Assignment Description    For  this  assignment,  you are  required  to write  a  report  consisting of  a  section on  following questions  i.e.  (Question 1 to 4). For question 4, you all have to demonstrate in the lab on week 8 lab.

1. Describe  how  routing  is  implemented  in  Software  defined  networking  (SDN).  What  are  the  advantages of SDN routing over traditional routing?

2. Write a review of two software defined controllers.   3. What is the role of ARP and ICMP while implementing a controller?  4. Create following topology as shown in Figure 1 using Mininet:

Figure 1: Network topology.

i) Identify the interface connecting each device.  ii) Create appropriate subnets and assign IP addresses to the interfaces.  iii) Create a static routing table for the routers as given in above network. Entries to the routing table

can be as: [Des: IP, Next Node/Hope, Network Mask, Interface]  iv) Demonstrate the IP forwarding controller by creating logic for  level two switches and Level three

routers.

Note: Si  {i=1,2,3,…,n} is  level 2 switch that do not perform routing. Ri  {i=1,2,3,…,n}  is  level  three routers. Hi

{i=1,2,3,…,n} is the host. These do not have forwarding information. The routing table is rather stored in the  controller.
