在即将到来的5G移动通信时代，移动前端和物联网网络等网络将密集部署海量无线接入点。基于网络分片的时分复用无源光网络(TDM-PON)是一种经济高效地容纳这些接入点的解决方案。它使我们能够通过将每个子网络虚拟隔离在单个TDM-PON上来融合这些具有不同需求的多个网络。为了实现TDM-PON的融合，我们提出了一种动态带宽分配方案，该方案在每个子网络上以不同的方式进行上行带宽分配，以同时满足每个子网络的需求。实验表明，该方案能够同时提供低延迟传输、带宽保证和自动发现过程。
In the coming 5G mobile communications era, a huge number of wireless access points will be densely deployed for networks such as mobile fronthaul and Internet-of-Things networks. A network-slicing-based time-division-multiplexing passive optical network (TDM-PON) is one solution for cost-effectively accommodating these access points. It enables us to converge these multiple networks that have different requirements by virtually isolating each sub-network on a single TDM-PON. To achieve this TDM-PON convergence, we propose a dynamic bandwidth allocation scheme that performs uplink bandwidth allocations in a different manner at every sub-network in order to simultaneously satisfy each sub-network requirement. Experiments show that the scheme can simultaneously provide low-latency transmission, bandwidth guarantee, and an auto-discovery process.
