, device performance data may be obtained, and a network report may be generated based on the device performance data. The device performance data may comprise processor utilization, memory utilization, bandwidth over subscription, buffer over run, and/or a number of non-error packets that are discarded at the network device.

Method and system to identify a network device associated with poor QoS

A method of automatically parsing a network device configuration and generating a representation of one or more configuration commands for a network device that uses a command-line interface, using a grammar-based framework, is disclosed. One or more syntax definitions are received for a grammar associated with the command-line interface. The syntax definitions are compiled into a grammar object that represents the grammar. A configuration of the network device is received. The configuration is parsed using the grammar object. One or more configuration values are created and stored based on parsing the configuration. Using the configuration values, operating system version information, and the grammar object, one or more command-line interface commands may be automatically generated for use in configuring the device or other network management purposes. Further, applications may use the parameter values to customize a graphical user interface, perform range checking, etc.
