Abstract
A method for polling a plurality of remote processing units includes establishing a table of active and inactive remote processing units, sequentially polling each of the active processing units, at the conclusion of polling the active processing units, polling an inactive processing unit after which all of the active processing units are again polled. This sequence is repeated until all the active and inactive processing units have been polled. If in polling a processing unit, a response to the poll message indicates a change of status of the polled processing unit has occurred, the table is accordingly updated to reflect the current status of the processing unit.
