APPARATUS AND METHOD EFFICIENT DYNAMIC BANDWIDTH ALLOCATION FOR TDMA BASED PASSIVE OPTICAL NETWORK

摘要

An apparatus and a method efficient dynamic bandwidth allocation for a TDMA based passive optical network are provided to reduce a delay problem by allocating remaining uplink bandwidths to all ONUs(Optical network Units) evenly. A class queue information storage(100) stores a band allocation period for each T-CONT type as well as band amount information. An allocation check table unit(200) checks the received band allocation period received from the class queue information storage. The amount of a band which can be allocated is determined according to the checked period for band allocation. A band allocator(300) re-allocates the remaining uplink bandwidth for each T-CONT type.
