that dumbass being me, of course.
I am currently doing an IT traineeship at a Secondary College.
So, at the moment I have to do these TAFE excersises associated with the traineeship. I breezed through the first two but now i'm onto the third one and the last question/excersise is a prick....
ICAITS032B/03
it says:
--Monitor Network Performance--
Dicuss the importance of baseline information in regards to network performance.
what the is baseline information and what the hell does the above sentence mean?
pleeeeeeeease help me...
I'm dyin' here :( |

| the baseline may be a benchmark of network throughput, which you later compare to the network performance during peak traffic times, backup times, off-peak times, etc? |

Baseline information is a generic term, not just applied to networking. Simply, it means to find the "normal" level of traffic on the network, from which you can compare traffic after any changes are made.
It's important to get a baseline, otherwise you have no idea whether making a change has actually improved thing, or made them worse.
Here endeth the lesson.

I'm interested in upgrading my twenty eight point eight
kilobaud internet connection to a one point five megabit
fibre-optic T-1 line. Will you be able to provide an IP
router that's compatable with my token ring ethernet LAN
configuration? :toothless |

So basically you setup the network n see how much of the total bandwidth you are using, lets say 30% at any given time, if ou do an upgrade to that network, your performance should inherantly be lower than 30%? is that what this is saying?
Like a theorem of some kind?
Cause thats how i understand it. |

OK, to clarify a little... you take baseline measurements of your network, ie, bandwidth usage, collisions, contention, latency.
Now, in the context of the original question, you compare your network performance with the baseline information, to make judgements about what and where problems are, and to check that you've actually fixed the problems when you're done.
Say you have a bung nic in somewhere on your network (assuming a single collision domain)... you may see an increase in collisions. By comparing to a baseline, you'd have a good idea of what and where the problem is, and when you've actually fixed it.
A baseline is a real measure of some metric that you're comparing against when finding and fixing problems. It's also a continuous thing, so you can compare your baseline of today to a baseline of a month ago to see usage of your network is up 17% by some measure (bandwidth, number of hosts, etc) |
