Abstract
An apparatus and method for improving network efficiency for data transfer utilizing partial node discovery a during system recovery are disclosed. Upon retrieving a saved last sequence number associated with a network element (“NE”) from a database in a network management system (“NMS”), a process of the partial node discovery obtains a current last sequence number associated with the NE from the NE. After identifying missing sequence numbers associated with the NE, sequence events associated with the NE in the database are updated in accordance with the missing sequence numbers.
Claims20
A method for network recovery, comprising:
- retrieving a saved last sequence number associated with a first network element (“NE”) from a database in a network management system (“NMS”);
- obtaining a current last sequence number associated with the first NE from the first NE;
- identifying missing sequence numbers associated with the first NE in response to the saved last sequence number and the current last sequence number;
- and
- synchronizing event status associated with the first NE in accordance with the missing sequence numbers.
A network system, comprising:
- a first network element (“NE”) capable of storing each sequence number indicating network activities in a first event history table;
- a network management system (“NMS”) coupled to the first NE via a connection and capable of performing a partial node discovery, wherein the NMS includes,
- a comparator module configured to compare a saved last sequence number associated with the first NE and a current last sequence number from the first NE;
- and
- a synchronizing module coupled to comparator module and configured to synchronize sequence numbers associated with the first NE in a database in the NMS in response to a result of comparison from the comparator module.
A method for obtaining network information, comprising:
- retrieving a saved last sequence number of a first network element (“NE”) from a database in a network management system (“NMS”);
- obtaining a last-send event sequence number from an event history table in the first NE via a first connection;
- and
- loading sequence events between the saved last sequence number and the last-send event sequence number from the event history table to the database.
