Abstract

Methods of managing databases and corresponding database systems are disclosed. A method of managing a database comprising determining, prior to removal, a time interval corresponding to said maximum time span across database entries to be retained in the database; dividing said time interval into at least first and second time slices; and updating at least the first and second slice databases with database events. After the time span corresponding to the duration of the first time slice, the method includes replacing the first slice database with the second slice database and creating a new second slice database as the former Two copies of the database.

Description

technical field [0001] The invention relates to a database with an aging mechanism and a method of managing the database. Specifically, the present invention relates to dynamic databases in network devices such as routers, switches, network bridges, and network service managers. Background technique [0002] Databases that are dynamically updated and may only take up a limited amount of storage space need to be constantly checked for obsolete or old entries. Purging, ie deleting or overwriting these entries helps maintain a functional database. Such purges may generally be referred to as "aging" of the database, ie removal of old database entries. For example, aging can be done through data collection efforts. The removal of this data reduces the size of the database. Aging events are usually computationally intensive, especially when hierarchical aging effects must be considered, ie the effect of deleting one entry results in the need to update other database entries fu...
