OpenStack network architecture

OpenStack network architecture

OpenStack Networking manages virtual networks that connect virtual server instances to each other and to external network. Also, OpenStack networking handles network configuration of instances, virtual firewalls, and floating IP addresses.

Tenant virtual networks are overlay networks on top of physical and logical infrastructure of a data center network. Both the overlay network creation and host network configuration depend on the back end that you use.

MCP supports the following network technologies as back ends for OpenStack Networking:

  • Neutron Open vSwitch (OVS)

  • OpenContrail
