The intention of the presentation is to give a birds-eye view of networking in Openstack
based on the "default" setup with Neutron/Openvswitch. It's mostly aimed at people
familiar with network concepts, but not necessarily with deep Openstack experience.
Concepts that will be talked about include:
- General Neutron design
- ML2
- Openvswitch
- Overlay technologies like VXLAN and GRE
- Provider networks and Tenant networks
- Openstack routers, networks and subnets
- Security Groups
- Network Partitioning
- Network namespaces
- Floating IPs / NAT / PAT
- Address scopes and Subnet pools
- Neutron as a BGP speaker
- Distributed Virtual Routers
- HA routers
- L2 and L3 agents
- Plugins like for example VPNaaS and LBaaS
- DHCP and Metadata services
The attendees will walk away from this session with general knowledge about many aspects of networking in Openstack with standard Neutron/Openvswitch setup. It's intended to give an overview of what options and features are available and a basic grasp of what they do and how they work.
