1 match IP Src = 10.3.*.* IP Dst= 10.2.*.* match ingress port = 1 IP Src = 10.3. IP Dst = 10.2.*.* OpenFlow Example: datagrams from hosts h5 and h6 should be sent to h3 or h4, via s1 and from there to s2 action forward(3) Figure 1: Traffic Engineering with Open Flow Figure 1 reveals a network where the traffic flowing from the first host which is attached to router u to the server which is attached to router z needs to be routed along the path u,v,w,z while the traffic flowing from the second host attached to router x router to the server which is attached to router z needs to be routed along the path x,w,y,z. Please describe the local flow table of each of the switches u,v,x,w,y,z (in terms of match and action rules) to enable the routing of the two traffic flows according to the constraints described above. The following IP addresses will be used for the two hosts and the server. • The first host belongs to the subnetwork 10.1.0.0/16. It is attached to router U and has an IP address of 10.1.0.1 • The second host belongs to subnetwork 10.5.0.0/16. It is attached to router X and has an IP address of 10.5.0.1 The server belongs to the subnetwork 10.11.0.0/16. It is attached to router Z and has an IP address of 10.11.0.1 Note that you can build upon the open flow example at the end of chapter 4 to answer to this question. The example is presented below.
