I have a very common question with respect to T1 links. For a T1 having bandwidth of 1.544 Mbps, the upload and download are 1.544 each. What happens when I download 1.544 Mbps of traffic. Does it affect the upload because already 1.544 Mbps is traversing the link.
I know that this is a very simple question but I came across this when working on another issue and couldmn't find myself a convincing answer.
It has no effect on upload if you are running a heavy load on download. The upload and the download are independent of each other.
Perhaps a different way of thinking about it might help. Think about having a 2 lane road that runs East to West. If there are a lot of vehicles going from East to West does that have any impact on vehicles going from West to East?
