How many milliseconds (ms) does it take for a packet of length 1,000 bytes to be delivered from the sending host to the receiving host over a link of distance 2,000 km, propagation speed 2.5×108 m/s, and transmission rate 50Mbps (consider both transmission delay and propagation delay)?

Assignment1Questions: (50 points) 1, (6 points) Suppose there are exactly two packet switches (switch1 and switch2)between a sending host and a receiving host. The transmission rate between the sendinghost and switch1 is R1, 200Mbps. The transmissions rate between switch1 and switch2 and between switch2 and the receiving host are R2, 400Mbps and R3, 500Mbps, respectively. […]
