LAN Topologies Assignment

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.

I have been recently hired to upgrade a company’s current network. Currently this company has a 10BaseT network established (Regan, 2004). This client is stating that they need to increase the overall bandwidth to the network and is having collisions issues occurring within the network which is causing more latency within the network. My two primary recommendations to upgrade this network are to; first go from a 10BaseT network to a 100BaseTX network, and second replace any hub currently in use with a switch capable of 100BaseTX data transfer standards. Transferring from a 10BaseT to a 100BaseTX network will require the additional purchase of networking devices but will increase the overall bandwidth from 10 Mbps to 100 Mbps for each user in the network (Regan, Local area networks, 2004). By replacing the outdated hubs currently in use with switch will create a more specific collision domain (Regan, Local area networks, 2004) that if found when hubs are in use. With the use of hubs all the ports on the hub are part on a collision domain, so each computer connected on the hub can be effected by collision of data as it passes through the hub. When switches are use each port on the switch is its own collision domain and collision rarely occur. This upgraded network will allow the

Lan Topologies

...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 network...

It/240 Lan Topologies

...LAN Topologies It 240 Week 2 Assignment: LAN Topologies IT/240 Week 2 Assignment 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. Case project 2-3 * Physical versus logical topology: A physical topology defines how the devices on a particular network are physically connected; logical...

Networking

...Julie Cason Networking Essnls II March 5, 2012 WAN/LAN Description Assignment The first part of this assignment is to describe the infrastructure of a network. The infrastructure is the hardware that enables computers to communicate with each other. My infrastructure is based on a star topology and can go from a LAN to a WAN very easily. I will begin with the type of cable that will be used to wire and connect my network. The cable I will use will be an Ethernet, coax interface also known as 10-base-2.The computers are connected to make a chain (like a star) and the coaxial 50ohm cable connects each “T” to the “T” on the next computer. The next technology that I will use is a hub/router. The hub houses a separate connection to each computer on the network. Any data entering the hub on one of the cables connected to it is repeated out onto all other cables connected to the hub. From there, it is then sent through a server and gateway. The gateway is tied into the Active Directory of all the computers on the network. From the server/gateway, it then goes into a Main Switch. The switch examines each arriving data packet and finds the packet's destination address. It then only sends data out to the port associated with that address. This cuts out a lot of needless network traffic and thus is why it is so important to have on a network. Finally, on my network is a Bridge. All computers end up connecting to the same wire and so they have to wait for silence on the network before...

...ACTIVE DIRECTORY WORKING WITH SITES CLASS NOTES NT1330 MR. GRAHAM 10/14/13 Sites overview Sites in Active Directory® represent the physical structure, or topology, of your network. Active Directory uses topology information, stored as site and site link objects in the directory, to build the most efficient replication topology. You use Active Directory Sites and Services to define sites and site links. A site is a set of well-connected subnets. Sites differ from domains; sites represent the physical structure of your network, while domains represent the logical structure of your organization. Using sites Sites help facilitate several activities within Active Directory, including: * Replication. Active Directory balances the need for up-to-date directory information with the need for bandwidth optimization by replicating information within a site more frequently than between sites. You can also configure the relative cost of connectivity between sites to further optimize replication. * Authentication. Site information helps make authentication faster and more efficient. When a client logs on to a domain, it first searches its local site for a domain controller to authenticate against. By establishing multiple sites, you can ensure that clients authenticate against domain controllers nearest to them, reducing authentication latency and keeping traffic off WAN connections. * Active Directory-enabled services. Active Directory-enabled services can leverage site...
