PACKET SCHEDULING (SCENARIO 2, RR).
Consider the pattern of red and green packet arrivals to a router's output port queue, shown below. Suppose each packet takes one time slot to be
transmitted, and can only begin transmission at the beginning of a time slot after its arrival. Indicate the sequence of departing packet numbers (at t
= 1, 2, 3, 4, 5, 7, 8) under round robin scheduling, where red starts a round if there are both red and green packets ready to transmit after an empty
slot.
Give your answer as 7 ordered digits (each corresponding to the packet number of a departing packet), with a single space between each digit, and
no spaces before the first or after the last digit, e.g., in a form like 7 6 5 4 3 2 1).
