...LAN Topologies LAN Topologies Ashley Jones University of Phoenix Case Project 2-1 This Case Project explains a network comprised of 50 computers that are connected to 10 Mbps hubs. It goes on to explain the collisions that are occurring when multiple stations send data simultaneously. This description indicates the network is using a logical bus topology because of the 10 Mbps hubs it utilizes. In addition, they are experiencing collisions; in a logical bus topology, data transmitted on the network is viewable by other nodes. The physical topology of this network seems to be an extended star. Since a multiport repeater/hub can have up to 24 ports, they can lay this network out in many different ways. If there is enough office space, they could set up 5 different offices of 10 stations. Each set of 10 would be connected to one 10 Mbps hub and form a physical star. Each of these hubs can be connected to a central hub that is used to extend the network. Case Project 2-2 This Case Project advises of a network that has 200 workstations and four servers connected by multiple switches. The network incorporates a physical star topology because all of its devices come together at a central location. More specifically, this exended star topology allows about 20 workstations to connect to one switch. This setup is repeated multiple times, all with 20 workstations connected. Another switch sits in the “center” of this setup and attaches to one of the switch......

...LAN Topologies IT240 10/14/12 1. Case Project 2-1 With a network of 50 computers I will use the Ring Topology to upgrade this network. With this type of topology all the devices are connecting in a loop form and the information travels in one direction, thus avoiding collisions. Here the cabling doesn’t terminate, it continually goes from one device to another till it gets back to the original device. It is also easier to manage the network since all the information is passed around the ring in the same direction. 2. Case project 2-2 With that many computer and four servers, I will use an Extended Star Topology. As pointed out in the case project that there are a few switches available here, I will use a central switch and connect the rest of the available switches to it and connect the 200 PC’s to those switches. Switches are good for determining each individual packet’s destination and ensuring that they are delivered to the right device. Note Even though they might have two different uses in some cases, the hubs in my diagram represent the switches. 3. Case project 2-3 * Physical versus logical topology: A physical topology defines how the devices on a particular network are physically connected; logical on the contrast tells us how the systems on the...

Network Topology

...Hierarchical star topology is where all computers are connected to a single, centrally located point. The central point is usually a hub of servers and switches located in the main equipment room. If there is a problem with the central hub then the network will not be able to work. It can bring the whole system down. By having everything centralize, it makes troubleshooting and reconfiguration simpler. It is usually a home networks that uses a hub or switch. Star Bus topology is the simplest of the network topologies. All of the nodes are connected to the single cable. The central cable is the backbone of the network. All of the workstations communicate with each other through the bus. The advantage to a bus topology is that it is easy to set up and is cost less than other topologies. It uses less cable due to the restriction of the length of cable. The disadvantages are the limit amount of devices to be connected. It is harder to troubleshoot when there is a problem. Maintenance will cost more in the long run. Bus Ring Topology is where all of the computers are connected together that it creates a closed loop. Each of the workstation can communicate with its neighbor by two other components. The data travels in one direction in the network. The advantage of ring topology is all of the traffic flows in one direction at high speed. Each computer will have equal access to resources. The disadvantages are that it can be slower than a star topology and......

...Network Topologies Mesh topology, in a mesh network devices are connected with many redundant interconnections between network nodes. Every node has a connection to every other node in the network. There are two types of mesh topologies. Full mesh topology occurs when every node has the circuit connecting to every other node in the network. Full mesh is very expensive to implement but yields the greatest amount of redundancy, so in the event that one of those nodes fails; network traffic can be directed to any of the other nodes. Full match is usually reserved for backbone networks. Partial mesh topology is less expensive to implement and yields less redundancy than. With partial mash some nods are organized in a full mesh team but others are only connected to one or two in the network. Partial mashed apology is commonly found in peripheral networks connected to a full mesh backbone. Bus Topology; the bus apology is the simplest network topology. Also known as linear bus, and all this topology all computers are connected to a contiguous cable or a cable joined together to make it contiguous. Ethernet is the common example of a bus topology. Each computer determines when the network is not busy and transmits data as needed. Computers in a bus apology listen only for transmission from other computers; they do not repeat or forward the transmission on the other computers. The signal in a bus topology travels to both ends of the cable. To keep the signal from bouncing back and......

Topology Paper

...In a hierarchical star topology, all of the computers within the network are connected to a single, centrally located point which is usually a hub of servers and switches located in the main equipment room and interconnected through the main cross-connection. This particular topology is typically found in commercial buildings where there is a horizontal cross-connection with a workgroup switch located in a telecommunications room that allows backbone cabling to interconnect with horizontal cabling. The hierarchical star topology is now almost universal and the easiest of the three networking architectures to cable. If a single node on the star fails or the cable to that node fails, then only that single node fails. However, if the hub fails, then the entire star fails. In a bus topology, it is considered the simplest network topology to establish. It is also known as the linear bus, which means that all computers are connected to contiguous cable or a cable joined together to make it contiguous. The strength of a bus topology is that companies find the lack of excess wiring inexpensive and beneficial for constant workflow and efficient business. The downside to this model is that if that single cable is damaged or down for any period of time, then the entire company is down for business which can cause catastrophic results for companies that rely on computing as their main means of business. A ring topology requires that all computers be connected in a contiguous circle.......

...Network Topologies. Hierarchical Star. the star network is one of the most popular network topology. In this network, all the nodes are connected individually to one common hub. In other words, it is a network topology wherein transmission stations are connected to the central node in such a manner that the design resembles the shape of a star. Basically, the star topology design is quite similar to a bicycle wheel with spokes radiating from the center. Advantages and Disadvantages It is very easy to install and manage star network topology as it is the simplest of the lot when it comes to functionality. It is easy to troubleshoot this network type as all computers are dependent on the central hub which invariably means that any problem which leaves the network inoperable can be traced to the central hub. In star topology, the data packets don't have to make their way through various nodes which makes sure that the data transfer is fast. The foremost problem with star network topology is the fact that it is highly dependent on the functioning of central hub. The size of the network is dependent on how many connections can be made to the hub. This network type requires more cable as compared to linear bus topology which means the expenses incurred would be relatively high. The performance of the entire network is directly dependent on the performance of the hub. If the server is slow, it will cause the entire network to slow down. Bus Topology Bus Topology is the......

...Aybar IT/240 LAN Topologies Scott Perales April 27, 2014 Case 2-1 I would recommend the use of a central server which will ease up the process of controlling the incoming and outgoing data transmission. The central server will help the network not get overloaded with the amount of data packets being received and sent. In relation with the Hubs, it will be beneficiary to update them to be able to hubs with the capacity of 1,000 Mbps. This will also help with the overall network performance. Case 2-2 In this case, I will replace the switches and install routers instead. Routers have a better capability in joining together multiple LAN networks with WAN. Routers serves as a median destination for the network traffic. The routers with these workstations will be able to receive, analyzed the source and potential target, and where every packet will need to be sent to. Switches in this scenario, are not able to separate the broadcast domain like the router could; switches are only able to separate the collision in the domain. A network with only switches (hubs) must instead designate one computer as the gateway to the Internet, and that device must possess two network adapters for sharing, one for the home LAN and one for the Internet WAN. (Mitchell, 2014).  Case 2-3 Logical/physical topology: A logical topology is the......

Communication Topology

...TOPOLOGY: Local Area Networks (Hybrid Topology) A conceptual diagram of a local area network with the features of Bus topology combined with Ring topology. A design that utilizes a single length of cable, also known as the medium, with directly attached LAN stations. All stations share this cable segment. Every station on this segment sees transmissions from every other station on the cable segment; this is known as a broadcast medium. The LAN attachment stations are definite endpoints to the cable segment and are known as bus network termination points. This single cable segment lends itself to being a single point of failure. If the cable is broken, no LAN station will have connectivity or the ability to transmit and receive. For the Ring connection, all stations in a ring topology are considered repeaters and are enclosed in a loop. Ring topology has no end points. The repeater in this case is a function of the LAN-attached station’s network interface card (NIC). Because each NIC in a LAN-attached station is a repeater, each LAN station will repeat any signal that is on the network, regardless of whether it is destined for that particular station. If a LAN-attached station’s NIC fails to perform this repeater function, the entire network could come down. The NIC controller is capable of recognizing and handling the defective repeater and can pull itself off the ring, allowing the ring to stabilize and continue operating.

Topologies in Ict

...ICT PROJECT ON TOPOLOGIES. STAR TOPOLOGY. In the star network topology, there is a central computer or server to which all the workstations are directly connected. Every workstation is indirectly connected to every other through the central computer. Star networks are one of the most common computer network topologies. ADVANTAGES :- * Better performance: star topology prevents the passing of data packets through an excessive number of nodes. At most, 3 devices and 2 links are involved in any communication between any two devices. * Easy to detect faults and to remove parts. * Installation and configuration is easy since every one device only requires a link and one input/output port to connect it to any other device(s). DISADVANTAGES :- * High dependence of the system on the functioning of the central hub. Failure of the central hub renders the network inoperable. * It can be expensive to purchase. * Star topology requires a large amount of cable to be connected. RING TOPOLOGY. In the ring network topology, the workstations are connected in a closed loop configuration. Adjacent pairs of workstations are directly connected. Other pairs of workstations are indirectly connected, the data passing through one or more intermediate nodes. Data travel from node to node, with each node along the way handling every packet. Because a ring topology provides only one pathway between any two nodes, ring networks may be disrupted by the failure......

...LAN Topologies Jason Smith IT/240 September 7 2014 TAMMY FLEMONS LAN Topologies Case Project 2-1 You have been hired to upgrade a network of 50 computers currently connected to 10 Mbps hubs. This long-overdue upgrade is necessary because of poor network response time caused by a lot of collisions occurring during long file transfers between clients and servers. How do you recommend upgrading this network? What interconnecting devices will you use, and what benefit will you get from using these devices? Write a short memo describing the upgrade and, if possible, include a drawing of the new network. This system ought to have a central server that can control approaching and cordial transmissions. A central server would prevent the whole system from being hindered due to information parcels being sent and acquired. What's more, the center points ought to be moved up to handle 1000 Mbps. The following is a sample of what a littler variant would look like. I think I would use the physical star topology for this setup. Case Project 2-2 Two hundred workstations and four servers on a single LAN are connected by a number of switches.

Network Topology

...MADONDO K.T R159819H HBBSP Information processing; Network Topologies Network topology is the arrangement of various elements (links, nodes etc). It is essentially the topological structure of a network and can be depicted physically or logically. Physical topology being the configuration of cables, computers and other peripherals whilst logical topology illustrates how data flows within a network regardless of its physical design. Types of network topologies include bus, star, mesh and ring topologies. Bus networks use a common backbone to connect all devices. A single cable, the backbone acts as a shared communication medium that devices tap into with an interface connector. A device wanting to communicate with another device on the network sends a broadcast message onto the wire that all devices see but only the intended recipient actually accepts and processes the message. The table below summarizes advantages and disadvantages of bus topology. Advantages Disadvantages      It is cheap , easy to handle and implement Requires less cable It is best suited for small networks  The cable length is limited It can only perform well for a limited number of nodes Network effectively becomes unusable if backbone cable fails In a ring network, every device has exactly two neighbors for communication purposes. All messages travel through a ring in the same direction either clockwise or counterclockwise. To implement a ring network we use Token Ring technology. A token...

...NETWORK TOPOLOGIES | Mukesh RaoDepartment of Computer Sc. & Engg. School of Engineering and Technology Sharda University, Gr. Noida UP, INDIA Mysteriousrao@gmail.comApril 14, 2015 | Abstract In recent days for computing, distributed computer systems have become very important and popular issue. It delivers high end performance at a low cost. Computers are connected by means of a communication network in a distributed computing environment which is arranged in a geometrical shape called network topology. In the present paper a detailed study and analysis on network topologies is presented. Definitions of Physical and Logical Topologies are also provided. Introduction Network Topology is the study of the arrangement or mapping of the elements (links, nodes, etc.) of a network interconnection between the nodes. Topologies can be physical or logical. Physical Topology means the physical design of a network including the devices, location and cable installation. Logical Topology refers to the fact that how data actually transfers in a network as opposed to its design. Some of the most common network topologies are: Physical Topology Physical Network Topology emphasizes the hardware associated with the system including workstations, remote terminals, servers, and the associated wiring between assets. Physical topology defines how the systems are physically connected. It means the arrangement of devices on a computer network through the actual cables......

...LAN Topologies Lord Bones IT240 Jan 01, University of Phoenix - AXIA College LAN Topologies With this assignment I will discuss some topologies of a LAN as requested by questions 11, 12, and 13, chapter three from the textbook Local Area Networks. A “LAN (Local Area Network) topology is the appearance or layout of a network” (Regan, 2006). There are two forms of topologies of a network, namely, the physical- and logical topology with each its own types of topologies. The physical topology is what someone can see with his or her own eyes, i.e. a workstation, servers, cables, etc. while the logical topology is the dataflow of the network, how the data is moving from one point to another (Regan, 2006). In the following I will describe two physical topology types and one logical topology type, following the scenarios in the question’s mentioned above. In the first scenario there are four servers in the network with no hub present. The first (A) server is connected to the second (B), third (C), and the fourth (D). The second is connected to the third and fourth, while the third is connected to the fourth. (See figure 1.) This type of physical topology is called a Mesh Topology. A Mesh Topology is a topology where “every computer is linked to every other computer” (Regan, 2006). With this type of topology there is no hub or a similar device present. Also this type is difficult to install and certainly when it has to be reconfigured when a new computer is added to the......

...Bus Topology is used for small and simple networks. Bus topology connects all computers in a linear shape with a backbone to connect all computers. A single cable is used to connect all computers devices with interface connector. A single device send message towards other devices attached with it but only intentional recipient accept and process the message. A central device like hub, router and switch is used to connect all computers in Star Topology. The functionality of connected devices is entirely different from each other in star topology because it may be Shielded Twisted Pair (STP) cable or UTP cabled. The STP stands for shielded twisted pair cable and UTP stands for unshielded pair cable. It is a most usable topology in local area network from all over the world. In Ring Topology all computers are situated in the form of a ring and each computer connected within two neighbor’s computer by the means of communication. In Ring topology all computers communicate with each other clockwise or counter-clockwise. The use of ring topology is increasing day by day because a network can be easily implemented in home, office, building, and school. Ring topology has some benefits such as equal access to everyone, transformation of data at very high speed but has disadvantages like the fault in any cable or wire may cause of failure network. Mesh Topology designed on the concept of Router because its work depends on router. When a user send a message to any other user, then......
