Troubleshooting Evco Insurance Network sample essay
The network manager himself not keeping track of the growth of the network , coupled with the return of an unspecified number of computers from storage back into the network, are conditions that would encourage the network congestion currently experienced by Evco Insurance. This is further confirmed by the fact that the worst network congestion occurs where the network has experienced the most expansion in the last six months: the Marketing department. Several causes come to mind, with the presentation of the scenario for Evco Insurance.
The first cause that comes to mind is in regards to the computers pulled out of storage. It is possible that since the computers were pulled out of storage, the configuration of the TCP/IP settings may have conflicted with newer additions to the network. This would affect the computers within the marketing department, since these particular computers were deployed there, and any other computers that share the same settings.
This would explain the some of the causes of the network congestion and the solution would be to correct or reconfigure the settings on the affected computers. This is a basic error, however, and would mostly affect only the individual computers that have conflicting settings and would not be the most probable cause, though it may contribute to the congestion.
Related to the first possible cause is the possibility that there are hardware errors that were unchecked when the computers were assigned to the new marketing personnel. A particular concern is the network cards of those computers taken from storage. One such error causes the network card to continuously transmit junk data into the network, flooding the network with unnecessary data and slowing down connectivity; in which case even just one such computer can cause the whole network to slow down.
Actual settings of network adapters and switch ports may also have conflicting settings. Both these hardware /settings errors can contribute to the network slowdown in the Marketing department, and both can be located using a combination of actually checking each computer and checking how far along the network a command or ping can travel.
Another possibility, but not the last possible cause, is the actual physical cable connections of the Network. A 100BASE-TX can have up to 100 meters of twisted copper cable per segment length, which must be rated at least category 5.
While it is possible that the network itself has been poorly maintained, and that individual cables within the physical network are causing the error, it may be more likely that there are problems or errors in the physical connections recently added to the network, since the problem of slow connectivity was experienced after the addition to the network. Ranging from poorly-maintained cables, using the wrong category of cables, or even the correct type of cable connected or the incorrect crimping of the cable can lead to network slowdown.
Any of these three, or perhaps none of them, could be the cause for the network slowdown experienced in the Marketing department of Evco Insurance. There could be other reasons for the problem, though these are the three possible causes that immediately came to my mind.
