The most important challenge in an Ethernet Passive Optical Network (EPON) is bandwidth allocation. This is because it is a mandatory service to satisfy the end users' service level agreement (SLA). Dynamic allocation of bandwidth on the diversified characteristics of services such as high definition video, audio cloud computing resource sharing, and virtual reality games is required, especially in point-to-point and multipoint-to-point architectures. Hence, we propose an integrated Unified Dynamic Bandwidth Allocation Scheme (UDBAS) framework for wired and wireless network devices. Our proposed UDBAS framework can provide superior execution of the process of bandwidth partitioning with regard to the acceptance probability and bandwidth utilization, particularly when short-term variations in bandwidth requirements occur. More specifically, owing to the requirement of bandwidth at each customer premises, the present scheme is not efficient for scheduling bandwidth management. Therefore, in this paper, we introduce a UDBAS scheme that is based on the predictive user's bandwidth requirement and regulates bandwidth resources. We show both analytically and by simulation that the proposed scheme can be efficiently applied to an EPON network. |
