Dynamic Subcarrier Allocation for P2MP Connections

This paper proposes a solution for dynamically allocating subcarriers in a point-to-multipoint connection in the upstream direction. Using Digital Subcarrier Multiplexing a single carrier can be divided into several subcarriers. An ILP was proposed to dynamically allocated subcarriers in various traffic scenarios allowing for an increased number of edge nodes serviced. Significant capital and energy cost reductions were shown in comparison to traditional methods.
