The importance and necessity of end-to-end fault and performance problem detection in wide area production networks increases with the complexity of the paths, the diversity of network components performance, and dependency on the network. Network monitoring provides insight into the state and performance of the network and whether it is behaving as expected and whether changes in the network h...

Ethernet Passive Optical Network (EPON) is a point to multipoint network architecture and suitable for carrying Internet Protocol Television (IPTV) service because it provisions higher bandwidth for downstream, but it also cannot satisfy the bandwidth requirement of tens of thousands of IPTV channels and carry these channels simultaneously. Previous papers had proposed some multicast mechanisms...

The harmonic in distribution systems becomes an important problem due to an increase in nonlinear loads. This paper presents a new approach based on a graph algorithm for optimum placement of passive harmonic filters in a multi-bus system, which suffers from harmonic current sources. The objective of this paper is to minimize the network loss, the cost of the filter and the total harmonic disto...

In the present paper, we have planned the deployment of passive, active and splitting optical devices employed in passive optical network (PON) standards such as giga-passive optical networks (GPON), broadband passive optical network (BPON) and Ethernet passive optical network (EPON) has been modeled and investigated over wide range of the affecting parameters. The utilization of the transport ...

Fiber optic access networks have been considered a definitive solution to the constant need for increasingly higher bandwidths. For this reason, PON (Passive Optical Network) grown enormously in recent years, offering different solutions end customer, whether it is residential or business. However, project complex and time-consuming process. This paper focused on tool design that, when combined...

In order to achieve the combined advantages of optical broadband network and wireless network, the concept of Fiber wireless (FiWi) access network has been evolved. There are various research issues in FiWi network. Survivability and energy efficiency are of main concern. In this paper the main objective is to propose optimal segmentation of FiWi network, using adaptive energy segmentation algo...
