Question 3 (40%) Consider the following transmission scenario, where Host A is going to send a large file of size 100,000 bits to Host B. Host A and Host B are 5 km apart and are directly connected using a dedicated link. The link bandwidth is 500 Mbps (i.e. 5x108 bits-per- second) and propagation speed is 2x108 m/s. Large file Host A IP addr: Port #: 192.168.123.21 13579 Host B IP addr: Port #: 192.168.123.48 24680 (a) Do you suggest using TCP or UDP as the transport layer protocol for transmission? Explain your answer. (5 marks)
