11. 11© Copyright 2015 EMC Corporation. All rights reserved. A NEW APPROACH TO NETWORKING Network virtualization is all about abstracting network services and operations from the underlying hardware. This moves network configuration decisions to a central location and enables you to manage your network at the speed of software Configuration is done with knowledge of the entire network state
