    Team • Edgecore Networks Solution Engineer • SDNDS-TW Co-Founder Ref: https://www.linkedin.com/in/phil-huang-09b09895/ ONF: Open Networking Foundation
  3. 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
  4. CORD Overview 4

  5. 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)
  6. 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
  7. 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
  8. Commodity Clouds Users Central Offices This Outdated Edge is Greatest

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 Commodity Clouds Users Edge Cloud This Outdated Edge is Greatest

    Opportunity for Operators Telco & IX Cloud
  10. 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AR visual overlays • Autonomous Vehicle Coordination • IoT Battery Life (50-75% improvement with edge processing) This Outdated Edge is Greatest Opportunity for Operators Edge Processing is Vital Telco & IX Cloud
  11. 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

  15. 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
  16. 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
  17. CORD Within the Open Source Landscape 17

  19. 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
  20. 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
  21. Open Source Landscape CORD’s Relationship to OPNFV 21

  22. Both Leverage Many Common Upstream Open Source Projects Single Pre-Integrated

    Platform Easy to Extend and Customize Lots of Different NFVI Options Includes Ready-to-Deploy Services Vendor VNFs Easy to Add VNFs Out-of-Scope 1 Platform 3 Solutions (Residential, Enterprise & Mobile) 63 Scenarios (combinations) Various combinations of projects upon which VNFs and Solutions can be Developed CORD OPNFV Addressing needs of the NFV Space Similarities Differences Compare and Contrast with
