  • Method and apparatus to facilitate fast network management protocol replies in large tables
    Patent number: 6789082
    Abstract: One embodiment of the present invention provides a system that facilitates fast network management protocol replies in large tables. The system operates by first receiving a request for a next row from a network management protocol table. The system then compares the object identifier in the request with a pre-calculated object identifier. If the object identifier matches the pre-calculated object identifier, the system responds to the request with a pre-calculated response. If the object identifier does not match the pre-calculated object identifier, the system searches a management information base for the next row in the network management protocol table. Next, the system calculates a response, which includes data from requested columns of the next row. The system then responds to the request.
