This paper proposes an adaptive dual-clocking algorithm, which can effectively solve the problem of light-load deterioration in Ethernet Passive Optical Network(EPON) without increasing the delay of Expedited Forwarding(EF) service, and decrease the delay of Assured Forwarding (AF), Best Effort(BE) and other low-priority services. Its clocking can be changed according to actual situations and it improves the slot waste to a certain extent. A system working model with OPNET is established to realize simulation, the result indicates that the algorithm can decrease the average network delay and enhance the network turnover.
