摘要

Known network management systems for managing traffic signals in a network store node/link parameter signals and traffic parameter signals and calculate solutions defining intermediate nodes/links situated between sources and destinations for transporting said traffic signals from said sources to said destinations via said intermediate nodes/links and calculate route information per solution. By storing node/link parameter signals and traffic parameter signals for several situations (like several predictions in the future) and calculating solutions for each situation and then selecting a solution per situation, the network management system will manage the network more advantageously, especially when solutions are compared with each other, and when a solution is selected per situation in dependence of comparison results (comprising similarities/differences between solutions of different situations). Said route information may comprise link load parameters and/or resource consumption parameters and/or fairness parameters and/or throughput parameters.

1. A network management system for managing traffic signals in a network comprising nodes/links, said network management system comprising:
a memory for storing node/link parameter signals defining nodes/links and for storing traffic parameter signals defining said traffic signals to be transported via nodes/links; a calculator coupled to said memory for calculating solutions defining intermediate nodes/links situated between sources and destinations for transporting said traffic signals from said sources to said destinations via said intermediate nodes/links and for calculating route information per solution; a comparator coupled to said calculator for: comparing solutions of a same situation with each other, wherein comparing includes determining an amount of path amendments between one or more pairs of solutions; and comparing solutions of different situations with each other, wherein comparing includes determining an amount of path amendments between one or more pairs of solutions related to different situations; and a selector coupled to said comparator for selecting a solution per situation based on at least one comparison result of the comparing solutions of the same situation and at least one comparison result of the comparing solutions of different situations, wherein said memory comprising node/link parameter signals and traffic parameter signals for several situations and said calculator calculates respective solutions for each situation, wherein each of said several situations corresponds with a prediction in the future related to said traffic signals being transported from at least one node to at least one other node, and wherein the route information comprises at least link load data and resource consumption data.
