Consider the SDN OpenFlow network shown in the figure below. Suppose we want switch $s2$ to function as a firewall. Specify the flow table in s$2$ that implements the following firewall behaviors $($specify a different flow table for each of the four firewalling behaviors below$)$ for delivery of datagrams destined to h$3$ and h$4.$ You do not need to specify the forwarding behavior in $s2$ that forwards traffic to other routers.

Only traffic arriving from hosts h$1$ and h$6$ should be delivered to hosts h$3$ or h$4($i$.$e$.,$ that arriving traffic from hosts h$2$ and h$5$ is blocked$).$

Only TCP traffic is allowed to be delivered to hosts h$3$ or h$4($i$.$e$.,$ that UDP traffic is blocked$).$

Only traffic destined to h$3$ is to be delivered $($i$.$e$.,$ all traffic to h$4$ is blocked$).$

Only UDP traffic from h$1$ and destined to h$3$ is to be delivered. All other traffic is blocked.
