transmission rate between source and switch is Ri, and the rate between switch and destination is R2 L bits per packet destination Source - momitted. recewe all the packets before At T=4/R1. the entire packet is xmitted by source and it is recewed Between somice and stront destmation, we here links and m-L (15 pts) 2. Suppose there is one packet switch between a source and destination. The R1 bps R2 bps (6) 2.1) Assume the switch uses store-and-forward packet switching, suppose a racket will length L is transmitted from source to destination, what is the send the packet of size L bits. y the switch which transtort the transmission and the enter epacket (4 pts) (2.2) What is the transmission delay from source to destination if we have 4 packets with length L to be transmitted? (Assume R1 R2=R), How about N packets, The delay the source to the switch -HR what is the transmission delay, seadmy time of est packet from the reach ome the 1st parket reacte the switch = Time the ce packet witch = 24/R. Exery HR packet will be received at the desman (3 pts) 2.3) What is the transmission delay of sending P packets (each packet's length is L) over M Links of transmission rate R. m witches. (4pts) (2.4) Consider sending a packet from source to destination over a fixed route. List the delay component in the end-to-end delay. Which of these delay are constant and which are variable? Etal delay
