Ethernet Passive Optical Network (EPON) provides a solution to overcome the ever increasing bandwidth demand in the access network of the communication infrastructure. It is normally studied using simulation, but for proof of concept, a testbed is also needed. Current testbed are based on Application-Specific Integrated Circuit (ASIC) and Field-Programmable Gate Array (FPGA) which are not easily configurable...
Ethernet Passive Optical Network (EPON) is one of the most promising technologies for FTTX deployed by service providers at the access network. Dynamic Bandwidth Allocation (DBA) for the upstream traffic can help optimize the network bandwidth utilization. This paper discusses a centralized DBA called as Universal DBA (UDBA) algorithm that supports quality of service (QoS) of the upstream traffic...
One of the best options to support fiber to the home is Ethernet passive optical network (EPON) as it provides high bandwidth as well as it is cost effective. However, the issues arise in the EPON system nowadays is the bandwidth allocation. There are numerous research works that are able to allocate the upstream bandwidth dynamically to the optical network units (ONUs). In this paper, we compile...
Quality of Service (QoS) is of concern in Ethernet Passive Optical Network (EPON) in supporting real time traffic. This paper describes a centralized dynamic bandwidth allocation (DBA) algorithm in supporting the QoS inside both the optical line terminal and optical network units for upstream traffic. The DBA algorithm is called Universal DBA and it has been compared with other DBA algorithm to prove...
Ethernet Passive Optical Network (EPON) has gained the interest of many researchers nowadays as it is one of the best technologies to overcome congestion in the local loop between the customer and local exchange. Many network simulators exist in order to study EPON, but the simplest method to study EPON is using MATLAB. However, in order to study EPON using MATLAB, the traffics need to be generated...
In upstream Ethernet passive optical network (EPON) transmission, timeslot needs to be allocated as the needs to share a single fiber from a splitter to the optical line terminal (OLT) can cause a collision. The allocation is usually being studied using simulations, but it does not take into account the physical parameters. This paper shows a study on static bandwidth allocation (SBA) in upstream...
Ethernet passive optical network (EPON) is becoming more popular since the users demand more bandwidth each day. A lot of simulation studies have been done in order to study the upstream EPON transmission, but they are less accurate due to assumed parameters and it does not take into account the physical parameters and the non-linear effects of the optical components. Therefore, this paper presents...
