Dynamic bandwidth allocation scheme for network-slicing-based TDM-PON toward the beyond-5G era

Description

<jats:p>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.</jats:p>
