ABSTRACT
A Passive Optical Network (PON) is a single, collective optical fiber that used low-cost optical splitters to divide the single fiber into split strands feed individual subscribers. PONS are called passive because, other than at the CO (Central Office) and subscriber endpoints, there are no active electronics inside the access network. With the development of services offered by the Internet, the "last mile" restricted access problems keep it up to increase step by step. Many algorithms were developed for making TDM EPON efficient similar to Scheduling (No class Solution) and Priority Swapping, IPACT etr. These all algorithms have problems like delay, QoS and channel under- utilization. We focused the well-organized bandwidth utilization in TDM EPON by managing time slots within ONUs and reducing latency and increasing quality of service. Our Rahul Fixed Priority Enhance Classes Bandwidth (RFPECB) algorithm is an intra-ONU bandwidth allocation algorithm, which is used to enhance the network performance by evaluating the parameters like channel underutilization, delay and Quality of Service. The issues which are lacking in the already made algorithms are being resolved with our RFPECB Algorithm. The main problem time slots management issue solved in RFPECB algorithm.
