A passive optical network (PON) is a telecommunications network that uses point-to-multipoint fiber to the premises in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises. A PON consists of an optical line terminal (OLT) at the service provider’s central office and a number of optical network units (ONUs) near end users. A PON reduces the amount of fiber and central office equipment required compared with point-to-point architectures. A passive optical

NT 1310 NETWORK TOPOLOGY PAPER: KENDAL JEFFERSON Network topology refers to layout of a network and how different nodes in a network are connected to each other and how they communicate. Mesh Topology: in a mesh network‚ devices are connected with many redundant interconnections between network nodes‚ in a true mesh topology every node has a connection to every other node in the network. There are two types of mesh topologies: Full mesh occurs when every node has a circuit connection it to every

Logical vs. Physical Design of a Network In the world of network design‚ there are two common design types; the logical network design and the physical network design. A logical network design can be described as how the network will be structured‚ basically all logical aspects of the network. According to Webopedia‚ "the logical topology is the way that the signals act on the network media‚ or the way that the data passes through the network from one device to the next without regard to the

Performance Issues of Routing Protocols in MANET ABSTRACT A mobile ad-hoc network is an assortment of wireless mobile hosts‚ which establishes a momentary network without any assist of centralized administrator. The characteristics of an ad-hoc network can be explored on the base of routing protocols. The dynamic topology is the vital characteristic in which nodes frequently change their position. In the ad-hoc networks‚ there are mobile nodes such as personal digital assistance (PDA)‚ smart phone

wide area network that connects computer systems around the globe. I order to understand the internet one must look to the basic network. There are two types of networks. Peer to peer (P2P) and Client / provider networks. In a peer to peer network no node has more authority than another node. File sharing is possible on a P2P network but there may be multiple copies of a document at different revision states. It is for this reason that corporations and firms use Client provider networks at their
