In an integrated fiber and wireless (FiWi) access networks, multipath routing may be applied in the wireless subnetwork to improve throughput. Because of different delays along multiple paths, packets may arrive at the destination out of order, which may cause TCP Performance degradation. As all traffic in a FiWi network is sent to the Optical line terminal (OLT), the OLT serves as a convergence node which naturally makes it possible to re-sequence packets at the OLT before they are sent to the internet. However the challenge is that OLT must re-sequence packets effectively with a very small delay to avoid a performance hit. To overcome this problem, Scheduling Algorithms (FIFO, Priority Queuing, DRR, and MDRR) at Optical Line Terminal (OLT) is used effectively to reduce Packet Reordering and to improve TCP Performance. Simulation results show that MDRR scheduling algorithm is effective in reducing the packet reordering
