Network Design Proposal
This paper will provide the recommendations for a network that will allow the connection of 50 different remote locations. Half of the remote locations will be required to connect with central headquarters 6 to 8 hours a day and send large files back and forth which consist of date, graphics and product design information including blueprints. The other 25 locations are sales offices and connect at the end of the day to upload daily/other periodic reports that total less than 5 megabytes of data.
With the given research I have gathered, I recommend the following:
LAN
Each of the 50 LAN within the remote locations does not have a criteria within the question posed. A few things are taken as assumptions. The first assumption is that the 25 remote locations does not only need to have the ability to send files from to the central headquarters 6 to 8 hours a day but that it also needs the ability to send these files among themselves. The network requirements also states that the other 25 locations only needs to connect to the central headquarters at the end of the day and upload files less than 5 megabytes to the central site. The second assumption is that at no point the sales site could convert to a site that would require the ability to send videos and other large files to each other.
With these assumptions, I recommend the LAN to use an Ethernet protocol for the 25 sales sites. This protocol is the most widely used protocol as of today (Martin W. Murhammer, 1999). Ethernet is the most cost effective method to employ over the LAN network for the requirements given. Ethernet provides the equivalent to hitting a fly with a fly swatter, instead of using a mallet which would be done by using WAN protocols such as frame relay and ATM. Because this network would use a bus topology, we will use the access method of CSMA/CD to prevent packet lost (Martin W. Murhammer, 1999). This access method will allow computers to use the same transmission line and
