Single Network Control

This example changes single openflow network into one big layer2 switch, so the following scripts configure ODENOS as below:

 [LearningSwitch l2sw1]
          |
  [Network network2]
          |
[Aggregator aggregator1]
          |
  [Network network1]
          |
[OpenFlowDriver driver1]
          |
          |
          | (OpenFlow Secure Channel)
          |
          |	  
      (mininet)
 h1 -- s1 -- s4
       |     |
       |     |
      s2 -- s3 -- h2

Setup

  1. mininet

    Install ODENOS with python and ruby environments. see Getting Started with ODENOS.

  2. mininet

    $ sudo apt-get install mininet

Run

1. Start ODENOS

$ ./start_odenos.sh start

2. Start Mininet

$ sudo ./start_mininet.py

3. Check ODENOS status

####1. check components

$ curl http://localhost:10080/systemmanager/components
