3. What is MidoNet?

4. Why do we need MidoNet?
• Demands for the virtualised networking
• Faster and more flexible provisioning
• Cloud IaaS requires virtualised networking
• Multi-tenancy
• Complete software-based solution

5. MidoNet Features
• L2- L3 Logical Switching
• Logical Routing
• State-less and Stateful NAT
• Logical and distributed Firewall
• L4 Load Balancing
• BGP and its ECMP multiplexing
• GRE and VXLAN tunneling

6. MidoNet Features
• OpenStack Neutron integration and MidoStack
• REST API
• VTEP support with OVSDB protocol
• Partial Docker integration

7. History of MidoNet (a dev’s perspective)
• Started with Midolman written in Python,
OpenStack Austin, Open vSwitch (including
userland)
• MidoNet 1.x
• Re-written with Java
• Scala was partially introduced
• Open-sourced in Nov, 2014 New!
• MidoNet 2.0 (WIP)
