Method and system for controlling optical network
First Claim
1. A method for controlling an optical network composed of network elements NEs, with the aid of a network controller NC being in communication with said network elements, the method comprising:
- collecting, by the network controller NC, information on the network elements from said NEs,whenever a desired change in the network is requested by a Network Management System NMS, simulating, within the network controller, operation of the network with the requested change based on the collected information on the network elements,making, in the network controller, a decision on acceptability of the requested change, andif the decision is positive, causing implementation of the requested change in the network.

Abstract
A technique is described for controlling and optical network composed of network elements (NEs), with the aid of a network controller (NC) being in communication with the network elements. The technique includes collecting, by the network controller NC, information on the NEs therefrom, and, whenever a change in the network is requested, simulating within the NC operation of the network with the requested change and based on the collected information. The NC makes a decision on acceptability of the requested change, and may then cause implementation of the requested change in the network.

9. A network controller NC for managing an optical network comprising a number of network elements NEs,
the controller being capable of communicating with the NEs for collecting information there-from; -
said network controller NC comprising a network simulator NS, while the NS is capable of simulating operation of said network based on the collected information and data on a desired change in the network, said data being received from a Network Management System NMS; said network controller NC being also adapted, based on the simulation results, to make a decision whether the desired change is acceptable, and to cause implementation of said change if the decision is positive. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. An optical network comprising a number of network elements NE controllable with the aid of a network controller NC, each of the NE being provided with an individual ID tag capable of communicating with said NC and comprising a memory block for storing individual parameters of the network element NE;
the NC being capable of communicating with said NE for collecting information stored in their respective ID tags, and provided with a network simulator NS capable of simulating operation of the network using said information for a desired change in the network requested by a Network Management System NMS.
