I need help with the following....... HOMEKNOWLEDGE CHECKSPACKET SCHEDULING (SCENARIO 2, FCFS).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 betransmitted, 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 FCFS scheduling. 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).[Note: You can find more examples of problems similar to this here.]arrivalspacket inservicedeparturest123 4↓↓0? ? ? ?15Answer2 34?5676? ?7 8CHECKCHAPTER 4 - SECTION 2↑
