Subject [PROPOSAL] A networking plugin to integration with BigSwitch network controller platform
Date Thu, 03 Jan 2013 06:20:33 GMT
Hi All,

Happy New Year to Everyone!
First of all, I am new to the community and very excited to have the
opportunity to work on the project.

I would like to propose a networking plugin that will support
openflow-based cloud networking solutions through BigSwitch's BVS (Big
Virtual Switch) application.

BVS is one of the SDN applications available for the BigSwitch network
controller. BVS application provides network virtualization, manages
isolated and virtual networks on top of the underlying physical and virtual
switch infrastructure. These virtual networks correspond directly to the
groups of VMs, servers, and other devices that need their own secure
connectivity. The virtual networks are programmed into the physical and/or
virtual switches without having to separately configure individual network

The proposed CloudStack networking plugin will bring the OpenFlow-based
standard network virtualization technology to CloudStack.

There won't be any change to the existing CloudStack workflow. In a typical
deployment, all OpenFlow-enabled physical and virtual switches and other
network resources are configured to be managed by the BigSwitch
controller(s). When a guest network is created, the plugin will create a
corresponding virtual network in the BVS  When a guest VM is launched, the
VM is automatically assigned to its configured guest network(s).
The BVS application will provide network isolation and connectivities among

More detailed product description is available on the

Please let me know if you need more information.
