ABSTRACT:
Methods and systems for monitoring a data path on a network routing device are described. The data path includes a plurality of devices on the network routing device and an interface. Data packets are moved on the network routing device using the devices and communicated to and from a network via the interface. A process for detecting a defective device on the network routing device is executed. The process is a self-contained process that is executed within the data path, allowing a defect in the data path to be detected, localized and recovered from.
