It is about computer network

Part 1 B 1. A C Assume a node A is sending a packet to router B who is forwarding the packet to destination C. A - B link has transmission rate of 2 Megabit/second while B-C link has transmission rate of 3 Megabit/second. There is only one packet that needs to traverse from A - B - C. The packet size is 9000 Bytes. a) [3] What are the transmission delays over link A - B and link B- C? Show your answer with clear explanation. b) [2] Assume nodal processing delay at B is 2 millisecond and queuing delay at B is 5 milliseconds. Then what is the total delay from node A to node C? Assume zero propagation delay. Show your answer with clear explanation
