Features
|
|
========
|
|
|
|
Open Virtual Network (OVN) offers the following virtual network
|
|
services:
|
|
|
|
* Layer-2 (switching)
|
|
|
|
Native implementation. Replaces the conventional Open vSwitch (OVS)
|
|
agent.
|
|
|
|
* Layer-3 (routing)
|
|
|
|
Native implementation that supports distributed routing. Replaces the
|
|
conventional Neutron L3 agent. This includes transparent L3HA :doc::`routing`
|
|
support, based on BFD monitorization integrated in core OVN.
|
|
|
|
* DHCP
|
|
|
|
Native distributed implementation. Replaces the conventional Neutron DHCP
|
|
agent. Note that the native implementation does not yet support DNS
|
|
features.
|
|
|
|
* DPDK
|
|
|
|
OVN and the OVN mechanism driver may be used with OVS using either the Linux
|
|
kernel datapath or the DPDK datapath.
|
|
|
|
* Trunk driver
|
|
|
|
Uses OVN's functionality of parent port and port tagging to support trunk
|
|
service plugin. One has to enable the 'trunk' service plugin in neutron
|
|
configuration files to use this feature.
|
|
|
|
* VLAN tenant networks
|
|
|
|
The OVN driver does support VLAN tenant networks when used
|
|
with OVN version 2.11 (or higher).
|
|
|
|
* DNS
|
|
|
|
Native implementation. Since the version 2.8 OVN contains a built-in
|
|
DNS implementation.
|
|
|
|
* Port Forwarding
|
|
|
|
The OVN driver supports port forwarding as an extension of floating
|
|
IPs. Enable the 'port_forwarding' service plugin in neutron configuration
|
|
files to use this feature.
|
|
|
|
* Packet Logging
|
|
|
|
Packet logging service is designed as a Neutron plug-in that captures network
|
|
packets for relevant resources when the registered events occur. OVN supports
|
|
this feature based on security groups.
|
|
|
|
* Segments
|
|
|
|
Allows for Network segments ranges to be used with OVN. Requires OVN
|
|
version 20.06 or higher.
|
|
|
|
.. TODO What about tenant networks?
|
|
|
|
* Routed provider networks
|
|
|
|
Allows for multiple localnet ports to be attached to a single Logical
|
|
Switch entry. This work also assumes that only a single localnet
|
|
port (of the same Logical Switch) is actually mapped to a given
|
|
hypervisor. Requires OVN version 20.06 or higher.
|
|
|
|
|
|
The following Neutron API extensions are supported with OVN:
