Abstract
A method of synchronizing the information held in a switching database associated with a switching function of a data switching node, with a data network node identifier record associated with a management processor enabling a managed mode thereof is provided. An entry of the switching database is modified. A status specifier corresponding to the modified entry is set to signify the modification thereof. An inspection of the switching database is initiated on the expiration of an adjustable timer, and the information held in modified switching database entries is synchronized with the data network node identifier record. This method of synchronization of the information held in the switching database spreads out of burst changes thereof over time. The advantages are derived from the use of a more economical management processor while providing the same or enhanced levels of service of the data switching node.
