Method and apparatus for re-synchronizing a network manager to its network agents

摘要

A method and apparatus for resynchronizing a network manager to its agents. Each object instance of an agent in an object-oriented management scheme is assigned two special attributes, namely, DATASYNCH and UNIQUEID. UNIQUEID is a unique number assigned to each object instance. DATASYNCH essentially is a counter which is incremented each time a change occurs to an object instance. When resynchronization is necessary, the manager requests the UNIQUEID and DATASYNCH attributes from its agents and compares those values with the corresponding values stored in its database. With respect to any object instance which does not match in both its UNIQUEID and DATASYNCH attributes to the manager's database, the manager uploads those object instances from the agent's database and/or revises its database accordingly. <IMAGE>
