作为电信网络中流量工程或能耗方面有意义的模拟和优化工作的基础，合适的模型是必不可少的。这不仅涉及现实的网络拓扑结构，而且还涉及地理分布和流量的时间动态模型，以及对网络组件和技术的假设。本文从一家大型国有航空公司的实际出发，推导出了一个模型。应用网络和流量模型，我们展示了它的使用，提出了各种优化的情况下，节能电信。在这里，我们专注于负载自适应性采用睡眠模式的网络硬件，其中几个约束的可重构性的网络随着时间的推移被认为是。
As a basis for meaningful simulation and optimization efforts with regard to traffic engineering or energy consumption in telecommunication networks, suitable models are indispensable. This concerns not only realistic network topologies but also models for the geographical distribution and the temporal dynamics of traffic, as well as the assumptions on network components and technology. This paper derives such a model from the practice of a large national carrier. Applying the network and traffic model, we demonstrate its use by presenting various optimization cases related to energy-efficient telecommunication. Here, we focus on load adaptivity by employing sleep modes to the network hardware, where several constraints on the reconfigurability of the network over time are considered.
