ABSTRACT:
A device for communicating with other devices over a communication system is disclosed which has the capability of being a segment reporter and if it is not a segment reporter, of determining when it should become a segment reporter. The device includes a transmitter and receiver such that if the device is a segment reporter, it can transmit periodically a report request message requiring other devices to transmit report messages back to it and it can transmit an integrity map to all other devices based upon the report messages which it received from those devices. If the device is not a segment reporter, it can transmit report messages back to the segment reporter in response to a report request message and it can monitor the segment reporter in order to assume the segment reporting function if the segment reporter fails. The device will store the integrity map it receives from the segment reporter.
