Abstract An upcoming capable technology named as Next generation Ethernet passive optical network (NG-EPON); to handle enormous bandwidth and effective distribution requirements for prospective Internet based services. Standardization procedures for NG-EPON are in progress. Transmission of data traffic from Optical Network Units (ONUs) towards Optical Line Terminal (OLT) in NG-EPON is carried out through four wavelengths each operating at a data rate of 25Gbps. Dynamic wavelength and bandwidth allocation (DWBA) algorithms are needed for the efficient arbitration of the bandwidth resources between the subscribers. In this paper, we have proposed two different DWBA algorithms for NG-EPON; DWBA-I and DWBA-II. DWBA-I is a Quality-of-Service based algorithm that has been designed to manage the different types of data traffic in NG-EPON. DWBA-I performs better than the different existing DBA algorithms in terms of packet delay, completion time and packet drop ratio. DWBA-II is an algorithm designed to meet the system requirement specifications of NG-EPON and handle traffic requirements of subscribers in a cost effective manner. DWBA-II algorithm is comparatively analyzed and evaluated with First-FitDWBA and Modified-IPACT algorithms. Performance of DWBA-II is better on the basis of average delay, grant utilization, completion time and packets drop ratio. Performance of DWBA-I and DWBA-II has been evaluated through simulation results.

1 Introduction Requirement of overwhelming and fast data services is consistently rising every day. With the modern technologies like Internet of Things (IoT), where simple objects have network connectivity and for sure their functionality needs network connectivity for the sending and receiving of data. Some of IoT applications like smart homes, smart objects, smart grids and smart cities will dominate the world [1]. Trends are showing that transmission of data in an access network is risingup rapidly and will reach thousands of Exa-byte in future [2]. Demand of more bandwidth crafts the path for commercial implementation of Passive Optical Networks (PON). High Data transmission capacity and cost effectiveness are main benefits of PON [3]. Ethernet PON (EPON) is a capable solution for access networks which can handle high bandwidth requirement of end users. EPON combi
