Agenda

1. Self Introduction2. Open vSwitch vs MidoNet3. MidoNet Advantages4. Understanding MidoNet5. MidoNet Community

Open vSwitchvs MidoNet

Neutron Plugin Comparison

Neutron Open vSwitch (OVS) Plugin Architecture

MidoNet (MN) Architecture

OVS: Centralized Controller Model (I)

MN: Distributed Controller Model

OVS: Centralized Controller Model (II)

MN: Distributed Edge Model

OVS: Active / Standby Gateway Model

MN: Fully Distributed Gateway Model

MidoNet Advantages

Overview

Distributed Networking Services

⚫ Logical Switching⚫ Logical Routing⚫ Logical Firewall⚫ Logical Layer 4 Load Balancer⚫ MidoNet API

Distributed Controller

⚫ Resiliency: No Single Point of Failure (SPOF)⚫ Scalability: Fully Distributed Architecture⚫ Performance: Single Virtual Hop

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)

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...
