Abstract:
1. An apparatus for dynamic debugging of a multi-node network, said network comprising an infrastructure including a plurality of devices, each device adapted for communicating timing messages between nodes according to a timing protocol governing communication of timing information among nodes in the network for synchronizing system clocks at said nodes, said apparatus comprising: a plurality of probe links interconnecting each node of said multi-node network with a probe device, said probe device monitoring data included in each timing message received at each node as communicated according to said timing protocol, and extracting timing state information from said timing message; means for processing said extracted timing state information from each message at said probe device to determine existence of a trigger condition at a node, said processing of said extracted timing state information including: generating a control message for receipt by all nodes in said network via said probe links for halting operation at said node and recording data useful for debugging purposes, whereby debug information is collected at each node at the time of a first error detection and collected dynamically at execution time without manual intervention.
