What do Little’s result and bandwidth-delay product tell us? (Hints: The former is about a node, while the latter is about a link or path.)

Answer:

Little’s result: In a node, the mean number of packets is the product of the mean packet arrival rate and the mean delay/latency, i.e., the mean number in the box equals mean rate multiplied by mean delay.

Bandwidth-delay product: the maximum number of outstanding bits in transit in a link/path.
