CYCLE TIME DETERMINING METHOD AND APPARATUS BASED ON PASSIVE OPTICAL NETWORK

摘要

PURPOSE: A cycle time determining method and an apparatus based on a passive optical network are provided to satisfy the delay limit range of real time traffic by determining a cycle time according to transmission distance. CONSTITUTION: A distance information input unit receives distance information between an OLT(Optical Line Terminal) and ONT(Optical Network Terminal)(210). A distance section determiner decides the distance interval between OLT and ONT(Optical Network Terminal). An equalized round trip delay determiner decides Teqd(equalized round trip delay)(240). The cycle time determiner decides a cycle time(250).
