...company anticipates significant growth in network traffic. There is currently no network connection among the buildings, but this is one objective in building the new network. Describe the network you would recommend and how it would be configured with the goal of building a 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...

...devices you would recommend they purchase and explain why. Also describe the media utilized. Note, you are not required to detail the topology utilized, but thinking about this will help you to choose and justify your device choices. a. Describe what network device or devices are recommended for purpose for the given home network scenario(s). For a family who wishes to connect several devices to share and Internet connection and a Bluetooth wireless printer, I would recommend that family procure a wireless router, a modem, and a few CAT5e Ethernet cables. b. Explain the recommendations justifying why these would suit the needs for the network The family has several devices that need internet connectivity; the recommendations I made will make this happen. The modem connects to a wireless router, via plugging the broadband into the WAN port of the router, and the router will access the Internet through a unique IP address (assigned by the ISP). This will then provide local IP addresses for all of the devices connected to it, allowing the family to get Internet out to all of the devices (both wired and wireless). An advantage of having a wireless router is that it provides more safety, compared to connecting your broadband directly to your computer, because your computer's local IP addresses aren’t visible to the Internet, which means it's not visible to criminals or hackers. With all of this said, I would recommend to the family that the modem and wireless router be put into...

...subnet results give us a range of usable IP addresses, we have decided that the first range (192.168.0.1-192.168.63.254) will be dedicated to all of the networking/backbone equipment. The rest of the IP addresses will be distributed to their server farms and employee devices. Internet Access Their internet access will be provided by an ISP or internet service provider. They will need a dedicated fiber line running straight from the ISP’s datacenter to the company’s facility. This dedicated fiber line should have the maximum bandwidth possible, usually for commercial or hosting companies like Fiber Integrated Networking, ISP’s offer 10 Gbps lines. Network Components Router: For Fiber Integrated Networking we recommended Cisco 4000 series routers because they have higher performance than Cisco’s older generation routers, industry-leading threat defense, virtualization, and more.

...troubleshooting is simple because the devices are individually connected to a central device. So if a cable is broken or stops working on the device connected is impacted. Taking into account that speed and performance are key issue to consider I proposed network design will be based on a 1000BASTE-T. This structure will allow for speeds up to 1000 gigabits per second. Along with the faster speeds this will reduce the chance of any crosstalk while data is being transmitted on the media. With reduced chanced of crosstalk the data has less chance of being corrupted. Due to the lowered possibilities of crosstalk and corruption the integrity of the network is increased. Considering the network architecture and requirement of the network I would recommend using...

...corrupted. First I will talk about the equipment needed to make a small business network function, with minimal errors. Next I will explain the pros and cons to managing a small business network. Lastly I will talk about what I recommend for a small business network. To start the body off, I will be explaining what equipment is needed to start a small business network. First we have our routers and switches. Routers perform many functions, one of which is serving as a firewall. Computers have tens of thousands of ports, or "doors" as this essay will refer to them as. Without a firewall, all the doors on the computer are unlocked and available for anyone to use. Anyone could be your brother sending an email, or hacker from Indonesia using your computer to send SPAM. Firewall's will recognize all the doors your computer isn't using and lock them, so no one can use the doors, unless you know the password for the firewall. Routers also have various other functions, which may or may not be used by businesses; it all depends on your application. Switches take one internet connection and split it into many connections. Fore example, if you have a cable modem and you want six computers online, you will need to get six IP addresses from your ISP and use a switch to split the one incoming connection. An IP address is like a street address, one per computer or connection to the internet. Switches can also be used as device for connecting computers in a network. If you had seven computers...

...size over the next two years, but does not want a drastic overhaul. For this assignment I will hit 4 main topics. First I will describe what changes I would suggest for the current network type and explain why I am doing it. Second, I will describe why I would recommend upgrading to twisted pair cable from coax cable for all current and new client computers on the network. Third, I will discuss the possibility of implementing fiber optic cable in to the network. Finally, I will display research costs and analysis to facilitate an upgrade on the network. As above mentioned, the current network is 20 Windows peer-to-peer client computers utilizing the bus topology. Also important to note is the fact this company lacks an employee with an IT background, therefore they have been inclined to set up a simple peer-to-peer network due to its ease of configuration. Unfortunately for Ocper, if they want to effectively expand, they will need to change this network type, because a peer-to-peer network is not flexible. As the network grows, adding or changing important elements of the network may grow cumbersome. Additionally, the peer-to-peer network for this client is dire need of a centralized resource. I would highly recommend that...

This design includes the infrastructure for the corporate headquarters located in San Francisco, as well as the other design centers in Detroit, Paris, Tokyo, and Sao Paulo. We then follow up by explaining the infrastructure of the sales offices, which may not require as high grade of equipment as the design centers depending on its requirements. Finishing with the overview of the entire wide area network, connecting each site to the corporate headquarters which is where we will begin our design. The corporate office being the main headquarters will include many services such as file, print, email, directory, and application. These services will be separated onto at least two different servers due to the constant strain we may see from directory and email services. If necessary we will implement an application server as well to run any in-house programs the company may be familiar with. We also suggest the use of a database server dedicated to storing...

However, they have realized that their Internet connection is too slow. They have been using a dial-up BRI ISDN connection. They want to spend no more than $250 per month on an Internet connection (not including installation fees). They also need a transmission method with fairly good security and a guarantee of adequate throughput during the daytime hours. What solution can you recommend that will offer them the most throughput at this cost? I would recommend that they purchase a router and upgrade their internet connection to frame-relay PVC at 256 kbps, which would be giving them double the speed they currently have, plus with the...

...and can only be used for distances shorter than 2,000 feet. Several other disadvantage of a wired network such as the “need to run cables in difficult environments through walls, floors and ceilings. Cables need to be run from computer to computer and switch to switch. Process can be time consuming. Loose cables likely remain the single most common and annoying source of failure in a wired network.” (PACE University, n.d.) While a wireless network is a very useful and convenient networking device, however these types of networks a lot less secure and transmission speeds can suffer from outside interference. Although wireless networking is a lot more mobile than wired networking the range of the network is usually 150- 300 indoors and up to 1000 feet outdoors depending on the terrain. The cost for wired networking has become rather inexpensive. Ethernet cables, hubs and switches are very inexpensive. Broadband routers cost more, but these are optional components of a wired network, and their higher cost is offset by the benefit of easier installation and built-in security features. The primary parts of a wired network are the cables, network adapters, and routers. Wired LANs offer superior performance. The tools needed would be a Crimping tool, Punch Down tool, Cable cutters, Cable strippers, and a Cable tester. A traditional Ethernet connection offers only 10 Mbps bandwidth, but 100 Mbps Fast Ethernet technology...
