1- What is NFV: Network Function Virtualization
Leverage IT virtualization techniques for telco functions
• Use standard servers and storage
• Applicable to telco network functions
• Initiative from Tier 1 Operators & Vendors launched as a new Industry Specification Group (ISG) in ETSI
Key Benefits
• Reduced equipment costs
• Faster time to market
• Resource sharing
• Targeted service introduction
• More flexible, programmatic operations
virtualize network functions: from Home or Enterprise Gateway to Access/Core telecom network & Data centers

Ex#: IMS MSE/MRF modeling into VNF
The Multimedia Services Environment is decomposed into “VNF” or “VNFC” :
The IMS MRF VNF that groups the MRB and the MRF (composite VNF) composed of MRF-C, MRF-P and MRF Storage VNFC
The OCSEE Application server that includes a SIP AS function, a J2EE container, an internal WEB LB and a Reporting and Monitoring function, is it considered as VNFC (VNF Components)
The SIP Load Balancer is aimed to load balance the incoming SIP Session towards several SIP AS instances. It’s a signalling function that supports the ISC IMS interface
AS storage is an external storage for the AS data (SIP & WEB) SIP Load Balancer

Multiple VIM & NW Controller Key Highlights:
• VNFM & NFVO could be across multiple NFVI Domains, iemultiple VIM
• VIM could interface multiple Network Controllers
• NFVO could request a “WAN manager” to bridge 2 PoP, PoP1 & PoP2 via a WAN. Meaning NFVO not only interface with VIM but also with WAN manager
• VNFM does not interact with WAN manager, only to NFVO and VIM
• WAN can support PNFSource: MANO GS

feet ? How can I ensure there is no security breach in 1.7M lines ?
? How does Openstack prevent back doors ?
? How does Openstack support secure boot, certified VM?
? How can I define security rules for an SDN application to change a flow table on an SDN switch that is provided by a IaaS Provider that may change along the life of the service ?
? How can I ensure that the memory I am sharing will not be accessed by somebody else ?
? Can I present the system admin to access my personal data
etc
Many blocks interact with Keystone
Keystone is not the only entity that deals with security
Keystone deals with security & policies, but NFV will need end to end security & policies across end to end network, at ?NFVO level : how to synchronize?
