Abstract

For allowing an efficient consumption of resources of a physical substrate network a method for operating at least one virtual network on a substrate network is claimed, especially within a framework of a self-organizing model for optimizing resource consumption of the substrate network, wherein the virtual networks are including a plurality of virtual nodes each being assigned to respective substrate nodes of the substrate network and wherein two adjacent virtual nodes of the same virtual network are connected by a virtual link which is corresponding to one or more respective substrate node links, including the following steps: Identifying a traffic pattern within at least two substrate nodes with regard to the resources individually consumed by the virtual networks; reallocating of the resources depending on an evaluation of the identified traffic patterns for optimizing resource consumption within the substrate nodes, wherein the identifying step and the evaluation and decision to execute the reallocation of resources is performed locally at each individual substrate node. Further, an according virtual network environment on a substrate network is claimed, preferably for carryin…
