Open stack neutron and opendaylight Open stack neutron and opendaylight Presentation Transcript

  • OpenStack Neutron and OpenDaylight Ramkumar Gowrishankar
  • OS Neutron and Controllers • Personal views from attending the summit – Networking in OS has kind of been neglected but is a critical piece for success of cloud orchestration (people still using nova- network because of lack of features in neutron). – OS Neutron scalability issues and single point of failure with the Network Node seems to be major pain point of community. – Neutron implementation in OpenStack is a reference implementation and not meant to scale. – Think of neutron as providing a common API similar to what nova does and not a network controller in itself. – Talking to integrators: Any deployment of scale (>1000VMs) needs a controller because neutron cannot handle the scale. – Integration with NSX or Ryu or Contrail seemed most common in deployment today.
  • OpenDaylight • Open Source SDN platform designed to provide a modular framework to program network elements (Both virtual and physical) • Collaborative project under the Linux Foundation • ODL provides: – common abstractions of capabilities via NorthBound API – framework to implement business logic for programming network elements – standard and custom south-bound APIs to connect to network elements
  • Controller Architecture www.opendaylight.org Go to: http://www.ietf.org/proceedings/88/slides/slides-88-netconf-3.pdf for more detailed architecture diagram
  • ODL and OS – match made in heaven? • ODL is a OpenSource project much like OS – Emerged from the need for an OpenSource alternative to walled gardens • Vibrant developer community that is expanding • Lot of developer interaction between the OS- Neutron and ODL community. • Lot of companies involved actively in both projects
  • OS-ODL integration in IceHouse • ML2 mechanism driver in OpenStack IceHouse to connect to ODL (support for VxLAN and GRE) • Neutron Service: Common shim that receives the messages • In Hydrogen release, 3 plugins consume the data. – Only one of the 3 can be actively running. https://www.openstack.org/assets/presentation-media/osodlatl.pdf
  • Sample architecture with OVSDB http://networkstatic.net/opendaylight-openstack-integration-devstack-fedora-20/
  • Questions If interested: Local meetup group on OpenDaylight (rtp-opendaylight) Resources: www.opendaylight.org
