ITR: Forward Error Correction Codes and Protocols for Next-Generation Optical Networks

提出的研究目标是开发一种框架，将前向错误控制（FEC）与光网络中的带宽管理和路由相结合，该框架可以了解光信道特性，并可以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。针对光网络时变特性的要求，将开发自适应误差保护FEC技术。支持新型FEC方案的网络管理协议将被开发和测试，以证明其在下一代光网络中的效率和效益。新的网络路径选择算法将用于异构环境中的主路径和备份路径，以满足可变网络请求和物理层的约束。该项目还将说明在何种程度上可以使用组合编码和网络管理技术来放松对光通信材料和设备的限制。

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.
