Computer Networks

Consider the SDN network shown in Figure 2. Specify the flow table entries in s2 (each row contains "match" and "action" fields) according to the following behaviors: . datagrams arriving on port 1 from hosts h5 or h6 that are destined to hosts h1 or h2 should be forwarded to port 2; datagrams arriving on port 2 from hosts h1 or h2 that are destined to hosts h5 or h6 should be forwarded to port 1; e datagrams arriving on ports 1 or 2 that are destined to hosts h3 or h4 should be delivered to the respective host; e datagrams from host h3 to hosts h1, h2, h5, and h6 should be forwarded to port 1; datagrams from host h4 to hosts h1, h2, h5, and h6 should be forwarded to port 2; only TCP traffic is allowed between hosts h3 and h4 (i.e., UDP traffic between them is blocked) Host h6 10.3.0.6 Open Flow controller 4 Host h5 10.3.0.5 S1 Host h4 10.2.04 4 2 4 Host h 1 10.1.0.1 Host h2 10.1.0.2 Host h3 10.2.0.3 Figure 2.
