2. [7 pts] Explain why packet-switching is able to exploit temporal multiplexing gains whereas circuit-switching is not. What is the tradeoff packet-switching makes to achieve this benefit ?
In temporal multiplexing, many users may be active at once, but the average over time will be lesser.
In such a case, users may need to wait for service.
Circuit switching cannot provide this because all meta-data is associated with timing and will be lost in such a case.
Packets have explicit meta-data in the form of headers and can hence be “stored” and “forwarded”.
