Below is a queuing system where incoming packets are classified into two queues, i.e., red and green. Each slot in the queue holds a packet. The number on the slot indicates the packet ID. The link transmits a packet from one of the queues at a time. Based on the principle of priority scheduling, round robin scheduling, and weighted fair queuing, list the packets in the order they will be transmitted onto the outgoing link. (a) Priority scheduling with the red queue being in high priority (b) Round robin scheduling starting from the red queue (c) Weighted fair queuing with a weight of 2:1, red queue to green queue and starting from the red queue arrivals classify 753 1 8642 queue (waiting area) link (server) departures
