NFV, what, why, how? Virtual Network Functions Evolution Physical Virtual Container-based • Optimized for each function • Standard high volume Hardware to maximize performance • Independent Software Vendors • Slow to deploy & update • Open Ecosystem • Fragmented non-commodity • Fast on-demand deployment & update hardware, Vertical Design • Physical install (per • Variable performance and support for optimization appliance, per site) 4

Realizing Value for Technology Providers Jumpstarting an NFV ecosystem • Standardized Framework • Proper definition of VNF • Well understood Insertion approaches VIRTUAL NETWORK FUNCTIONS • Well defined management interfaces ECOSYSTEM MANAGEMENT • Scale Out model & ORCHESTRATION • Go to market • Flexible delivery NFVi • Choose & deploy from portfolio of options SD-COMPUTE SD-NETWORK SD-STORAGE VIM • Shorter testing/deployment/upgrade cycles Towards a “Market place” of VNFs for the new wave of SW Network Technology Providers 5

Realizing Value for Operators Carrier Benefits • Service Creation • Introduction and monetization of new services • From concept to production in short timeframes VIRTUAL NETWORK FUNCTIONS • Operational Benefits MANAGEMENT ECOSYSTEM & • Ease of automation and Increased deployment agility ORCHESTRATION • Scale Out architecture • Visibility with monitoring and alerting NFVi • Reliable (Self-healing , Highly Available , no SPOFs) VIM SD-COMPUTE SD-NETWORK SD-STORAGE • Cost effective • Multi-tenant • Flexible • Shortened GTM cycle Provide customers a richer set of services. Enable a “Marketplace” 6

NFV most common use cases Flexibility and openness enables innovation in many markets vCPE/SDWAN vEPC, vIMS GiLAN vPE 7

vCPE reference design Virtualizing the Customer Premise Equipment (vCPE) Customer Premise Equipment (CPE) • Use software implementation on general purpose hardware to • Management intensive provide services to residential and business customers & • Rigid to changes in operational models Moore’s law economies of scale • performance limited • Low overhead - centralized control and management - No • static and immune to demand changes truck roll • Performance can scale with the cloud • Dynamic and flexible with ability to add and drop services easily Internet NFV Cloud 8

Let’s size it. 12

Sizing the reference design Residential vCPE Infrastructure Sizing: Number of Servers Households vCPE Adoption Servers Needed 10% vCPE penetration 2.1 M Servers 2 VM per CPE 100 VMs / server Residential Households: 30% vCPE penetration 6.3 M Servers 2 VM per CPE • China: 455.9 Million 100 VMs / server • India: 248.4 Million • Europe: 218.9 Million • USA: 133.9 Million 50% vCPE penetration 10.5 M Servers 2 VM per CPE 100 VMs / server https://en.wikipedia.org/wiki/List_of_countries_by_number_of_households 13

Sizing the reference design Residential vCPE Infrastructure Sizing: Bandwidth vCPE Adoption / Households BW per Server Speed 500Mbps / Server 10% vCPE penetration ( 2.1M Servers) 10 Mbps / CPE Residential Households: 5Gbps / Server 30% vCPE penetration (6.3M Servers) • China: 455.9 Million 100 Mbps / CPE • India: 248.4 Million • Europe: 218.9 Million • USA: 133.9 Million 50Gbps / Server 50% vCPE penetration (10.5M Servers) 1 Gbps / CPE https://en.wikipedia.org/wiki/List_of_countries_by_number_of_households 14

How big is the pie? In terms of number of servers 3 to 10 Million Servers? 2 to 10 Million Servers? Cloud NFV Industry Industry 10M servers at USD 5,000 per server = USD 50B investment … 15

Really???

Back to the drawing board … This time with the ruler!! 27

Exploring Solutions We need to look for efficiencies in multiple dimensions Bandwitdh Density Architectural FD.IO/VPP Containers Thin/Thick CPE XDP/IOVisor Serverless Tethered CPE Computing DPDK/OVS Policy based Multi tenant Networking VNFs Smart NICs New VNF Service based models SR-IOV Networking (distributed Data Path) Needed Goals: 40-100Gbps / server 100x to 1000x density Simplify operations, visibility improvement and management. Extensibility/new services. 28

About Bandwidth Bandwitdh Things to consider: • Raw PPS/BW FD.IO/VPP • Current feature set / Future feature set • Programmability & Ecosystem of developers XDP/IOVisor • Solution for VM, Containers or VM & Containers • Beyond Networking: Security/Policy at all dimensions of DPDK/OVS infrastructure • Part of Linux Kernel / External to Linux Kernel Smart NICs • Isolation of environments SR-IOV • HW assist 40-100Gbps / server 29

About Architecture Architectural Things to consider: • Thin/Thick CPE transition steps • Alternative models? Tethered CPE or uCPE Thin/Thick CPE • Do we need to change our thinking towards Tethered CPE networking (from topology to policy/services)? Policy based Networking Service based Networking Simplify operations, visibility and management. Extensibility/new services. 30

About Density Density Things to consider: • HW to VNF VM as first transition (1-1) • Complex Multitenant VMs to Single Tenant VMs (1-N) Containers • VM to Containers next logical transition (1-1) Serverless • What about other models? Equivalent to AWS Lambda for Computing networking? (N-0) • Control Plane – Data Plane Separation (N-1) Multi tenant • Vendor Ecosystem and Marketplace around the different VNFs technologies New VNF models (distributed Data Path) 100x to 1000x density improvement 31
