The Business Case For NFV

Sources: PA Consulting Group Network Functions Virtualization: Cost Benefits and Revenue Gains

ACG Research – Total Cost of Ownership Study Virtualizing the Mobile Core

40% Cost savings compared to a conventional core network

29%EPC virtualization alone yields savings Server savings and capacity-based scaling Operational – space, power, hardware abstraction Reduced time-to-market and transport savings

Investment payback3 years

4x fasterVirtualized infrastructure service launch

Acquisition, testing, deployment time savings

Virtualized approach cuts deployment time in half

Network Slicing Leverages Virtualization, Orchestration and Software Defined Networking

“One size fits all network” not in tune with new device and use case trends› Networks originally optimized for voice

Internet demand drove new generations of RAN and core technology

› Connected devices expanding: vehicles, wearable devices, remote sensors Different mobility needs

Network slice› Isolated, dedicated virtual network› Optimized, orchestrated and functionally

equipped for specific use cases or groups of subscribers Each slice can support different mobility characteristics and

performance requirements Move functionality (user plane/data plane/caching) to Edge

for lower latency

› Layer tailored vertical-specific applications on top of the network slice

NFV

Challenges on the Path To NFV

Technical Issues› Real-time multimedia processing – media plane is hard

Latency, clock accuracy, scheduling› Virtualization overhead

Hypervisor, virtual machines

› Performance Noisy neighbors, reliability, availability

Deployment issues› Interoperability and standards maturity

Interoperability between applications, virtualized environment and orchestration layer

Operational Issues› Interoperability paramount for automated life cycle management› End-to-end service orchestration, security and testing

Business Issues› Operational readiness – organization silos and skills gap› Licensing and business models

Signalling

Media

Signalling

Media

Real-time and Web Applications Are Not the Same

Web Request› Delays of up to a second can be acceptable to maintain

users train of thought - Nielson› Servers can send progress responses to maintain user

connection› User expectation› Loss experienced in 6% of all HTTP responses - Google

Request

Response

Real-time Multimedia Applications› More sensitive to latency and dropped

packets› Bounded - packet delay budget

LTE: <200ms target PDB for conversational voice

› As delay approaches 1 second… Stream artifacts become noticeable Intolerable effect on call quality

The Migration From COTS to NFV

COTS Virtual Machine Cloud NFV

COTS to VM› Clock source for real-time media

applications

› Hypervisor differences Resource/scheduling contention,

shared machine instances increases latency

› Extensions for low latency applications

› Noisy neighbours

VM to Cloud› Deployment challenges across 3rd

party cloud platforms Varying local rules and policies

Customization restrictions limit latency and performance tuning

› Licensing entitlement and monetization for various business models Usage, subscription, pay-as-you-go

Cloud to NFV› Standards maturity, open interfaces:

key to interoperability

› Application specific management of service quality and reliability

› Different levels of orchestration and interoperability

› Increased automation, proactive , self-healing capabilities

NFV Interoperability

New virtualization, management, and orchestration environment › Compounds interoperability challenges› Open source tweaking to optimize MANO

performance Interoperability and open interfaces key

concerns for operators› Paramount for NFV to cross the technology

Delivering Multimedia Voice and Video ServicesDecomposing Applications

Multimedia video-voice chat service elements› Application server› IMS Core

Core session control, registration, access

› IMS edge and access IMS-PSTN breakout and interworking Access SBC

MRFMRF

› Media processing Media Resource Broker (MRB)

• Load balances traffic across media resources• Intelligent and stateful resource broker

• Monitors and tracks media resources Media Resource Function (MRF)

• Processes and manipulates media

• Audio and video media stream mixing

• Tones and announcements

• Record/playback of audio/video

• Transcoding, transrating, transizing

Separating media processing from the applications leads to better resource utilization and more consistent user experience

MRB/MRF architecture better aligns with NFV decomposition principles

Delivering Rich Media Services in Multivendor Virtualized Environments

NFV Infrastructure› Physical compute, storage, networking › Virtualization layer - VMs or containers

VNF layer› Virtualized applications› Stand alone or composite VNFs

NFV Orchestrator› NFV brains› Network services chaining

VNF Manager› Instantiation, configuration, modification and

termination of VNFs› Scaling out, in, up or down of VNFs› Manages virtual and physical functions

VIM› Controls, manages, orchestrates NFVI resources› Cloud operating system

NFV Guiding Principles

Real-time multimedia VNFs › Require high performance virtualized environments

Architectural flexibility› Software architected for the cloud

Modular

Flexible deployment

Functional decomposition

› Support technology advancements at the virtualization layer - Virtual machines, container technology

VNF automation, scalability and programmability are not “nice to haves” rather “must have” goals› Intelligent automated lifecycle management

› Application and system KPIs and associated policy Critical to optimize VNF application performance and scalability to realize the

full potential of a virtualized environment

Interoperability is paramount› Fast onboarding with open APIs

› Multi-vendor deployment flexibility
