The present document relates to a method for providing load information of an optical data transmission network, the method comprising the steps of:
- receiving information regarding the current state of the optical data transmission network including network topology information and information regarding currently established optical transmission links;
- identifying network connections for which a potential transmission request may be received;
- pre-calculating, based on the information regarding the current state of the optical data transmission network, optical transmission link information for each identified network connection, said optical transmission link information at least including transmission path information;
- establishing, for each potential transmission request related to a certain network connection, a link-based cost-of-change metric, the link-based cost-of change metric being indicative for the resource utilization in the optical data transmission network caused by the respective transmission request and the currently established optical transmission links;
- accumulating the established link-based cost-of-change metrics in order to obtain a node-based cost-of-change metric, said node-based cost-of-change metric being indicative for the load of the optical nodes of the optical data transmission network; and
- providing load information based on the node-based cost-of-change metric, said load information indicating the potential load of the nodes of the optical data transmission network based on the potential transmission requests. |
