4. Summary

What is MidoNet?

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

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

MidoNet Features• OpenStack Neutron integration and MidoStack

• REST API

• VTEP support with OVSDB protocol

• Partial Docker integration

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)
