@ -44,7 +44,7 @@ Networks consist of *many* endpoints.
`NetworkController` object provides the entry-point into libnetwork that exposes simple APIs for the users (such as Docker Engine) to allocate and manage Networks. libnetwork supports multiple active drivers (both inbuilt and remote). `NetworkController` allows user to bind a particular driver to a given network.
**Driver**
`Driver` is not an user visible object, but drivers provides the actual implementation that makes network work. `NetworkController` however provides an API to configure any specific driver with driver-specific options/labels that is transparent to libnetwork, but can be handled by the drivers directly. Drivers can be both inbuilt (such as Bridge, Host, None & overlay) and remote (from plugin providers) to satisfy various usecases & deployment scenarios. At this point, the Driver owns a network and is responsible for managing the network (including IPAM, etc.). This can be improved in the future by having multiple drivers participating in handling various network management functionalities.

**Network**
`Network` object is an implementation of the `CNM : Network` as defined above. `NetworkController` provides APIs to create and manage `Network` object. Whenever a `Network` is created or updated, the corresponding `Driver` will be notified of the event. LibNetwork treats `Network` object at an abstract level to provide connectivity between a group of end-points that belong to the same network and isolate from the rest. The Driver performs the actual work of providing the required connectivity and isolation. The connectivity can be within the same host or across multiple-hosts. Hence `Network` has a global scope within a cluster.
