Lan Topologies Assignment Essay example

This is a network proposal to connect six computers and two printers. The purpose of the project is to ensure the six employees can be able to; share files electronically print to both laser printers access each other's calendars and share an Internet connection.

Swagger Distribution’s networking illustration is showing a wired networking system for the company. As the diagram shows, the companies system is most important in the computer room. This is where most of the company’s connection begins. The internet, which is the WAN (Wide Area Network) is the beginning to the LAN (Local Area Network). This starts with the WAN coming into the computer room’s T1 Demarcation Router. The T1 Demarcation Router is then connected to the Main Router which has a connection to the Firewall as well as the Ethernet Switch. The Ethernet Switch then has a Fiber Optic cable connecting to the warehouse Remote Ethernet Switch. This allows

The church required that the workstations be replaced as they are no longer supported by the hardware manufacturer. The workstations operating Windows XP can no longer receive a software patch and are no longer supported by Microsoft. These workstation are extremely vulnerable to attack. Wireless connectivity through the church campus was a requirement as the church was to be able to access information from multiple locations. Setting up hardware to maintain and secure all data and information. The sponsor liked our team’s suggestion to migrate them from a peer to peer network environment to a server domain environment. With all of these upgrades and updates, network security needed to be addressed so the installation and setup of a firewall became a requirement. The

The network consists hardware and software components and other components to keep the company safe. A common network that Jay’s company will need are routers, switches, firewalls, load balancers, SANs, and Domain Name System (DNS). The router and switches will allow the systems to communicate. Jay needs to ensure that the routers have spare capacity after the deployment to cope with projected growth and usage. The switches will connect to the system within the network. Both running at capacity tend to induce escalating bottlenecks. This will affect how long it takes for the clients to submit messages to the servers on different networks, Jay needs to make sure he is up to date with the router and switch because it can cost greatly if he does not.

Routers and switches will be utilized to route network signals to all areas of this large network. Telephony systems will be introduced to serve the VOIP located at each location to assist with communication needs. Wireless technologies will also be needed to assist with mobility and other devices such as printers, laptops, fax machines, etc. Lastly, a physical firewall will be enforced at each location to protect the network from internal and external intruders.

After reviewing the Kudler Fine Food network, a major network overhaul will need to bring the network up to par with the latest technology. If Kudler Fine Foods is not able to upgrade their systems then they will fall behind the technological curve and will not be able to compete with other companies. Kudler needs to do the upgrade not only to keep up with the advances with network systems but needs to install the proper systems to increase profits. If Kudler does not do constant upgrades then they will be forced to pay a larger amount for the larger upgrades in the future. It is vital to install the proper systems that will have the longevity and the capability for future network expansion without having to spend money on unnecessary upgrades.

The proposed network is designed to serve DesignIT which consist 56’x36’ office space, 4 cubicles, 1 office, 1 server room, 1 receptionist desk and 1 conference room.

So therefore, based off the information provided, I would recommend a packet switched architecture, or more specifically a Frame relay with a CIR 45 Mbps WAN service. Frame Relay is packet switched data link layer protocol that handles multiple virtual circuits using High-Level Data Link Control (HDLC) encapsulation between connected devices. (Cisco, 2005) In many cases, Frame Relay is more efficient than X.25 and generally less expensive than ATM. Also the data provided does not suggest that MegaCorp specifically has needs for the extensive QoS information that ATM provides that would enable the setting of very precise priorities among different types of transmissions such as high priority for voice and video and lower priority for email. If the company were a consulting firm with a high propensity for needs on bandwidth because of video conferencing or high bandwidth requiring applications then perhaps ATM architecture with a T1 or T3 WAN service might be more suitable. Even though MegaCorp is a large manufacturing firm recommending Ethernet services might prove to be too expensive of a proposal as well and thus causing us to lose the project. The cost associated to having each factory connected by fiber optic cables to the provider’s city wide MAN backbone plus the cost of the Ethernet switch might not be justified by the company’s bandwidth needs.

Main Building – will require 7 computer stations with the most recent version of Operating System to ensure compatibility and networking capabilities between each stations and the ability to communicate between the two locations. They will require three servers, one for web hosting, one for database management and one for emergency failure of any one server. These stations should be networked to communicate with one another for proper data connection especially in the event of any one computer station crashing. Each work station will need to be linked to each server for web hosting and data backup. The cabling used for inside the main building should be 100Base TX cat 5 UTP, for Wi-Fi and WLAN with guest access that is highly secure and reliable, we recommend a device that is capable of supporting up to 15 different users with 450 Mbps. There needs to be 4 printer services in this building. Printer 1 should have

Note to instructor: An alternate answer could be a single large LAN for the entire headquarters, interconnected via a WAN to the field offices.

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.

LAN Switch- A LAN Switch performs the same work as a hub except that, a switch does not broadcast packets to every computer in the network like hubs. All the computers and computer devices will be connected to the switch by Ethernet cables. The LAN Switch costs $150.

You work for a small, local telecommunications company. In five years, the company plans to undertake a major upgrade to its servers and other IT infrastructure.

Since one office is in the center of the WAN, it would be the most logical location for the main server headquarters. This main location would be home to six servers, two of them being print servers and the other four each hosting their own specific applications to all of the workstations in the network. The first of the four servers would hold the business management applications needed by any of the accountants or human resource teams. The second would hold the medical managing software that would hold all patient information, insurance, and bills that could be accessed from any of the 5 office locations in the network for both doctor and patient convenience. The third will be used to host a web server and the final system will be used as a domain controller that will manage the users and groups on the network.
