...new network that will support the company’s needs for the next 3 years with few additional investments. Be sure to include the devices and type of network circuits you would use. You will need to make some assumptions, so be sure to document your assumptions and explain why you have designed the network in this way. Because we are considering the company present needs and over the next 3 years and not adding any addition investments, I would design the network using the traditional network design process. Computer Dynamics is centrally located in three adjacent five-story buildings, however there is no network connectivity amongst the buildings, which means we have to build a backbone to connect all three LANs. Before addressing the connectivity issues amongst the buildings, lets first look at the current topologies in each building; 2 Ethernet and token ring. I recommend going with Ethernet, it is a simpler topology, which has less room for errors. With 100 computers in each building I would recommend 100base-T Switched Ethernet LANs, in all three buildings. The type of circuit is dedicated point to point. In order to network the three building we will...

...select two backbone configurations and discuss which one you think is the better option for networks of today. Indicate why you think that planning an enterprise-level backbone can be such a challenging process. I think before going into details, we should understand what is backbone. After a lot of research, I came up this definition; a backbone is a means of connecting two or more LANs. It provides a transmission channel for packets being transmitted from one LAN to another. After connection to a backbone, a LAN may remain distinct or be merged with another. Backbone networks can be applied to a single building environment as well as to campus environments, where the backbone is used to connect LANs in different buildings. Parallel backbone: I think parallel back is the best worth it for any company. The additional cost of setting up a parallel backbone can be well worth the money. The design of this type of backbone consists of using two cables routed between the routers and switches. While there are additional initial costs of installing a parallel backbone, the benefits can quickly outweigh these costs. However if company wants to save some money, they can use distribute network. It consists of a number of connectivity devices connected to a series of central connectivity devices, such as hubs, switches, or routers, in a hierarchy. This kind of topology allows for simple expansion and limited capital outlay for growth, because more layers of devices can be added...

...Upon reviewing Kudler Fine Food network, it has been determined that a major network overhaul will need to be conducted to make sure that Kudler is brought up to speed with the latest technology. This is very important because if Kudler is unable to keep up with the technological advances then the company will fall behind. Making sure that Kudler is not only able to keep up with the advances with network systems it is also important to install the proper systems so that no money is wasted. What is meant by this is that if the improper systems and storage units are installed to only handle data over the next year this is only going to force Kudler to spend more money in upgrades in the future. This is why it is vital to install the proper systems that will provide room for future network expansion without having to waste money on unnecessary upgrades. The following is a list of problem areas with the Kudler network: • 56K modems provide slow connections speeds • Host systems at all site running Window 98 – over 10 years old • Windows NT servers are at the Delmar and Lajolla sites – over 10 years old. • The XLS servers at the Delmar and Lajolla sites are running Office 97 – over 15 years old. • The Novell Servers at the Delmar and Lajolla sites are running this was released in 1994. – over almost 20 years old. • All sites have a stand lone ups system that will need upgraded to provide a redundant power...

...Before one can begin to design a fiber optic cable plant, one needs to establish with the end user or network owner where the network will be built and what communications signals it will carry. Most contractors are more familiar with premises networks, where computer networks (LANs or local area networks) and security systems use structured cabling systems built around well-defined industry standards. Once the cabling exits a building, even for short links for example in a campus or metropolitan network, requirements for fiber and cable types change. Long distance links for telecommunications, CATV or utility networks have other, more stringent requirements, necessary to support longer high speed links, that must be considered. But while the contractor generally considers the cabling requirements first, the real design starts with the communications system requirements established by the end user. One must first look at the types of equipment required for the communications systems, the speed of the network and the distances to be covered before considering anything related to the cable plant. The communications equipment will determine if fiber is necessary or preferable and what type of fiber is required. Premises cable systems are designed to carry computer networks based on Ethernet which currently may operate at speeds from 10 megabits per second to 10 gigabits per second. Other systems may carry security systems with digital or analog video, perimeter alarms or entry systems...

...number of computers to form a Local Area Network(LAN), which consist of the physical and data link layer. During the 1980s, one of the first widely deployed Ethernet supported a theoretical data rate of 10Megabit per second(Mbps). Over the years through the advancement of technology, the maximum data rates were increased to 100Mbps to todays peak performing a whopping 1Terabit per second(Tbps), but only active in area of research. As workplaces slowly become a more computerised and network based, with the rise of emails and the internet, Ethernet has become more prevalent. Every computer that requires a connection to another or link to systems uses the Ethernet. The computers you use at home, in your office at work, in school that accesses the internet through the use of the Ethernet. Ethernet LANs consist of network nodes and interconnecting media. The network nodes fall into two major classes: Data terminal equipment (DTE) - Devices that are either the source or the destination of data frames. DTEs are typically devices such as PCs, workstations, file servers, or print servers that, as a group, are all often referred to as end stations. Data communication equipment (DCE) - intermediate network devices that receive and forward frames across the network. DCEs may be either standalone devices such as repeaters, network switches, and routers, or communications interface units such as interface cards and modems. LANs take on many topological configurations, but regardless...

New Office Eureka staff answers the phone and respond to requests entered on the Eureka! Website. Much of their work is spent on the phone and on computers searching on the Internet. They have just leased a new office building and are about to wire it. What media would you suggest they install in their office and why? ANSWER 1 I would suggest that Eureka installs (LAN) because it has information sharing and resource sharing. Company users would have access to the same data files, one computer sharing a hardware device for printing and internet connection or getting a software package with other computers on the network to save costs. Also all Eureka staff members would no longer have to upgrade all computers with package software. Q2 Speedy Package 1.) Assuming that each label is 1000 bytes long, how long does it take to transmit one label over the cell network, assuming that the cell phone network operates at 14 kbps (14,000 bits per second and that there are 8 bits in a byte)? (1000 bytes * 8 bits per byte) / 14000 bits per second = 0.571 seconds 2.) If Speedy were to upgrade to the new, faster digital phone network that transmits data at 114 Kbps (114,000 bits per second) how long would it take to transmit?

...Network Design Project Cecil Ruis NTC/362 August 6, 2013 Ron Inmon Kudler Fine Foods (KFF) is a small specialized company that deals in fine foods, wines and other related items for the discerning customer. Presently the company uses a dedicated T3 line to connect their La Jolla, Del Mar and Encinitas stores together with La Jolla being the site for the central server. The company incorporates a Bus Topology for a three locations. Bus networks use a common backbone to connect all devices. This is done with a single cable (backbone) that functions as a common communication link that all devices either tap into or attach to individually. Below is an example of a Bus Topology. Ethernet bus topology is considered the easiest to install and maintain because of its simplicity. Kudler uses a 100Base ThickNet cable for its backbone. The Bus Topology is very effective when connecting fewer than 15 components at a time. This is an ideal set-up for the company because all three locations have less than 15 connections per site. Each location has the same configurations which consist of six computers, one Point of Sales (POS) server, POS terminals, blade server (for all communications, e-mail, storage and Web), one printer, six Voice Over Internet Protocol (VOIP) phones and an APC Smart Uninterrupted Power Supply (UPS). The biggest downside to this system is that if anything happens to the backbone cable the entire system goes down. The plan for Kudler is to incorporate a...

...servicing the local area since 1975. Recently, The Chief Executive Officer (CEO) of Patton-Fuller Community Hospital expressed the desire to design an upgrade to the current network architecture. This design will include upgrades to hardware components and software components. This proposal will discuss and summarize the current network structure, propose an upgrade design to meet future challenges while addressing network security and compliance; more specifically, the transfer and confidentiality of patient records information. Patton Fuller Community Hospital – Current Network The current networking architecture of the Patton-Fuller Community Hospital can be broken down into two major sections. Today the two major backbones of the network include a 1000 Base T using CAT6 cable which provides network access to many administrative and operational areas of the facility. Executive management, Human Resources, Operations, Facilities, Finance, as well as the IT data center are all connected directly to this side of the network backbone. The hospital side is connected via 1000 Base F which uses fiber optics to ensure the very highest speed data transmission as well as protection from RF and other possible interference from hospital and lab equipment in use throughout this area. (Apollo Group, Inc., 2011) Bringing the two major backbones together one finds a Network bridge which seamlessly combines the two different network technologies to a unified bridge point.

Broadcast storms can be mitigated by increasing the number of broadcast domains, thus reducing their size. G.VLANs makes it easier for IT staff to configure new logical groups, because the VLANs all belong to the same broadcast domain. 2. What are some drawbacks of implementing VLANs within a network? •Usable bandwidth is shared among all the devices connected to the LAN •ALL devices connected within a LAN can hear ALL the packets irrespective of whether the packet is meant for that device or not. It is possible for some unscrupulous node listening to data packets not meant for that. •Suppose, your organization has different departments. Using a traditional LAN, when any changes take place within the organization, physical cables and devices need to be moved to reorganize the LAN infrastructure. •A LAN cannot extend beyond its physical boundary across a WAN as in VLANs. Management is complex Possible problems in interoperability A VLAN cannot forward traffic to another VLAN (need a router to communicate 802.1D Spanning Tree Protocol (STP) has a drawback of slow convergence. 3.

...Structure of WAN After much deliberation it has been decided that all ABC Company’s (ABC) main design centers in: San Francisco, Detroit, Paris, Tokyo and Sao Paulo and sales offices in: Washington, Indianapolis, Tampa and Liverpool, will each have their own Local Area Network (LAN) setup. These LAN’s will be designed to best facilitate their intranet needs and will have the inclusion of internet access. Each site will include switches and routers with other networked devices and will be designed off Star topology. The Star Topology is a common network configuration in which workstations and other network devices connect to a single point called the hub. (Exforsys, 2008) We will be installing Fiber optic cabling in all the main building design centers including San Francisco, Detroit, Paris, Tokyo, and Sao Paulo. The rest of the sales offices be taken into consideration since there are plans of opening other sale offices as the business continues to grow. The fiber optic will run from the backbone cabling, vertical cabling, and horizontal cabling. It will run to the telecommunication closet connecting to the switches. The fiber optic cabling will help provide the necessary speed for all the workstations and expansion for future growth. The connections from device to device will be done through a Layer 3 switches. A layer 3 switch is a high performance device that differs very little from routers. The layer 3 switch has the same IP routing table for lookups and it forms...
