Indigo Virtual Switch
Indigo Virtual Switch (IVS) is a pure OpenFlow virtual switch designed for high performance and minimal administration. It is built on the Indigo platform, which provides a common core for many physical and virtual switches,
This README contains documentation to help you get started using IVS. For full documentation, see the IVS pages at Project Floodlight.
- Install required dependencies:
- Ubuntu 11.10:
sudo apt-get install libnl3-dev pkg-config python-tz libpcap-dev openvswitch-datapath-dkms
- Ubuntu 12.04:
sudo apt-get install libnl-3-dev libnl-genl-3-dev libnl-route-3-dev pkg-config python-tz libpcap-dev openvswitch-datapath-dkms
Clone the IVS repository:
git clone --recurse-submodules https://github.com/floodlight/ivs.git
The IVS daemon and ivs-ctl utility will be written to
targets/ivs-ctl/build/gcc-local/bin/ivs-ctlrespectively. They can be run directly from the build directory.
Building Debian Packages
Packaging, including init scripts, is available for Debian-based
distributions in the
debian directory. If using git we recommend
When building packages for multiple architectures and distributions we use the
build/build-debian-packages.sh script. This script uses the cowbuilder
package to create a chroot for the target distribution and build the package
inside it. The
ARCH environment variables are used to determine
the target distribution. For example:
SUITE=oneiric ARCH=i386 ./build/build-debian-packages.sh
You'll need an OpenFlow controller to use IVS. We suggest Floodlight, which should work out of the box. Follow your controller's instructions to get it running and note down its IP address.
The openvswitch kernel module must be loaded:
Now you just need to run the IVS daemon. You'll need to tell it the IP address of the controller (-c) and the initial set of network interfaces to connect (-i). Here's an example command line:
sudo ivs -c 192.168.1.10 -i eth1 -i eth2
IVS will immediately begin communicating with the controller and, depending on your controller's configuration, forwarding traffic between eth1 and eth2.
ivs-ctl add-port and
ivs-ctl del-port can be used to add and remove ports
at runtime (for example, this is used by hypervisors when a VM is started). See
ivs-ctl man page for more details.
