How to differentiate openstack neutron extension and plugin

The extension and plug-in concepts in neutron are very similar. It took me a long time to understand the differences between the two. They are not necessarily correct yet. On the openstack wiki, you can find two definitions: Plugin: Neutron exposes a logical API to define network connectivity between devices from other OpenStack services (e.g., vNICs from Nova VM

Neutron Linux Bridge and open vswitch two kinds of plugin advantages and disadvantages comparison

has changed and helped narrow the gap between using open Vswitch and Linux bridge, including adding Vxlan support tunneling technology. But in the larger network size, the simplicity of the Linux Bridge can have a greater value.As we all know, the steps for the official installation documentation for the OpenStack community are in open vswitch before the Liberty version. And from the OpenStack User survey, the number of people using Open vswitch is much more than using Linux Bridge.Before the L

PHP Neutron class overloads the parent class method "Parent:: Method Name", Neutron parent You cannot define a function in PHP that has the same name, or a method that cannot be defined in the same class, so there is no method overload. A method that has the same name as the parent class can be defined in a subclass, because the parent class's methods are already present in the subclass so that the methods
