Suppose you are connected to a server as follows:

$$ your network card connects to a router over a link that can throughput $6$ Mbps$,$ with a negligible latency or propagation delay.

$$ Your router is connected to the server over a link that can throughput $6$ Mbps$,$ with a negligible latency or propagation delay.

$$ Your router has a negligible latency and uses store$-$and$-$forward transmission. Assume the network is uncongested.
