3. [10 points]: Consider the TCP reliable data transfer protocol. (a) The sender sends two packets, one with 10 bytes of data and the other with 20 bytes of data. The initial sequence number is 83 and the ACK for the first packet is lost. Draw a timeline showing the sequence of events in this scenario. b) Explain how TCP flow control works. Figure 1: Network for Problem 4 and 5 4 [10 points: Link-state routing: (a) Explain how link-state routing works. Give an example of an Internet routing protocol based on link-state routing (b) Apply Dijkstra's algorithm to obtain the routing table for node a in the network given in Figure 1
