The need for optical parallelization, where multiple optical channels are used in parallel by means of Spatial Division Multiplexing (SDM), is driven by the imminent capacity limit of optical fibers. This has gainedsignificant attention recently as it has been shown that without parallelization,the future requirement of about 20b/s/Hz spectral efficiency will bebeyond the Shannon limit, and thus unachievable with the current technologies.Consequently, the high-speed Ethernet systems have already resorted to parallelization in 40/100~Gigabit Ethernet (40/100GE) standards. Therein, the recently proposed elastic opticalnetworks based on elastic spectrum allocation and Orthogonal Frequency Division Multiplexing (OFDM) technologyhave emerged as a potentially transformative solution. This is due to its fundamentalcapability to actually slice or parallelize the optical spectrum into asequence of frequency slots and modulate signals on frequency slots in formof sub-carriers that can match parallel end-system streams.To deliver on the true potential of this rapid trend, a three-year researchprogram is proposed including three main research thrusts, namely, (i)Architectural Design - focusing on addressing architectural challenges in networks deploying parallel transmissionalong with the network migration from fixed to flexible spectrum allocation, towards ascalable capacity increase beyond the 100~Gb/s serial transmission rates, (ii) Modeling and Algorithmic Design - focusing on modeling of optical parallel transmission, including parallel routing, flexible assignment of advanced modulation formats, aswell as taking advantage of flexible optical spectrum allocation, and,(iii) Network Coded Parallel Transmission - applying network coding to paralleltransmission, with the goal of scalable system design as well as to investigate whether network coding can contribute to fault-tolerant and reliable high-speed optical system transmission.To test the proposed concept on its validity and usability, we plan to useanalysis, simulations, as well as emulations. In its entirety, the proposed research program provides a unique platform forfundamental research across a diverse spectrum of formal sciences (e.g.,information theory, fiber transmission, network modeling, and algorithms), aswell as computer engineering (e.g., network and protocol architecture, parallel computing).

光纤的容量限制迫在眉睫，这就需要光并行化，即通过空分复用（SDM）并行使用多个光信道。近年来，这一问题引起了人们的广泛关注，因为如果不进行并行化，未来对20 b/s/Hz的频谱效率的要求将超过Shannon极限，无法用现有的技术实现，因此，在40/100~千兆以太网（40/100 GE）标准中，高速以太网系统已经求助于并行化。其中，最近提出的基于弹性频谱分配和正交频分复用（OFDM）技术的弹性光网络已经成为一种潜在的变革性解决方案。这是由于它的基本能力，实际切片或并行化的光谱到一个序列的频率槽和调制信号的频率槽的形式的子载波，可以匹配并行的终端系统流。为了实现这一快速趋势的真正潜力，提出了一个为期三年的研究计划，包括三个主要的研究方向，即，（i）架构设计-侧重于解决部署并行传输的网络中的架构挑战，以及从固定频谱分配向灵活频谱分配的网络迁移，以实现超过100 Gb/s串行传输速率的可扩展容量增加，（ii）建模和并行设计-侧重于光并行传输的建模，包括并行路由，高级调制格式的灵活分配，以及利用灵活的光谱分配，以及（iii）网络编码并行传输-将网络编码应用于并行传输，的目的，以及研究网络编码是否有助于容错和可靠的高速光系统传输。为了测试所提出的概念的有效性和可用性，we plan计划to useanalysis分析，simulation模拟，as well as the emulations仿真.总体而言，拟议的研究计划提供了一个独特的平台，用于跨各种正式科学的基础研究（例如，信息理论、光纤传输、网络建模和算法），以及计算机工程（例如，网络和协议体系结构、并行计算）。
