6. Consider a file of size 10 MB needs to be sent over network with 10 Mbps bandwidth. The file is sent as a collection of packets, each of size 1 KB. However, packets can be sent without waiting for the acknowledgements. The underlying protocol mandates a 4*RTT wait time after every 20 packets are sent for the ACKs to come. If there are any packet losses, (i.e., no acknowledgement), all the lost packets are retransmitted after the scheduled transmission of the entire 10 MB file is over as a new set of packets using the same protocols and its rules. Assume the RTT to be 20ms. (a) Calculate the latency if there is no packet loss in the network. (b) Calculate the latency if 10% of the packets are lost. (10 points)
