§ NFV is a direction that Service Providers are headed in an effort to reduce OPEX § It allows a generic hardware complex with specialized software applications. § It trades off specialized hardware for less optimized common platforms § It uses standard management and orchestration tools § § © 2012 Cisco and/or its affiliates. All rights reserved. NFV and Orchestration required is not simple but - It is heavily leveraged from the data center - It is mainstream technology - It could have significant advantages especially for scaling & OPEX Physical versus virtual will be a choice 29
