| Abstract: | Dynamic bandwidth allocation algorithm is one of the key technologies in EPON system. Existing dynamic bandwidth allocation algorithms with cycle-polling mechanism mostly have the disadvantage of time wasting between polling cycles .The paperpresents a new idle-time eliminating channel transmission scheme. Theoretical analysis and numerical calculation prove that the new scheme can effectively eliminate the idle time and improve the efficiency of upstream link utilization. |
