Abstract

The elastic optical networks paradigm offers a competitive solution in terms of resource utilization to cope with the ever-increasing traffic demand. Specifically, the ability to make a number of previously fixed transmission parameters tunable, for example the data rate or channel spacing, requires an evolution of the node architecture. To fully benefit from elasticity, the data plane should evolve towards a software-defined architecture. In this paper, we report the work carried out in the ICT IDEALIST project and in particular the data plane solutions towards 1Tb/s optical networks with flexgrid and flex-rate technology. Flexibility requires changes in optical cross-connect, transponder as well as in the digital layer. The consortium builds pre-commercial experimental testbeds to validate the proposed building blocks and to analyze candidate applications.

理想的弹性光网络数据平面解决方案

弹性光网络模式在资源利用方面提供了具有竞争力的解决方案，以应对日益增长的流量需求。具体来说，要使许多先前固定的传输参数(例如数据速率或信道间隔)可调，需要对节点体系结构进行改进。为了充分受益于弹性，数据平面应该向软件定义的体系结构发展。在本文中，我们报告了在ICT IDEALIST项目中开展的工作，特别是针对采用灵活网格和灵活速率技术的1Tb/s光网络的数据平面解决方案。灵活性要求光交叉连接、应答器以及数字层的变化。该联盟建立了预商用实验试验台，以验证提议的构建模块并分析候选应用。
