The goal of the proposed research is to develop a framework for forward error control (FEC) in combination with bandwidth management and routing in optical networks that is aware of optical channel characteristics and can allocate network resources to optimize system performance. The FEC schemes are based on low-density parity-check codes and iterative joint detection/decoding techniques that mitigate (linear and nonlinear) distortion and crosstalk. The adaptive error protection FEC techniques will be developed that are tailored for the time-varying characteristics of requirements of optical networks. Network management protocols supporting novel FEC schemes will be developed and tested to demonstrate their efficiency and benefit in next generation optical networks. Novel network path selection algorithms will be developed for primary and backup paths in heterogeneous environments that satisfy constraints imposed by both variable network requests and the physical layer. The project will also give the extent to which the combined coding and network management techniques can be used to relax constraints on optical communications materials and devices.

提出的研究目标是在光网络中开发一种结合带宽管理和路由的前向差错控制(FEC)框架，该框架能够感知光信道特性并能够分配网络资源以优化系统性能。FEC方案基于低密度奇偶校验码和迭代联合检测/解码技术，以减轻(线性和非线性)失真和串扰。自适应差错保护FEC技术将被开发，以适应光网络需求的时变特征。支持新的FEC方案的网络管理协议将被开发和测试，以展示它们在下一代光网络中的效率和益处。将为满足可变网络请求和物理层施加的约束的异类环境中的主路径和备用路径开发新的网络路径选择算法。该项目还将给出联合编码和网络管理技术在多大程度上可以用来放松对光通信材料和设备的限制。
