Abstract
In the upstream link of EPON, numerous ONUs In the reverse link of the EPON network, numerous ONUs receive the privileges to use the optical medium from the scheduler of the LOT, but not through the competition with others. Therefore, it is very important to select a proper DBA algorithm to allocatethe frequency band to each ONU in an effectively and fair manner. In our preceding study, we proposed the RC-DBA algorithm that complements many problems in existing DBA algorithms. In this paper, we designed the MAC scheduler for the OLT, which the proposed algorithmwas applied to and implement it in the FPGA. In addition, in order to verify the operation of the scheduler, we developed the embedded Linux based testbed.
