| Abstract: | By analyzing the data transmission modes in EPON system and the theory of Dynamic Bandwidth Allocation(DBA),the applications of DBA algorithm in the Ethernet Passive Optical Networks(EPON) system were researched.A new DBA mechanism based on Quality of Service(QoS) was proposed.Experiments show that the EPON system with the QoS-based DBA mechanism can allocate upstream bandwidth flexibly to improve the bandwidth utilization and quality of service according to the differences of business grades and the dynamic bandwidth allocation algorithm. |
