3 OpenStack and OpenDaylight Integration Network/Control Node Controller node Neutron OpenDaylight* ML2 Plugin Networking-odl ML2 DB Neutron Northbound ovsdb/netvirt Yang Model Management Network Data Network Public Network Compute Node VM VM OVS Networking Node DHCP Agent OVS Internet Router

4 Networking-ODL and ODL Neutron Northbound Key components of the integration OpenStack networking-odl OpenStack Neutron Stadium Project Basically follows openstack rule, but a bit more flexible ODL Neutron Northbound Work in tandem Each has its own project governance

11 V2 Driver Details Journal based Ordered queue of operations Dependency graphs A-synchronous from the API DB level locking Journal thread Maintenance thread Full sync Recovery Cleanups

12 V2 Driver Benefits A-synchronous Free up Neutron faster Fits ODL design paradigm Ordered & Dependency checked Same resource won t hit race conditions Dependant resources won t hit race conditions DB level locking Supports HA deployment of Neutron Scale out

13 V2 Driver Shortcomings & Possible Improvement A-synchronous No way to know resource state in ODL However.. ODL is actually a-sync, so need to tackle somehow Becomes a bottleneck on scale Consider allowing journal thread to scale on single server Move dependency calculations to row creation Complexity is bug prone Need to simplify as much as possible

14 Pseudo agent port binding Store in agentdb for port binding neutron/networking-odl ODL controller Enabled in Ocata Support multiple vif types ovs-dpdk vpp sriov OVS DB external-ids hostconfig host_id host_type vif-type vif-details...
