| Popis: |
We propose a new access network architecture named Cloud-based PON. It separates the C-Plane/D-Plane functions of PON-OLT and consolidates the former in a datacenter. We identify the increase in upstream delay (due to the increase in Round Trip Time) as a technical obstacle to the realization of the concept. In order to solve this problem, we propose a predictive Dynamic Bandwidth Allocation algorithm that takes advantage of the correlation characteristic between the upstream and downstream traffic. Simulations verify that our proposal improves the delay and the bandwidth utilization compared to the existing related works. |
