| Summary: | 碩士 === 元智大學 === 資訊工程學系 === 104 === PON system has been chosen as one of the fiber-to-the home/building/curb/distribution - point (FTTx) technology deployed worldwide which provide the access network architectures with heterogeneous services for multitude users. Fault protection capability and recovery mechanism that able to guarantee the system quality of service (QoS) level are some of the mandatory features required to provide certain level of service to its subscribers. The limitation of standardized PON technologies in providing better resiliency in the network brought the need of further enhancement in the PON architecture. The Software-Defined PON architecture provides flexibility in fault protection and recovery protection with the capability of using SDN to dynamically adjust the system in fault conditions. Simulation results show that our proposed architecture is capable in maintaining overall QoS performance in terms of packet delay, mean jitter, packet loss and throughput in various fault condition.
