# Engine network driver plugins
Docker Engine network plugins enable Engine deployments to be extended to
support a wide range of networking technologies, such as VXLAN, IPVLAN, MACVLAN
or something completely different. Network driver plugins are supported via the
LibNetwork project. Each plugin is implemented asa "remote driver" for
LibNetwork, which shares plugin infrastructure with Engine. Effectively, network
driver plugins are activated in the same way as other plugins, and use the same
kind of protocol.
## Using network driver plugins
The means of installing and running a network driver plugin depend on the
particular plugin. So, be sure to install your plugin according to the
instructions obtained from the plugin developer.
Once running however, network driver plugins are used just like the built-in
network drivers: by being mentioned as a driver in network-oriented Docker
commands. For example,
$ docker network create --driver weave mynet
Some network driver plugins are listed in [plugins](plugins.md)
The `mynet` network is now owned by `weave`, so subsequent commands
referring to that network will be sent to the plugin,
$ docker run --net=mynet busybox top
## Write a network plugin
Network plugins implement the [Docker plugin
API](https://docs.docker.com/extend/plugin_api/) and the network plugin protocol
## Network plugin protocol
The network driver protocol, in addition to the plugin activation call, is
documented as part of libnetwork:
[https://github.com/docker/libnetwork/blob/master/docs/remote.md](https://github.com/docker/libnetwork/blob/master/docs/remote.md).
