,the Ethernet Passive Optical Network(EPON) has become a promising broadband access network,and has attracted more attention.

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.

Optimization design of optical distribution network in EPON;

Full Services Access Network System of Cable Television Based on EPON;

The features of the frame architecture of the Ethernet Passive Optical Net(EPON)system are described.

EPON (Ethernet Passive Optical Network) technology represents the convergence of mature Ethernet technology with PON and is regarded as the best candidate technology of next generation access network because of its low-cost, broad bandwidth, simple maintenance, excellent performance-to-cost ratio and providing multi-service.

Ethernet Passive Optical Networks (EPONs), which converge the simplicity and universality of Ethernet facilities and large-capacity, steady-performance and low-cost of PONs, has emerged as one of the most promising solution for broadband-access-network bottleneck problem.

By analyzing MAC protocol in Ethernet Passive Optical Network(EPON),it proposes a new Dynamic Bandwidth Allocation(DBA) algorithm for supporting QoS.
