Technology Framework Design : Digital Edge Manufacturing Network Infrastructure Plan

Great Essays
Technology Framework Design
In this section, we combine the user domain needs described in Part 1 of this proposal, the physical framework requirements described in Part 2, and the technology selections described in Part 3 to create the final Digital Edge Manufacturing network infrastructure proposal.
Choosing the Cabling Used in the Network
We considered infrastructure costs, speed, and reliability for cabling and adaptors. Our network employed hybrid type of network sine we use Ethernet cable, Wi-Fi and fiber optic as our media.
Ethernet Technology
The Ethernet technology was mostly used in the LAN because;
1. We used Ethernet speed of 10mbps for areas in the LAN that required higher bandwidth
2. Our campus network model supports dual links between each distribution layer routers and case switches. We are there able to load balance the aggregate traffic from multiple access switches across the links.
3. Giganet Ethernet will be used between switches but Fiber will be used between backbone switches.
In this network, we used straight- through cabling to link the following devices
1. Switch to router
2. Switch to PC or server
3. Hub to PC or server.
Cross-over technology was used to connect these devices
1. Switch to hub
2. Hub to hub
3. Router to router
4. Pc to pc.
Wi-Fi Technology
This was used to connect the electronic devices used in the network using the 2.4-gigahertz. Our Wi-Fi network is based on the IEEE 802.11 b/g standards, which is the most commonly used standard. We have added Wi-Fi access points in our network to give easier access to corporate data and services. Most of the devices in this network, for example the personal computers, smartphones, digital cameras, tablets and digital audio players connected using the Wi-Fi technology. The hotspot will be in the range of 20 meters (66 feet) indoors and a greater range outside. To improve security, the Wi-Fi uses various built-in WEP encryption technologies to prevent attacks from the hackers who may want to get access to the corporate data. We will continuously assess our Wi-Fi network in each and every site, analyze alternative security techniques, and suggest ways to secure our network. Fiber Optic Technology Fiber will be used majorly to connect to different departments/ buildings in each and every site. It will be used for backbone cabling since it can transmit over longer distances and at higher bandwidths than both the Wi-Fi and Ethernet cables. It greatly reduces the data loss, and immune to electromagnetic interference. The WAN fiber will be used to connect to regions/ sites where the satellite signals may be blocked by the mountains. This is usually done over leased WAN fiber lines as opposed to the LAN fiber lines that are always privately. Vendor Selection As team six searched for various vendors, we found that most vendors could install network equipment and set up basic networks, but we wanted a vendor who could not only focus on installing a network; but securing and fine tuning that network to provide the highest level of security, stability, and reliability. The services we wanted are listed below. 1. Network installation 2. Onsite support 3. Remote monitoring and management 4. Reengineering of existing and Wide Area Networks 5. Network troubleshooting and problem resolution 6. Router support 7. Business process reengineering 8. Project management 9. Support Agreements 10.

    I would install the Star topology which is the most common type of network topology that is used in offices. Star topology is the best since each node is connected by more than one link basically two connection to reach a node. The speed of most star configurations is hundred megabits of data per second with gigabit hub or switches and NIC cards speeds can be at one thousand megabits per second. In a star topology is possible to have all the important data back ups on the hub in a private folder so if the computers fails, the employees can still use the data using the next computer in the network and accessing the backup files on the hub. If the hub adds a device like a printer all the other computers on the network can access the new device by simple accessing the hub.…

    The Internet was originally called the ARPANET, and in order to enhance the ARPANET to be enable may different types of computer networks to all communicate with each other, an open source protocol needed to be created, hence the development of TCP/IP. TCP/IP improved communications throughout the network and allowed all computers to easily communicate with one another. Another technology that helped expand the ARPANET to more users in a specific location was the development of the Ethernet. Ethernet is a coaxial cable that is still used today in many local area networks. Ethernet is highly effective in moving data from one computer to another at high speeds.…
