Rough Draft
Reform of the Campus Network
The campus network has many problems and due to these problems it is plagued with down time. Some of the problems are due to the lack of equipment and some is due to the fact of outdated protocols and operating systems. The current network is established with multiple points of failure. The campus is also using the 2.4 Ghz frequency and this frequency can be used up by any piece of electronic equipment that uses this frequency.
The design of the network also has a lot to be desired. There are many points in the design that disperse the work load but at the point of the internet it has one point of failure. To resolve this problem there needs to be multiple exit points throughout the campus network. This allows for one piece of equipment to be brought down for maintenance while the other takes care of all routing of traffic. There should also be a backup to the backup this is because if during the maintenance there is a failure the backups backup can take over. This also goes to a good rule of thumb that most network engineers go by and that is for every link there should be two backups.
As for the lack of equipment the campus doesn’t have enough access points. It isn’t that they do not own enough of them it is that they do not use them efficiently. The campus should have an overlap of fifteen percent in the wireless range. They do have this but the downfall is where they got there information. The technical briefs for the equipment give a general range of use but does not account for line of sight issues. This could be fixed by the rearrangement of equipment and instead of using the technical briefs they use field studies and visually see what could be causing interference in the line of sight.
Another problem with the network is that the frequency used by wireless networks is 2.4 Ghz. This is only a problem because there is only eleven channels that this uses and they can be used up by the use of too many 2.4Ghz electronics. The solution for this is not easy and could be controversial. There is no way to change the wireless frequency so to fix this problem you have to remove as many 2.4Ghz electronic devices as possible. You could do this by prohibiting phones and other devices that work on this frequency.
One of my most dreaded problems is the outdated systems. The system that causes me the most grief is the ORCA accounts. This system is a Linux based system that seems to not have ever been updated. This is a very simple fix all that is required is an update of the operating system. This can be done at midnight if need be but it should be done.
The final problem that I have noticed is that there is no kind of authentication. This can cause a problem in that if students using the network are trying to buy stuff from any website their credit card and identity is out in the open. This means that anyone can grab their credit card number or social security number or any other vital information. This is the worse of the problems with the network because this can cause life long problems for students, such as bad credit.
