Virtual networking services are implemented through a plug-in. A plug-in can use different techniques and technologies to provide isolated virtual networks to tenants. A plug-in also provides other services, such as IP address management. Because each plug-in implements all the operations included in Networking API v2.0, you do not need to be concerned about which plug-in is used.
However, some plug-ins might expose additional capabilities through API extensions, which are discussed in this document. For more information about the extensions exposed by a particular plug-in, see the plug-in documentation.
