Recent Dynamic Bandwidth Allocation Algorithm Methods in Ethernet Passive Optical Network

The “last mile” bandwidth bottleneck problem can be best solved by using Ethernet Passive Optical Network (EPON). EPON is a promising technology to implement the Fiber To The Home solution. Dynamic bandwidth allocation (DBA) is one of the critical issues in the design of the EPON system that has been studied by many researches. This paper introduces the fundamental concepts on EPONs, its protocol and its bandwidth allocation. We also compile and classify the research works in order to provide the state-of-art of the DBA algorithms. The advantages and disadvantages of each classification is provided. The classifications provide insightful presentations of the prior work on EPONs which will help the researches to choose the most suitable algorithm as according to the needs.
