Figure 1 is a snapshot of the moment a data packet, p, is about to enter router B, on its way to destination computer D. The outgoing link rate from B towards C is 2 Mbps and one packet has just left B while there are two more packets waiting in the buffer. The physical distance from B to C is 2m and they're connected via a copper cable with a propagation speed of 2x108 m/s. The size of each packet in Bytes is 100*s where s is the last digit of your student ID number. (maximum 300 words) i) What is the packet size? ii) Define transmission delay and calculate the transmission delay experienced by packet p in its journey from B to C. iii) Define queueing delay and calculate the queueing delay experienced by the packet p in its journey from B to C. Briefly explain how you arrived at the answer. iv) Define propagation delay and calculate the propagation delay experienced by packet p in its journey from B to C. v) Discuss which one of the delay types mentioned above is the most difficult to determine in the real world.
