  • Managing monotonically increasing counter values to minimize impact on non-volatile storage
    Patent number: 6925523
    Abstract: Reducing writes to non-volatile storage in a system for tracking sequence numbers in a communications protocol. In a system which tracks sequence numbers, a sequence number base is kept in non-volatile storage. During normal operation, the value in non-volatile storage is not rewritten until it exceeds the base value in non-volatile storage plus a predetermined update constant. On startup, the sequence number is set to the value in non-volatile storage plus the predetermined update constant.
