Abstract:
1. A method for dynamically allocating a bandwidth based on a hierarchical weight round robin scheme, comprising: reading reports received for logical link identifications (LLID) that are allocated to optical network unit (ONUs), wherein the LLIDs are each classified into one of a plurality of classes, in the reading of reports, a class to process is selected recursively from a high class to a low class, and report values are sequentially read and gates generated for LLIDs in the selected class; restricting the read report value to be less than a maximum gate value set for a corresponding LLID; generating a gate having a length corresponding to the restricted report value; and deleting a report after generating a gate using it, wherein the reading of the reports received and generating the gate for each LLID comprises: wherein the reading of reports, the restricting of the read report value, the generating of the gate, and the deleting of the report are repeatedly performed in sequence for LLIDs.
