基于SDN的云RAN中的动态回程网络配置
Dynamic Backhaul Network Configuration in SDN-based Cloud RANs
摘要：
移动接入网中基站的协调是减少有害干扰并向用户提供高数据率的重要途径。当集中基站的数据处理（称为云RAN）时，可以容易地实现这样的协调机制，如多个BS向用户设备发送数据的协调多点（CoMP）。这种集中化还对回程网络提出了对于到基站的连接的高容量和低延迟的显著要求。这些要求可以通过（a）基站数据处理功能的灵活布置和（b）动态分配回程网络资源来减轻。我们展示了这两种技术是如何通过使用启发式算法来增加密集移动接入网络中基站协调的可行性。此外，我们提出了一个原型实现我们的方法的基础上软件定义网络（SDN）与OpenDaylight和Maxinet。
英文摘要：
The coordination of base stations in mobile access networks is an important approach to reduce harmful interference and to deliver high data rates to the users. Such coordination mechanisms, like Coordinated Multi-Point (CoMP) where multiple BSs transmit data to a user equipment, can be easily implemented when centralizing the data processing of the base stations, known as Cloud RAN. This centralization also imposes significant requirements on the backhaul network for high capacities and low latencies for the connections to the base stations. These requirements can be mitigated by (a) a flexible placement of the base station data processing functionality and by (b) dynamically assigning backhaul network resources. We show how these two techniques increase the feasibility of base station coordination in dense mobile access networks by using a heuristic algorithm. We furthermore present a prototype implementation of our approach based on software defined networking (SDN) with OpenDaylight and Maxinet.
