Part 1 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 1 Megabit/second while B - C link has transmission rate of 2 Megabit/second. There is only one packet that needs to traverse from A- B- C. The packet size is 1000 Bytes. a) 2] What are the transmission delays over link A - B and link B-C b) [2] Assume nodal processing delay at B is 1 millisecond and queuing delay at B is 3 milliseconds. Then what is the total delay from node A to node C? Assume zero propagation delay
