...Network Topology Paper Assignment 1 Unit 3 Mr. Swailes The study of Network Topology recognizes 8 basic topologies * Point to point * Star * Bus * Mesh * Tree * Hybrid * Daisy chain * Ring Point to point- The simplest topology is the permanent link between two end points Star-in a local area network with a star topology. Each network host is connected to a central hub with a point-to-point connection to a central node called a hub or switch. Bus- In local area networks where Bus Topology is used, each computer is connected to a single Bus cable. A signal from the source travels in both directions to all machines connected on the Bus cable until it finds the intended recipient. If the machine address does not match the intended address for the data, the machine ignores it. However, if the data matches it is accepted. The bad part of this topology is that it has a single point of failure which is the cable and if this happens the whole network can shut down. Mesh-is a fully connected network in which each node is connected to each other. A fully connected network does not need to use switching or broadcasting. However its major disadvantage is that the number of connections grows with the number of nodes. It is extremely impractical for large networks. A two node network is technically a fully connected network. Tree-is a combination of a Bus and Star topology. It is arranged to look like a tree. The advantages are it is scalable...

Network Topology Course Objectives and Learning Outcomes In this assignment, you will describe the hierarchical star, bus, and ring network topologies. Assignment Requirements Chapter3 covered 3 main network topologies – hierarchical star, bus, and ring. Write a paragraph describing each topology. Discuss the reasons for using each, and any strengths/weaknesses each has. Submission Requirements Submit a 1-2 page Word document; double-spaced; Times New Roman 12 pt font. Cite all sources used. Section 1 In computer networking, topology refers to the layout of connected devices. Think of a topology as a network’s virtual shape or structure. This shape does not necessarily correspond to the actual physical layout of the devices on the network. For example, the computers on a home network may be arranged in a circle in a family room, but it would highly unlikely to find a ring topology there. Hierarchical Star Hierarchical star is also known as an extended star topology. Hierarchical or extended star topology is a star network with an additional networking device connected to the main networking device. Typically, a network...

...Unit 3. Assignment 1. Network Topology Paper In: Computers and Technology Hierarchical layout defines how the network topology is structured physically and logically. In physical topology all devices and components are placed in various locations depending on the layout. Logical topology is the flow of data throughout the layout. There are many variations of network topologies that can be implemented. The most common network topologies are star, bus, and ring. Star topology is setup with each host connected to a central hub with a point to point connection. All workstation and other devices are connected to the central hub or switch. That switch is the server and all devices connected to it are clients. All resources must be connected to a central device in order for it to be a star topology. Data that travels in the network passes through the central hub and causes it to act as a signal repeater. The advantages of a star topology are that it is easy to design and versatile in planting additional nodes. The major disadvantage of the star topology is that the hub becomes the single point of failure. Bus topology utilizes a single bus cable to connect each computer and the data from the source travels in both directions to all devices on the bus cable until it finds the specific client. Data is only accepted if the addresses matched up and if it doesn’t match, it’s simply ignored. The last computer connected to the bus needs to be terminated to prevent echoes in the network...

...Unit 3. Assignment 1. Network Topology Paper Hierarchical Star - When implementing a hierarchical, all computers are connected to a single, centrally located point. This central point is usually a hub of servers and switches located in the main equipment room and interconnected through the main cross- connection. All cabling used in a hierarchical star topology is run from the equipment outlets back to this central location. Bus Topology - The is the simplest network topology. Also known as a , in this topology all computers are connected to a contiguous cable or a cable joined together to make it contiguous. The signal in a bus topology travels to both ends of the cable. To keep the signal from bouncing back and forth along the cable, both ends of the cable in a bus topology must be terminated. A component called a , essentially nothing more than a resistor, is placed on both ends of the copper ( coax) cable. The terminator absorbs the signal and keeps it from ringing, which is also known as overshoot or resonance; this is referred to as. If either terminator is removed or if the cable is cut anywhere along its length, all computers on the bus will fail to communicate. Ring Topology - A requires that all computers be connected in a contiguous circle. The ring has no ends or hub. Each computer in the ring receives signals ( data) from its neighbor, repeats the signal, and passes it along to the next node in the ring. Because the signal has to pass through each computer...

...–week 5 Assignment Osman sulaiman Major event in networking from the 1960s to today: before or prior to 1960s, computers called mainframes were very large and expensive and use proprietary architectures that did not support cross platform communication. In 1960s, computer technology began to transform our social, economic, and governmental infrastructures. Data in paper form were being captured electronically as binary digits understandable to computers and the process is call digitization. Purpose of protocols: Is for computer and the network they use to understand and work with each other and it set the rules that determine how device communicate, Topologies Bus: in the bus topology system is connected in a line and when a packet is sent in a bus topology, there is no intermediary to determine who the packet should to, and every packet that is sent in a bus topology is receive by all system on the network. Ring: in the ring topology, the system is connected to its respective neighbor forming a ring. Star: in star topology, the system is connected to a central device, when one system goes down, it does not bring the rest of the network down. Mesh: in the mesh topology, every system is connected to every other system with a high availability. Bits and Bytes: A bit is a binary digit, the smallest increment of data on a computer. A bit can hold only one of two values: 0 or 1, corresponding to the electrical values of off or on, respectively. A byte is a unit of data...

...Performance in Wavelength-Routed Networks Laxman H. Sahasrabuddhe and Biswanath Mukherjee University of California, Davis We introduce the concept o f a light-tree in a wavelength-routed optical network. A light-tree is a point-to-multipoint generalizat i o n o f a lightpath. A lightpath is a point-to-point all-optical wavelength channel connecti n g a t r a n s m i t t e r a t a s o u r c e n o d e t o a receiver a t a d e s t i n a t i o n n o d e . L i g h t p a t h communication can significantly reduce the number o f hops (or lightpaths) a packet has t o traverse; and this reduction can, in turn, significantly improve t h e network’s t h r o u g h p u t . We extend the lightpath concept by incorporating an optical multicasting capability at the r o u t i n g nodes i n order t o increase t h e logical connectivity o f t h e n e t w o r k a n d f u r t h e r decrease its hop distance.

Company Background The company is a division of a Fortune 500 manufacturer of packaging material. This packaging material is used in cookie bags, cigarette cartons, cereal boxes, ice cream containers, and just about every conceivable food-product package. Customers purchase product based on weight (cents per pound or dollars and cents per pound). Additional charges that might be billed to the customer include special packaging charges, storage charges (if the customer requests that product be stored at a public storage facility), and shipping charges (if a contract carrier is utilized to deliver product to the customer). The product is marketed to an existing customer base through an internal sales force that reports directly to the Field Sales Force Manager. The Field Sales Force Manager in turn reports to the Vice President of Marketing and Sales. The combined charter of the marketing department and the sales force team is to maintain and expand product sales to existing customers and develop new sales with existing customers and prospect and develop new customers. The Vice President of Marketing reports to the General Manager of the division, who is an executive VP reporting to the parent company’s chief operations officer or president.

...A Distributed Joint Channel-Assignment, Scheduling and Routing Algorithm for Multi-Channel Ad Hoc Wireless Networks Xiaojun Lin and Shahzada Rasool School of Electrical and Computer Engineering, Purdue University West Lafayette, IN 47907, U.S.A. {linx,srasool}@ecn.purdue.edu Abstract— The capacity of ad hoc wireless networks can be substantially increased by equipping each network node with multiple radio interfaces that can operate on multiple non-overlapping channels. However, new scheduling, channelassignment, and routing algorithms are required to fully utilize the increased bandwidth in multi-channel multi-radio ad hoc networks. In this paper, we develop a fully distributed algorithm that jointly solves the channel-assignment, scheduling and routing problem. Our algorithm is an online algorithm, i.e., it does not require prior information on the offered load to the network, and can adapt automatically to the changes in the network topology and offered load. We show that our algorithm is provably efficient. That is, even compared with the optimal centralized and offline algorithm, our proposed distributed algorithm can achieve a provable fraction of the maximum system capacity. Further, the achievable fraction that we can guarantee is larger than that of some other comparable algorithms in the literature. I. I NTRODUCTION Multi-channel multi-radio ad hoc wireless networks have recently received a substantial amount of interest, especially under...
