1 CORD: Central Office Re-architected as a Datacenter Inventing Future Access and Services Guru Parulkar ON.Lab and Stanford University parulkar@stanford.edu

2 CORD + ONOS Community ON.LAB SERVICE PROVIDER PARTNERS VENDOR PARTNERS COLLABORATORS VOLUNTEERS 40+ Companies Community includes all stakeholders of the value chain: service providers and vendors: OEM, merchant silicon, white box, disaggregated functions, system integrators, For service providers and by service providers

3 Special Thanks To Steven Rim

4 Central Office The Most Important Infrastructure for Service Providers Residential Enterprise Mobile Central Office 1 Central Office is broadly interpreted. It can be small or large and has different names in different contexts. One central office may support 10K+ residential subscribers 10K+ mobile subscribers 1K+ enterprise customers There are 1000s of CO operated by service providers It is a service provider s gateway to its customers It represents a great vantage point for a service provider Enable new services to customers Potentially a key differentiator over OTT providers

5 What is wrong with a Central Office? Source of high capex and opex Large number of COs Source of lack programmability Evolved over years Inhibits innovation 300+ Types of equipment Closed Proprietary Limits service providers ability to create new services

6 CORD Mission: Deliver to Service Providers 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 With an open CORD reference implementation

8 Commodity Servers, Storage, Switches, and I/O Domains of Use: Residential, Mobile, Enterprise Field Trial Residential volt, vsg, vrouter, vcdn Mobile Enable 5G w/ Disaggregated/Virt ualized RAN & EPC, Mobile Edge ONOS + OpenStack + XOS Enterprise SDN-WAN with programmability, packet-optical convergence POC at ONS POC at ONS Leaf-Spine Fabric Enterprise Metro Ethernet BBUs (Multi -RATs) PON OLT MACs ROADM (Core)

9 CORD: An Open Reference Implementation Hardware Blueprint Bill of Materials OCP Servers OCP Switches Access Devices Assembly Instructions Testing Infrastructure CORD POD An open service delivery platform that provides cloud economies and agility. From FTTH-as-a-Service to Software-as-a-Service. Open Source Software Core Components OpenStack ONOS XOS OCP Domain Services R-CORD: volt, vsg, vrouter, E-CORD: vce, voam, vfirewall, -- M-CORD: vbbu, vsgw, vpgw, Many configurations of CORD possible for different contexts for different operators Other Services Monitoring Ciena and Radisys to provide turn-key CORD PODs

10 Service Provider Interest: Across the Globe Service Provider AT&T Bell Canada China Unicom China Mobile NTT Comm NTT East SK Telecom Windstream Verizon Interest ONOS + CORD + Optical R-CORD, Packet-Optical E-CORD, M-CORD R-CORD E-CORD, Packet-Optical R-CORD M-CORD, Packet-Optical CORD M-CORD (R-CORD?) DT, Telecom Italia, Orange, Telefonica, EE/BT, Vodafone ONOS use cases and [R,E,M]CORD

11 OTT Validation and Strong Interest Leading OTT providers validate CORD architecture and approach and show strong interest Opportunity for us to work with them and their ecosystem to accelerate CORD development and adoption
