2. What is the difference between control and data plane in network routers?

3. A router using priority scheduling policies received the following packets in the following order (e2, f4, a1, a2, a3, b1, b2, c3, c4, d3). The number next to the letter represents the packet's priority; the higher the number, the higher the priority. Reorder the packets according to those facts.

4. A router using round-robin scheduling policies received the following packets in this order (e2, f4, a1, a2, a3, b1, b2, c3, c4, d3). Reorder the packets that are going to leave the router first.
