Abstract

Network recovery of multiple NEs, such as at NMS restart, or at re-establishment of communication after loss of communication with the NMS that provides reduced cost and reduced the elapsed time before the NMS can start performing network monitoring. A method of recovering data from a network element at a network management system comprises the steps of determining whether a data buffer of the network element is valid, if the data buffer of the network element is valid, determining whether the data buffer of the network element contains a database change event not received by the network management system, if the data buffer of the network element is not valid or if the data buffer of the network element contains a database change event not received by the network management system, indicating that the data buffer of the network element is out-of-sync with the network management system, and if the data buffer of the network element is valid and if the data buffer of the network element does not contains a database change event not received by the network management system, indicating that the data buffer of the network element is in sync with the network management system.
