我们考虑一个单向的设计方法来解决弹性光网络（EON）中的流量不对称。我们将双向转发器解耦成一对单独的单向发射器和单向接收器，并考虑不同的多流发射器，其使用激光二极管阵列或具有滤波器的宽带激光源来生成多个子载波。为了评估这种单向设计的好处，我们考虑了EON的路由和频谱分配优化问题。建立了基于谱窗平面的整数线性规划模型和高效的启发式算法。仿真结果表明，所提出的单向设计方法可以显着提高容量利用率和最小化网络成本相比，基于双向对称业务流。它也是有效的网络场景与空间流量不对称，需要多周期网络规划。
We consider a unidirectional design approach to tackle the traffic asymmetry in an elastic optical network (EON). We decouple a bidirectional transponder into a pair of separate unidirectional transmitters and unidirectional receivers, and consider different multi-flow transmitters that use either an array of laser diodes or a broadband laser source with filters to generate multiple sub-carriers. To evaluate the benefit of this unidirectional design, we have considered the routing and spectrum allocation optimization problem for the EON. An integer linear programming model and an efficient heuristic algorithm based on spectrum window planes have been developed. Simulation results show that the proposed unidirectional design approach can significantly improve capacity utilization and minimize network cost compared to one based on bidirectional symmetric traffic flows. It is also efficient for network scenarios with spatial traffic asymmetry and where multi-period network planning is required.
