• Large open source project
within Linux Foundation
• Platform for building
programmable, software-
defined networks (SDN)

• Neutron using OVS backend and
VXLAN for tunnels
• Turn off Neutron server and
Neutron’s OVS agents on all hosts
• Clear existing OVS config and set
OpenDaylight to manage switch
• Configure Neutron to use
OpenDaylight’s ML2 driver
• OpenDaylight now creates
network endpoints for instances
and manages traffic for them

Pros and Cons
• Pros: Support for all southbound interfaces of OpenDaylight; therefore,
work with wide range of network elements and existing deployments
• Cons: OpenDaylight, like OpenStack, is complex to install and operate,
documentation is not always accurate and up to date
 Pros and Cons of using a large, rapidly developing open source project
