我们研究了光城域接入网络中3层C-RAN架构的功率感知动态DU/CU布局。我们的研究表明,基于流量的DU和CU位置的自适应放置和重新配置可以显著降低能耗,而服务阻塞的增加却可以忽略不计。
We investigate power-aware dynamic DU/CU placement for a 3-layer C-RAN architecture in optical metro-access networks. We show that adaptive placement and reconfiguration of both DU and CU locations based on traffic allows to significantly decrease energy consumption, paying off only a negligible increase in service blocking.
