SELF-HEALING CAM DATAPATH IN A DISTRIBUTED COMMUNICATION SYSTEM

摘要

Various embodiments include a method for monitoring a Content Addressable Memory (CAM). The method may include performing CAM hardware error polling, determining that a stored data soft error or datapath link error is present, comparing the number of stored data soft errors or datapath link errors to a threshold, when the number of stored data soft errors or datapath link errors is less than the threshold, invoking a master line-card stored data refresh process, determining a datapath port link error's detection; and when a datapath port link is down or persistent errors are present, invoking a datapath port link recovery process including hardware error polling to ascertain whether the recovery process was successful

1. A method for monitoring a Content Addressable Memory (CAM) comprising:
performing CAM hardware error polling; determining that a stored data soft error or datapath link error is present; comparing the number of errors to a threshold;
when the number of errors is less than the threshold, invoking a master line-card stored data refresh process; determining a datapath port link error's detection; and
when the datapath port link is down or persistent errors are present, invoking a datapath port link recovery process including hardware error polling to ascertain whether recovery operation was successful.
