Generalized Shaping and Precoding for Flexible Adaptation in Dynamic Optical Networks

该方案将光纤信道的编码和均衡扩展和推广到预均衡（预编码）和信号整形方案。与DSL宽带接入类似，在光传输中也应使用发送端预均衡（预编码）和信号整形。鉴于光纤通道的非线性特性，必须对这些方法进行深入的评估，并使其适合于光纤通道。此外，预编码和整形必须无缝集成到未来动态网络的拓扑结构中。为此，必须开发合适的监测方法来支持预编码和整形方法。为了提高未来光网络的性能，需要优化网络层和传输层遥测数据的交互。将特别关注动态网络操作环境下的灵活性和适应性。

This proposal addresses the extension and generalization of coding and equalization for fiber-optical channels to pre-equalization (precoding) and signal shaping schemes. Similar to, e.g., DSL broadband access, transmitter-side pre-equalization (precoding) and signal shaping should also be used in optical transmission. In view of the nonlinear behavior an in-depth assessment of these methods must be conduced and they have to be suitably adapted to the fiber-optical channel. In addition, precoding and shaping must be seamlessly integrated into the topology of future dynamic networks. For this purpose suitable monitoring methods have to be developed to support the precoding and shaping methods. The interaction of telemetry data obtained at both the network layer and the transport layer should be optimized to improve the performance of future optical networks. Special focus will be given to flexibility and adaptivity in the context of dynamic network operation.
