1. A computer-implemented method for generating a checksum value associated with configuration settings of a network, the computer-implemented method comprising:

  • receiving network configuration information associated with the network;

    processing the network configuration information to identify a hierarchy of objects associated with the network; and

    applying at least one algorithm to different levels of the hierarchy of objects to generate a substantially unique checksum value associated with the network configuration information;

    wherein applying the at least one algorithm includes performing operational steps of;

    i) in a first direction, shifting a current checksum value in a first register by a number of bits;

    ii) adding a data value to the current checksum value in the first register;

    iii) producing a temporary checksum value in a second register based on a portion of bits of the current checksum value in the first register;

    iv) in a second direction opposite the first direction, shifting bits of the temporary checksum value in the second register; and

    v) applying an operation to a combination of the current checksum value in the first register and the temporary checksum value in the second register and storing results of the operation as the current checksum value in the first register.
