Abstract:
A method to facilitate fast network management protocol replies in large tables, comprising:receiving a request for a next row in a network management protocol table; comparing an object identifier associated with the network management protocol table in the request with a pre-calculated object identifier; and if the object identifier matches the pre-calculated object identifier, responding to the request with a pre-calculated response, otherwise searching a management information base for the next row in the network management protocol table, calculating a response, wherein the response includes data from requested columns of the next row, and responding to the request with the response; wherein, before responding to the request with the pre-calculated response or responding to the request with the response, selecting a candidate next row in the network management protocol table, creating the pre-calculated object identifier for the candidate next row, saving the pre-calculated object identifier, creating the pre-calculated response for the candidate next row, wherein the pre-calculated response includes data from requested columns of the candidate next row, and saving the pre-calculated response; wherein receiving the request for the next row from the network management protocol table includes: locating a protocol data unit in the request; and determining the object identifier within the protocol data unit; wherein determining the next row in the network management protocol table includes: decoding the object identifier in the protocol data unit; and searching for an object related to the object identifier in the management information base.
