ACME Network Design

As a network consultant hired by Acme Manufacturing, the company has asked Team A to develop a new networking design for Acme’s expanding business. The description below describes the key steps involved in developing a WAN for Acme Manufacturing. The company has six different buildings in six different locations throughout the world that needs to be networked collectively. All the remote locations need to communicate effectively with the main headquarters that is in Atlanta, Georgia. The two buildings that house the headquarters are located across from each ...view middle of the document...
VOIP (Voice over Internet Protocol) is a much newer concept. VOIP can connect to interoffice users as well, but also office users across the world. As long as the offices are interconnect in some fashion like VPN (virtual private network). VOIP is also fully featured: Voice mail, Caller ID, Programmable phones, Extensions, Hold Music, and etc. VOIP is not line specific, it is device specific. This means that you can take a VOIP phone and move it from office to office without changing anything. Of course the phone would have to be on the same network, but no more punching down wires every time a line moves. Traditional phone service will not be needed since VOIP service through your Internet connection is much cheaper.
The problems with VOIP stem from its design. If Internet connection is lost, the VOIP service is lost as
well. So instead of just losing Internet, and still operating over the phone is no longer. Also just like PBX, VOIP phones are expensive. In older buildings VOIP may be a challenge because of wiring. Most buildings don't have enough network drops to run both phones and computers. VOIP also suffers if there is too much jitter or a slow connection. Therefore, QOS (Quality of Service) needs to be set, to ensure call quality.
Acme Manufacturing will have several sites across the globe, two in Atlanta, Georgia, one in Chicago, IL, Phoenix, AZ, New York, NY, and a Plant facility in China. Team A will be creating an Internetwork that will allow each facility to communicate directly and secure under each facilities LAN firewalls and protocols. Each site will have its own LAN for all its workstations and administrators to control data across the Internetwork. Acme Manufacturing's network will consist of an extranet to allow outside users such as customers, vendors, and suppliers to access information they need using the internet. Using DNS to allow users to easily remember the address of Acme's server, www.acmemanufacturing.com will be the DNS code name of the IP address of the main site of the network.
Each LAN will be coded with an IP address from the IEEE 802. The LAN will allow NAT to convert the IP addresses of each workstation as the packets are sent out. Each work station
will hide behind the LAN’s IP address. Routers will be located at each site and since Acme has the two in Atlanta they will have a bridge connecting the two LANs together. With the use of the Internet, the networks extranet will be able to be access from anywhere by simply using a web browser to search www.acmemanufacturing.com. On Acme’s web page there will be links for locations which information can be detailed and sent to the specific site. When data is to be sent from one site or another source, the sending user will connect via Internet to the routers of each site.
The router will send the data packet to its intended destination for delivery. Each workstation will have its own ID of the IP. So when data is to be sent to...
