1. Introduction of ONF CORD Project Phil Huang <phil@cord-ambassadors.org> Open Networking Solution Engineer, Edgecore Networks Corporation 2017/07/18, OpenStack Day Taiwan 2017, Taiwan #OpenCORD #ONOSProject
2. • Phil Huang ◦ Edgecore Network Solution Engineer ◦ ONOS/CORD Ambassador ◦ SDNDS-TW Co-Founder Who am I? 2 Ref: https://www.linkedin.com/in/phil-huang-09b09895/
4. 4 Open Networking Foundation (ONF)
5. 5 Projects in ONF
6. Reinventing Central Offices For Efficiency & Agility opencord.org
7. 7 What is CORD? SDN + NFV + Cloud Open Source Software Commodity Hardware (Servers, White-Box Switches, I/O Blades) CORD: Central Office Re-architected as a Datacenter
9. Vendor Lock-In Hardware 9 Server Trends X86 Hardware + Software Central Office (CO) 局端
10. Traditional 3-Tier Network • Core / Aggregation / Access 10 Network Design Transformation Clos Network • Leaf / Spine
11. 11 Overview of CORD
12. 12 Current Teleco Central Office of AT&T Ref: http://www.netmanias.com/en/post/blog/10408/gigabit-internet-sdn-nfv/at-t-s-cord-the-ultimate-architecture-born-after-decades-of-innovation-in-the-communications-network CO: Central Office
13. 13 Disaggregated Optical Line Termination OLT: Optical Line Termination GPON: Gigabit Passive Optical Network
14. 14 ONF R-CORD of AT&T Ref: http://www.netmanias.com/en/post/blog/10408/gigabit-internet-sdn-nfv/at-t-s-cord-the-ultimate-architecture-born-after-decades-of-innovation-in-the-communications-network

20. 20 Composing Services
21. 21 CORD Virtual Infra Architecture
22. • Provides connectivity within and between services • Any network virtualization technology can be used • CORD VTN ensures OVS is configured properly for operation 22 CORD Virtual Tenant Network (VTN)
23. • Hardware environment ◦ Dual E5-2670 v3 / RAM 64GB / Intel Dual 10G NIC • Optimal configuration ◦ 16 VMs, 128 S-Tags with 31 C-Tags each • Target was ~4000 subscribers per server • Memory usage ◦ 40-50% idle with 46GB RAM used 23 Scalable vSG Performance Ref: https://drive.google.com/file/d/0B6cvQiEoZCrzeWh5cTFFRDlvVlE/view CORD node over OpenStack VM Router VM Namespace Router Container
24. • 24 Field Trial: NTT EAST Ref: https://wiki.opencord.org/display/CORD/NTT+and+R-CORD
25. 25 Lab Trial 1: GE-PON-OLT
26. 26 LAB Trial 2: PPPoE
27. Open and Community-Driven ambassadors.onosproject.org
28. Designed to empower anyone who is passionate and knowledgeable about ONOS and/or CORD • Promote either project in their region • Build strong local community 28 What is ONOS / CORD Ambassador Program Please feel free to ask. ONOS/CORD Ambassadors Team in Taiwan will be happy to discuss with you
