NFV the new business of the network Why now? Change is not optional Improves OPEX Move from Telco opex model, to lower cost IT opex model Lowers CAPEX Move from dedicated appliances to virtualization model based on IT technology Accelerates time to market Deploy new software and new services quickly and easily (from months to minutes) Accelerates innovation via an open platform Broaden access to partners who can innovate not just NEPs but also start ups, ISV s Delivers business agility Rapidly scale up or scale down applications modify QoS, deliver new services faster 2

What is Network Functions Virtualization (NFV)? Ability to provide network functions on industry standard platforms Evolution of IT virtualization techniques for core network functions Use standard servers and storage Reduced equipment costs Faster time to market Resource sharing Targeted service introduction Classic network appliance approach Message router WAN acceleration CDN DPI Session border controller Firewall Network virtualization approach Software vendors Virtual appliances Orchestrated, automatic, and remote install Implement network functions in SW It can be moved to, or instantiated in, various locations in the network as required, without the need to install new equipment! 3 Carriergrade NAT PE router Tester/QoE monitor BRAS SGSN/ GGSN Radio access network nodes Fragmented non-commodity hardware Physical install per appliance per site Hardware development large barrier to entry for new vendors, constraining innovation and competition Standard high-volume servers Standard high-volume storage Standard high-volume Ethernet switches

NFV Challenges for the CSP NFV adoption is not an option, yet it is deeply transformational and introduces risks Infrastructural Cost of transformation Need Telco-grade availability, performance and SLAs Future proof architecture to cope with NFV uncertainty Operational Integration within existing OSS/BSS environment How to maintain customer and services view correlated to underlying infrastructure Need automation to enable NFV agility How to ensure reduced operations costs while deploying NFV Organizational CIO vs. CTO scope of responsibility Automation will create redundancies and have social impact Purchase chain and interfacing will drastically change 4

NFV Operational Challenges for the CSP CSPs demand vendors to focus also on operational challenges Seamless integration with existing OSS/BSS systems, processes and practices Correlation across Network Service, VNF, infrastructure and network to provide end to end view of services to guarantee customer experience Management automation to enable NFV agility Affordable and flexible solution with multi-vendor capabilities that removes vendor dependency while maintaining telco-grade availability NFV transformation requires orchestration capability 5

Addressing the challenges through orchestration Key component of NFV management is Orchestration NFV Orchestration role Maintain end to end view of Infrastructure, VNFs and Network services to provide proper visibility of customer experience Automate deployment and monitoring across multiple VNF and VIMs Ensure integration with OSS to guarantee NFV manageability Business case 1 Operating cost Physical Virtual NFV with orchestration Business case 2 Installation costs NFV Orchestration benefit Avoid creating new technical or organizational silos of management for NFV Easily integrate virtualized network functions into OSS and IT environment Reduce risk by implementing a standard based approach Avoid vendor lock-in at infrastructure or VNF level Enabling Successful Business Cases Y-1 Y-2 Y-3 Y-4 Net margin Y-1 Y-2 Y-3 Y-4 Y-5 Net margin Y-1 Y-2 Y-3 Y-4 Y-1 Y-2 Y-3 Y-4 Y-5 6

Handles the type of management functionality required by devices NS Network service; A composition of network functions (VNF or PNF) and defined by its functional and behavioral specification At least one network function needs to be a VNF PNF Physical network function Today s devices 26
