How to Implement SDN

Time needed: 6 minutes

Follow from Step 1 to Step 10 in order to create SDN projects. Quick guide to create SDN . Reach us , if you want an customize SDN implement with Mininet simulation projects works for scholars.

1. SDN implementation

   The Software Defined Networking (SDN) is one of the enhanced security and automation system to create a simulation environment. We can implement real-time applications in the SDN based process based on the BGP-LS, PCEP-rich IP/MPLS Routers and also perform the Path Computation Entity (PCE) process. For make a simulation based implementation , we will use the networking simulation tools , like , mininet,NS3 , omnet++ ,python and other programming tools.

2. SDN implementation with mininet

   The Mininet is one of the virtual network emulation tool, it is used to create the network topology or launch a network topology which have the components like ,switches, hosts and a SDN controller. In commonly the Mininet simulation tool use the OpenFlow switches and routers for make a simulation.
   For implement the sdn in mininet , we need the following requirements, like 1)mininet-2.0 ,2)python-2.7 and 3)ubuntu-14.04 LTS (32 bit).
   For make a simulation we need to open the mininet installed location in the terminal window.

3. SDN execute with mininet

   SDN execute with mininet
   And also execute the command,then you can get the simulation developing window . To construct the topology, you need to click and drag the needed components from the left side window in the simulation window.
   sudo ./miniedit.py

4. SDN implementation with NS3

   For perform the process of implement the SDN , we need to integrate the OpenFlow 1.3 module into NS-3.26 package. The integration process is based on the following steps in the terminal. We can open the terminal by press the ctrl+alt +T button and open the terminal and execute the commands in the terminal,
   $ git clone https://github.com/ljerezchaves/ofsoftswitch13

5. Change the location

   Change the location
   by using this command $ cd ofsoftswitch13

6. Boot the Command

   Boot the Command
   open the terminal and boot the commands in the terminal,
   $ ./boot.sh

7. Configure the command

   Configure the command
   $ ./configure –enable-ns3-lib

8. Execute the Make command

   By using this Execute Make command $ make

9. SDN implementation in omnet++

   In the omnet++ we can integrate or implement the SDN based process , by uisng the simulation model of the OpenFlow system for INET-2.0 package. To make a SDN integration with omnet++ is , we need to import the INET-2.0 package into you workspace. For make import process , we need to process the following steps
   Import the inet source package from the stored workspace location
   For perform the process, goto file menu , then select the import option

10. Select the existing projects into workspace option

    Select the existing projects into workspace option
    Select/browse the inet location from the workspace
