Abstract: PURPOSE: A method for dynamically allocating bandwidths in a GE-PON(Gigabit Ethernet Passive Optical Network) is provided to improve the utilization coefficient of network resources in consideration of the bandwidths requested from ONUs(Optical Network Units). CONSTITUTION: An OLT(Optical Line Termination) divides BW_TOT_AVAIL, a total available bandwidth, by N and obtains the average of the bandwidths requested from ONUs(100). Then the OLT appoints the first ONU among the ONUs that have requested bandwidths(102), and compares RW_REQi, a requested bandwidth, with the average BW_AVG(104). In case that RW_REQi is larger than BW_AVG, the OLT allocates the bandwidth of BW_AVG only(108). However, if RW_REQi is equal to or smaller than BW_AVG, the OLT allocates the whole of the requested bandwidth RW_REQi as BW_ALLOCi, an allocation bandwidth. Then the OLT adds BW_AVG-BW_REQi, the difference between BW_AVG and BW_REQi, to BW_REMAIN(106).

Abstract translation: 目的：提供一种在GE-PON（千兆以太网无源光网络）中动态分配带宽的方法，以考虑从ONU（光网络单元）请求的带宽来提高网络资源的利用系数。 规定：OLT（光线路终端）将BW_TOT_AVAIL（总可用带宽）除以N，并获得从ONU（100）请求的带宽的平均值。 然后，OLT在请求带宽的ONU中指定第一ONU（102），并将所请求的带宽的RW_REQi与平均BW_AVG（104）进行比较。 在RW_REQi大于BW_AVG的情况下，OLT仅分配BW_AVG的带宽（108）。 然而，如果RW_REQi等于或小于BW_AVG，则OLT将整个请求带宽RW_REQi分配为BW_ALLOCi（分配带宽）。 然后，OLT将BW_AVG-BW_REQi（BW_AVG和BW_REQi之间的差别）添加到BW_REMAIN（106）。
