network

A network is an isolated Layer 2 networking segment. There are two types of networks, project and provider networks. Project networks are fully isolated and are not shared with other projects. Provider networks map to existing physical networks in the data center and provide external network access for servers and other resources. Only an OpenStack administrator can create provider networks. Networks can be connected via routers.
