SPRING-OPEN is not built on the latest version of ONOS (Avocet). It is built on the previous (internal) release of ONOS (Sept 2014). The source code for this project is available from the url below. To try out the prototype, you will need this version of ONOS, and you will also need the CLI that works with this version of the controller. For the switches, you have the choice of using software or hardware segment-routers. The software routers are built from a version of the CPqD OF 1.3 software switch. The hardware routers are built with Dell 4810 switches.

To get started we recommend downloading the pre-built VM from the link below. This VM has the specific version of ONOS (and its dependencies), the specific CLI, and the specific version of the CPqD OF1.3 software switch required for this project. It includes the Mininet network emulator required to run the software switches in a network topology of your choice. It also includes the recommended Wireshark dissector for OF1.3.4 protocol messages from the loxigen project.

If you do not wish to use this pre-built VM, you can download from source, and follow the installation directions below.

Pre-built VM

Download the pre-built VM (2.4 GB) from the URL:

Get a recent version of VirtualBox to import and run the VM. You can login to the VM with login:mininet and password:mininet. Then ifconfig to note the IP address assigned to VM (if you used Bridged-mode and DHCP in the VM's network settings). 

ONOS for SPRING-OPEN

If you wish to build from source, download the SPRING-OPEN version of the ONOS controller source code.

git clone https://gerrit.onosproject.org/spring-open

Compile the code.

cd ~/spring-open
mvn clean
mvn compile

 

CLI for SPRING-OPEN

 

Download a basic functioning build environment plus a few build-time dependencies. 

sudo apt-get install unzip python-dev python-virtualenv \
git openjdk-7-jdk ant build-essential

Download the source codes 

git clone https://gerrit.onosproject.org/spring-open-cli

Build the codes

cd spring-open-cli
./setup.sh

 

Dell Hardware Switches

For this you will need Dell 4810 switches. If you are a network operator and you wish to try out this prototype (for free) in your lab, contact Saurav Das or Jaiwant Virk.

 

 

 

CPqD Software Switch

  1. Download the source code

    git clone https://github.com/CPqD/ofsoftswitch13.git

  2. Go back to the specific version of Cpqd

    git checkout f308c28242de57502f06d3dee80ce47ac17b6603

  3. Apply the following patch
