Device for and method of making element appear in shortest network path by minimal decrements and increments

摘要

A device and method of minimally incrementing and decrementing the weights of a minimal number of links in a network to cause a link/node that is not in the shortest path in the network to be in the shortest path by determining the shortest path with link/node, identifying links in this path that are not in the shortest path without link/node, decrementing identified links to make the path the shortest path, identifying a link in the shortest path without link/node not in the path with link/node, incrementing the link, redoing these steps to determine a number of links and modifications to links that would cause the link/node to appear in the shortest path, identifying the set of links and modifications with the fewest links, and modifying the network in accordance with the identified set.
