PROBLEM TO BE SOLVED: To provide a method for efficiently utilizing port capacity in an IP network. SOLUTION: The present invention provides a method for avoiding demand forecast errors in a network topology model having a plurality of nodes, by monitoring and controlling the quantity of a selected port type at a node. The method comprises determining the actual quantity of a selected port type at a node; setting a forecast of the quantity of the port required; setting a forecast period for the ports, wherein the forecast period is a function of the time required to change the quantity of the ports; setting a threshold value to generate alerts, wherein the threshold value is a function of the forecast period; monitoring the node for a forecast change; if a forecast change is found, then computing the difference between the actual quantity and the forecast quantity; if the difference is greater than the threshold value, then generating an alert and forwarding the alert to a user.
