This document provides a quick introduction to MidoNet, a networking virtualization software plugin for OpenStack Neutron. It first briefly discusses software-defined networking (SDN) and how it separates network control and forwarding planes. It then explains how OpenStack Neutron provides networking as a service. MidoNet uses a distributed controller architecture without single points of failure to provide scalable virtual networking for OpenStack deployments using commodity hardware and switches.

- 1. Quick Introduction to MidoNet Sandro Mathys Community Manager
- 2. Agenda Ludicrously brief introductions to: 1. Software-Defined Networking (SDN) 2. OpenStack Networking 3. MidoNet: Networking Virtualization Software
- 3. Software-Defined Networking Physical Separation of Logic and Traffic
- 4. Software-Defined Networking ? Decouples control & forwarding / data plane ? Separates network logic and network traffic ? Incomplex, scalable, agile ? Centrally managed ? Commodity hardware / white box switches ? Cost
- 5. OpenStack Neutron Networking as a Service
- 7. OpenStack Compute: Nova ? Introduced with first release: Austin (2010) ? Networking integral part of Compute ? Monolithic ? Extremely Limited (L2 + DHCP) ? Flat, Flat DHCP, VLAN, Linux Bridge ? Only just basic Linux networking
- 8. OpenStack Networking: Neutron ? Introduced with 6th release: Folsom (2012) ? Pluggable, Scalable, API-Driven Network & IP Management ? L2, L3, Floating IPs, Security Groups, LBaaS, FWaaS, VPNaaS, DVR, L3HA, ¡ https://www.openstack.org/software/openstack-networking/
- 11. Distributed Controller ? Resiliency: No Single Point of Failure (SPOF) ? Scalability: Fully Distributed Architecture ? Performance: Single Virtual Hop
- 12. Distributed Architecture ? SDN intelligence at edges ? Resource usage at edge ? Grows with the cloud ? Fully Distributed Gateways ? L3 GW: Multiple BGP Border Nodes ? L2 GW: Multiple HW VXLAN Tunnel End-Points (VTEP)
- 13. MidoNet Topology
- 14. Additional Features ? Only L3 connectivity required ? Firewall bound to each vPort ? Filtered before reaching physical network ? Docker Networking via nova-docker ? Puppet Modules (others upcoming) ? Apache License 2.0 ? many many more...
