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.

所提出的研究的目标是开发一个框架，前向差错控制（FEC）结合带宽管理和路由在光网络中，是知道光信道特性，可以分配网络资源，以优化系统性能。FEC方案是基于低密度奇偶校验码和迭代联合检测/解码技术，减轻（线性和非线性）失真和串扰。自适应错误保护FEC技术将被开发，是针对光网络的时变特性的要求。支持新的FEC方案的网络管理协议将被开发和测试，以证明它们在下一代光网络中的效率和好处。新的网络路径选择算法将开发的主要和备份路径在异构环境中，满足由两个变量的网络请求和物理层的约束。该项目还将给出组合编码和网络管理技术可以在多大程度上用于放宽对光通信材料和设备的限制。
