摘要
Disclosed herein are systems, methods, and computer readable-media for detecting and identifying network faults. The method includes recording cyclic redundancy check (CRC) errors gathered by a data stream analyzer, if the number of CRC errors exceeds a threshold, sending a notification to an automated fault manager which (1) analyzes the number of CRC errors, (2) determines a cause of the CRC errors, and (3) takes appropriate corrective action based on the analysis. The method can further include storing CRC error measurements in a log organized by date and time, analyzing stored CRC error measurements to anticipate future CRC errors, and taking preventive action in advance of anticipated future CRC errors. The automated fault manager can be a rule-based fault/performance management system. The notification can be a Simple Network Management Protocol (SNMP) trap. The data stream analyzer can be an MPEG transport stream analyzer. The automated fault manager can be a video provider or a part of a network management system. The threshold can be either dynamic or static and can be based on video stream priority.
