IP over WDM网络中数据中心的存在会产生热节点场景，导致数据中心节点的功耗显著增加。在本文中，我们调查的功耗与数据中心和最终用户之间的IP在WDM网络传输数据。我们研究两个问题。首先，我们优化了IP over WDM网络中数据中心的位置，以最小化功耗。其次，我们研究了将可再生能源引入具有数据中心的IP over WDM网络，并评估了是否将数据中心定位在可再生能源旁边或将可再生能源传输到数据中心的问题。结果表明，在可再生能源存在的情况下优化数据中心位置可以节省高达71%的电力消耗。
The presence of data centres in IP over WDM networks can create a hot node scenario leading to a significant increase in the power consumption of data centre nodes. In this paper, we investigate the power consumption associated with transporting data between data centres and end-users in IP over WDM networks. We study two problems. Firstly, we optimize the location of the data centres in the IP over WDM network so as to minimize the power consumption. Secondly, we investigate introducing renewable energy to IP over WDM networks with data centres and evaluate the problem of whether to locate data centres next to renewable energy or to transmit renewable energy to data centres. The results show that optimizing the data centre locations in the presence of renewable energy sources can save up to 71% of the power consumption.
