Abstract
An existing network configuration is assessed, and potential changes to the existing configuration are identified that provide the greatest incremental improvements to the performance of the network. In a preferred embodiment, the user of the system identifies the maximum number (N) of changes that may be implemented in an existing network, and the system provides a set of possible reconfigurations, each requiring fewer than N changes. The user is presented a display of the potential improvement provided by each set as a function of the number of changes in the set, so that the relative incremental gain can be easily visualized. The objective function of the optimization may include conventional load-balancing objectives, or other objectives, such as a global minimization of path lengths.
