摘要:Abstract: EPON is a common communication and networking technology used in distribution network. In order to allocate the bandwidth of the EPON network effectively, the transmission slot is allocated by the interleaving method with adaptive period. For solving the waiting and delay caused by the fixed polling cycle, it is necessary to analyze and forecast the traffic of the ONU. In order to reduce the delay, an algorithm for predicting the arrival time and period duration of a single EPON cycle data frame by using the least mean square polynomial and the least mean square adaptive filtering method is proposed. Using the analysis of the frame arrival time and the next cycle duration, calculate the amount of data accumulated in the next cycle, and then allocate the corresponding bandwidth and transmission cycle. Simulation results show that the algorithm can adapt to different load and traffic burst networks, which can effectively reduce the network delay.
