Abstract

Space-division multiplexing (SDM) is regarded as one of the most promising technologies to satisfy the explosively growing internet traffic. Elastic optical networks with SDM is one of the newest network architectures for network planning in the future. However, the resource allocation problem in these networks becomes more complicated due to the expansion of spatial dimensions. In this paper, we propose a novel channel-based integer linear programming (ILP) model for the problem of routing, space, and spectrum assignment (RSSA) in consideration of space lane change in SDM-EON. To evaluate our model, we make a comparison with the slot-based model [15] via simulation experiments. Different spatial switching granularities are considered in our performance evaluation because they will greatly change the detailed results of allocation. By the numerical results, we find that our novel model has an overwhelming advantage over the previous slot-based one in computing time for the optimization process.

一种新的基于信道的路由、空间和频谱分配问题模型

空分多路复用(SDM)被认为是满足爆炸性增长的互联网流量的最有前途的技术之一。SDM弹性光网络是未来网络规划的最新网络架构之一。然而，由于空间维度的扩大，这些网络中的资源分配问题变得更加复杂。本文针对SDM-EON中考虑空间信道变化的路由、空间和频谱分配问题，提出了一种基于信道的整数线性规划(ILP)模型。为了评估我们的模型，我们通过仿真实验与基于槽的模型[15]进行了比较。我们在性能评估中考虑了不同的空间切换粒度，因为它们会极大地改变分配的详细结果。数值结果表明，该模型在优化过程的计算时间上明显优于以往的基于槽的模型。
