Link 1 | Transmission rate: 10 Mbps Link Length: 2 Km Link 2 Link 3 Transmission rate: 100 Mbps Link Length: 1 Km Transmission rate: 1 Mbps Link Length: 500 Km Signals propagate across the network at 3.0 x 10^8 m/sec. Assume the length of a packet is 5000 * the last non-zero number in your student ID. Tell me what that value is: bits per packet. a. If you have an infinite supply of packets at the PC on the left, how many of these packets can you send across the link 1 in one second? Always give the number of whole packets only, please: b. How many can you send across link 2 in one second? c. How many packets can you send across link 3 in one second? d. If the processing delay in each router is negligible (rounds to zero), will your packets queue in either of the routers? Mark in which ones: Link 1-to-Link 2 Router Link 2-to-Link 3 Router Will either router buffer ever fill causing packets to drop? Y N e. If you sent packets back from the server to the PC, would those packets queue in either router? Mark in which: Link 1-to-Link 2 Router Link 2-to-Link 3 Router Will either router buffer ever fill causing packets to drop? Y N
