(Solved) : 1 Packets Arrive Beginning Slot Thus Figure Packets 1 2 3 Arrive Slot 0 Already Packets Qu Q38038920 . . .
1. Packets (if any) arrive at the beginning of the slot. Thus inthe figure, packets 1, 2, and 3 arrive in slot 0. If there arealready packets in the queue, then the arriving packets join theend of the queue. Packets proceed towards the front of the queue ina FIFO manner. 
2. Consider the figure below, which shows a leaky bucket policer being fed by a stream of packets. The token buffer can hold at most two tokens, and is initially full at t-0. New tokens arrive at a rate of one token per slot. The output link speed is such that if two packets obtain tokens at the beginning of a time slot, they can both go to the output link in the same slot. r= 1 token/slot b 2 tokens Arrivals t=4 t=2 t=0 Packet queue (wait for tokens) The timing details of the system are as follows: Show transcribed image text
