Abstract
A quality of service (QoS) aware medium access control (MAC) protocol is presented for next generation OFDMA-PONs. The end-to-end delay and network throughput are investigated in the presence of class-of-service and service-level differentiation. In addition, this paper proposes a new dynamic subcarrier allocation (DSA) algorithm. The monitoring window time technique is used where OLT measures the state of the ONU's queue instead of exchanging traditional report messages. As a result, the end-to-end packet delay of high and middle SLAs is less than 0.7 ms even if the ONU offered load is 1.0. The packet delay of the high priority traffic class regardless of SLA levels is however less than 0.6 ms. The total network throughput is 97% of total capacity.
