Optical Line Terminal (OLT) Core of Optical Access Network

The OLT planning strategies with regard to the upstream bandwidth estimation OLT’s upstream bandwidth planning strategies estimate the provisioned volume of upstream bandwidth for each ONU. For example, the number of subscribers per ONU, as well as their past activities (e.g., uploads – cloud storage, video conferencing) influence the estimates. Potential increases in demand in the future are taken into consideration as well. To utilize the available upstream bandwidth, some optimization techniques may be applied, which include dynamic bandwidth allocation. This strategy permits allocation of greater bandwidth to high-demand ONUs and thus optimally makes use of scarce upstream resources.
