Method and system for triggering a protocol analyzer

摘要

A protocol analyzer is provided including a monitoring state machine for tracking a communication protocol. A trigger mechanism triggers a trace by the analyzer when the state of the protocol differs from the monitoring state machine. The state of the protocol differs from the monitoring state machine when no state change occurs in a pre-defined time period, which may be defined for a given state change. The state of the protocol also differs from the monitoring state machine when a different state change takes place to that indicated by the monitoring state machine.
