ONF – An Operator Led Consortium with A Track Record of Impact “Nearly 40% of all end-customers will have service provided by … CORD by mid-2021” Roz Roseboro Heavy Reading “70% of operators worldwide are planning to deploy CORD” Michael Howard IHS Markit 

CORD Overview 4 

CORD Highlights • Network edge is undergoing a major transformation • Represents a huge opportunity • CORD has emerged as a compelling platform for the new network edge • Leverages disaggregation, open source and white boxes • Puts SDN, NFV and cloud technologies into a compelling solution • Many service providers experimenting and have plans for trials and deployment • CORD has a growing community of 60+ companies representing various stakeholders • CORD has been demonstrated to support all three domains of use • Residential (R-CORD) • Mobile (M-CORD) • Enterprise (E-CORD) 

Where do Service Providers Face Challenges and Spend Their Money? 6 Image Source: https://www.telarus.com/uploads/files/795/xlarge/att-network-map.jpg Backbone is a relatively small part of the network ~ 80% of spend is in the Network Edge 

Central Office – The Most Important Infrastructure for Service Providers Central Office Residential Enterprise Mobile • CO is a service provider’s “gateway” to its customers • There are 1000s of COs • ‘End-to-end’ user experience controlled by this facility 1Central Office can be small or large and has different names in different contexts. 7 

Commodity Clouds Users Central Offices This Outdated Edge is Greatest Opportunity for Operators Telco & IX Cloud 

Commodity Clouds Users Edge Cloud This Outdated Edge is Greatest Opportunity for Operators Telco & IX Cloud 

Commodity Clouds Users Edge Cloud • Subscriber experience dictated from here • Human Reaction time: 210ms • Latency to Centralized Cloud: 100 – 400ms • Emerging Applications Require Edge Processing • AR visual overlays • Autonomous Vehicle Coordination • IoT Battery Life (50-75% improvement with edge processing) This Outdated Edge is Greatest Opportunity for Operators Edge Processing is Vital Telco & IX Cloud 

CORD Mission: Enable the Edge Cloud Economies of a datacenter Infrastructure built with a few commodity building blocks using open source software and white boxes Agility of a cloud provider Software platforms that enable rapid creation of new services All in an Easy to Consume Platform 11

Service Provider Traction North America • AT&T: R-CORD, M-CORD (Multi-Service Edge), vOLTHA • Verizon: M-CORD • Sprint: M-CORD • Comcast: R-CORD • CenturyLink: R-CORD • Google: Multi-access CORD Asia & Australia • China Unicom: M-CORD, E-CORD • China Mobile: M-CORD and E-CORD • NTT, NTT East: IP+Optical, R-CORD • SK Telecom: M-CORD • Telstra: M-CORD • Reliance Jio: M-CORD Europe • Deutsche Telekom: R+M-CORD (Hybrid CORD) • Telefonica: R-CORD, M-CORD • Telecom Italia: M-CORD • Colt: R-CORD • Turk Telekom/Netsia: M-CORD & ONOS SDN Control Interest continues to grow on a monthly basis. Many successful POCs and lab trials and a few field trials 

CORD Differentiators and Value Prop • Unique and strong partnership • ONF + Service Providers + Vendors + a growing collaborating community • Integrated solutions platform for “service” delivery • Complete integrated platform: ONOS, Trellis, XOS, Docker, OpenStack, … • A common platform for three critical (and massive) domains of use • Residential, enterprise and mobile • Leverages merchant silicon and white boxes • Not only for servers and switches but also for access (GPON, LTE/cellular, …) • Designed to be Customized • Vendors and Operators can customize, add VNFs, and deliver superior solutions faster 16

Specialized Edge Datacenters with Centralized Orchestration CORD = Edge Optimized Cloud – Unique Capabilities for the Edge • Subscriber Access • Real-time response and control • Combination of Micro-Services and Fabric-Services CORD Central Office CORD Central Office CORD Edge Cloud Edge Service Edge Service Edge Service Edge Service Composite-VNFs Users Telco Cloud (e.g. AT&T AIC) Users Users CORD exposes a set of Edge Services to ONAP 

Not All Services Should be Run on a Server • CORD Service Building Blocks – Micro-Services - Images that run in containers on servers – Fabric-Services - Functions that run in switches • CORD Service Graphs chain micro-services and fabric-services – Elements run on servers (x86 or ARM) – Elements run in the OpenFlow (or P4) enabled dataplane • Different price/performance ratio CORD Service Micro-Service Fabric-Service Fabric-Service Micro-Service XOS Service Graph • CORD Edge Services can be instantiated and controlled by a global orchestrator • As the dataplane becomes more programmable (P4), even more functionality can be moved into the fabric
