Abstract
In a packet switch with databases () used for packet forwarding, the database pieces are identified by version identifiers (V) which are used by the packet switch's modules (LCx, RPM, RPM) in exchanging information on the databases and requesting updates to the databases. For example, if a primary management module fails and the management is transferred to a secondary management module, the secondary management module requests forwarding modules (e.g. line cards) to identify the database pieces stored on the forwarding modules, and to update the databases as needed. Use of version identifiers reduces the amount of data that has to be transferred in connection with such requests.
