Detailed Description

Ryu is an Operating System for Software Defined Networking.

Ryu aims to provide a logically centralized control and well defined API that make it easy for operators to create new network management and control applications. Currently, Ryu manages network devices by using OpenFlow. You can say that Ryu is an OpenFlow Controller.

For Software Defined Networking or OpenFlow, please refer to Open Networking Foundation

Benefit to Fedora

Now Fedora (Since Fedora 17) includes OpenStack and Open vSwitch. Ryu brings open source openflow controller which can cooperates well with OpenStack.

Scope

• Proposal owners:
  • Ryu development: DONE
    • vlan support: 100% DONE
    • Ryu plugin support for Openstack Networking(Neutron, formaly Quantum): keeping update for its development
  • packaging:
    • rpm package: available at [1]
    • rpm package review [2] Work In Progress
    • make sure that it works with dependent Fedora package. Especially OpenStack and Open vSwitch
