DYNAMIC ALLOCATION METHOD AND APPARATUS OF HIERARCHICAL WRR

摘要

A dynamic bandwidth allocation and apparatus according to a hierarchical weight value round robin method are provided to increase overall throughput in allocating an uplink bandwidth to each ONU(Optical Network Unit). The first table(11) stores information for dynamic bandwidth allocation including a report value of each LLID(Logical Link Identification). When a report message transmitted by an ONU is received, a report writing unit(20) records a report value of the received message in the first table. A dynamic gate generating unit(30) reads the report value of each LLID sequentially from the first table without a predetermined period to generate a gate with a length corresponding to the report value, and deletes the gate-generated report value from the first table.
