Abstract
Systems and methods for synchronizing a plurality of databases are provided for a plurality of geographically dispersed computers in receive-only communication. Each change made to a master database in a central computer is broadcast to a plurality of remote computers, each containing a replica of the master database, via a packet having an assigned next-broadcast-number and a sequential next-sequence-number. Each remote computer has means for comparing the next-broadcast-number and next-sequence-number of each received packet with the last-broadcast-number-received and last-sequence-number-received from a previous packet, and for selectively updating its replica database.
