Abstract:
Enclosed herewith is a method for protecting a link in an optical network configured for transmitting digital data employing a predetermined modulation format which comprises a number of symbols in a constellation diagram. A binary address is associated with each symbol. The modulation format allows for a constellation distortion, according to which the relative positions of constellation points in the constellation diagram are varied in a predetermined way by a predetermined degree. The method comprises the steps of: A) partitioning the traffic in two or more priority classes, B) mapping higher priority traffic to predefined bit positions within the binary symbol addresses, C) evaluating the quality of a predetermined protection link, D) determining a degree of distortion such that a desired transmission quality for the transmission of the traffic of the highest priority class or classes via said predetermined protection link and a desired transmission quality for the full traffic via said given link are simultaneously ensured, and E) employing said distorted constellation diagram for transmission of digital data over said given link.

Claim (Index 13):
A control device for controlling the protection of a link in an optical network,\n said control device configured to be operatively connected to a transmitter and a receiver associated with said link, said transmitter being configured for transmitting digital data employing a predetermined modulation format, wherein\n said modulation format uses a constellation diagram comprising a number of symbols, \n each symbol is represented by a point in an n-dimensional Euclidean signal space, wherein n\u22651, \n a binary address is associated with each symbol, and \n said modulation format allows for a constellation distortion, according to which the relative positions of constellation points in the constellation diagram are varied in a predetermined way by a predetermined degree as compared to a non-distorted constellation, \n said transmitter further being configured for\n partitioning the data to be transmitted over the link in two or more priority classes, and \n mapping higher priority traffic to predefined bit positions within the binary symbol addresses, \n the control device further being configured for\n evaluating quality of a predetermined protection link via which a part of the traffic could be transmitted in case of failure of the given link, \n determining a degree of distortion of the constellation diagram such that a desired transmission quality for the transmission of the traffic of the highest priority class or classes via said predetermined protection link and a desired transmission quality for the full traffic via said given link are simultaneously ensured, and \n instructing said transmitter and said receiver to employ a distorted constellation diagram with the determined degree of distortion for said transmission of digital data over said given link.
