METHOD FOR MORE EFFECTIVE DATA TRANSMISSION IN AN OPTICAL TELECOMMUNICATION NETWORK IN WAVELENGTH MULTIPLEX OPERATION OF OPTICAL WAVELENGTHS, WHEREIN THE OPTICAL TELECOMMUNICATION NETWORK HAS A PLURALITY OF NETWORK ELEMENTS AND TWO SUPERORDINATE NETWORK NODES, OPTICAL TELECOMMUNICATION NETWORK, COMPUTER PROGRAM AND COMPUTER PROGRAM PRODUCT

摘要

There is provided a method of more effectively transmitting data in a wavelength division multiplex (WDM) optical telecommunications network of different optical wavelengths, the optical telecommunications network having a first parent network node, a second parent network node, and further a plurality of network elements. wherein the plurality of network elements comprises at least a first network element and a second network element, wherein the telecommunications network has an optical transmission path, wherein the optical transmission path- The first parent network node and the first network element and- The first network element and the second network element and further- The second network element and the second parent network node directly or indirectly interconnects, wherein the optical transmission link further connects the first parent network node and the second parent network node with each other, so that the optical transmission link is closed topologically annular, wherein the annular closed optical transmission path the first network element at least indirectly connects via a first signal path or via a second signal path to the first higher-level network node and wherein the annular closed optical transmission path, the first network element either at least indirectly via another first signal path or via a further second signal path to the second parent network node connects, wherein the first signal path and the further first signal path overlap at least in a first portion of the optical transmission path, wobe i overlap the second signal path and the further second signal path at least in a second subregion of the optical transmission path, wherein both the first and second signal path and the further first and further second signal paths are disjoint to each other and complement each other to the optical transmission path,wherein in a normal operation mode of the optical telecommunication network for data transmission- Between the first network element on the one hand and the first parent network node of the data transport on the first signal path of the optical transmission path and- Between the first network element and the second parent network node of the data transport on the other first signal path of the optical transmission path is used (dual homing).
