The Ethernet passive optical network is being regarded as one of the best solutions for next-generation optical access solutions. In time-division multiplexing-passive optical network technology (TDM-PON), the dynamic bandwidth allocation (DBA) plays a crucial role in efficiently and fairly allocating the bandwidth between all users. Moreover, the quality of service (QoS) is also an essential requirement to support triple-play services. However, many proposed DBA mechanisms are still unable to solve the idle period problem and enhance the differentiated services (DiffServ), which will decrease the quality of overall system performance. Therefore, this paper proposes a generic QoS-aware interleaved dynamic bandwidth allocation (QA-IDBA). The QA-IDBA can operate adaptively bi-partitioned interleaved scheduling with QoS-based predictive limit bandwidth allocation (QP-LBA) and excess bandwidth reallocation …
