The Central Office Re-architected as a Data Center (CORD) initiative, which was initially developed by ON.Lab as a use case for the ONOS open source SDN operating system, will now be managed as an independent open source project under The Linux Foundation. CORD aims to utilize merchant silicon and the elasticity of commodity clouds to enable data center economics and cloud agility in the central office environment.
Google, Radisys and Samsung Electronics Co. are joining CORD and ONOS Projects as new partners. Additional members of the CORD community include service provider partners AT&T, China Unicom, Google, NTT Communications, SK Telecom, and Verizon, vendors Ciena, Cisco, Fujitsu, Intel, NEC, Nokia, etc.
In addition, Google will host the first CORD Summit on July 29 at Google Sunnyvale Tech Corner Campus in California.
“We are delighted to welcome Google to the open source ONOS and CORD partnerships,” said Guru Parulkar, executive director at ON.Lab. “Given Google’s track record as a provider of cloud and access services, we anticipate it will play an important role in strengthening the CORD architecture, implementation, and deployments.”
“We are also delighted to partner with Radisys, a leading system integrator in the service provider space, and Samsung, which is committed to advancing next-generation mobile technologies. CORD is very well-positioned for future growth,” said Parulkar. “Radisys’ leadership for an open, vendor-agnostic solution for central office transformation will be critical in providing turn-key CORD Pods that will accelerate development and adoption of CORD, enabling ground-breaking network transformation. And Samsung as a leader in mobile networking will help ONOS and CORD in this impornat domain of use.”
“CORD has the potential to significantly improve the economics and agility of access networks globally,” said Ankur Jain, principal engineer at Google. “We are excited to join CORD, host its inaugural summit and work closely with leading ecosystem players to bring greater scalability and rapid innovation to access networks.”
CORD is expected to bring the economies of scale and the agility of cloud computing to the service provider central office by leveraging infrastructure constructed from commodity building blocks. It uses merchant silicon, white boxes and open-source platforms such as ONOS, OpenStack, and XOS.
CORD Use Cases Showcased at ONS:
Enterprise (E-CORD) - Extends CORD with enterprise services and enables service providers to offer SDN-WAN, as well as MEF carrier Ethernet services. That is the ability to create multi-site virtual networks on demand with customer-specified services such as intrusion detection, WAN acceleration, and others. E-CORD POC will be demonstrated at ONS.
Mobile (M-CORD) - Integrates disaggregated and virtualized RAN, disaggregated and virtualized EPC, and mobile edge computing with CORD and helps service providers and vendors move closer to realizing 5G. M-CORD POC will be demonstrated at ONS.
Residential (R-CORD) - Combines vCPE and virtualized wireline access technologies (e.g., GPON, 10GPON, G.Fast) with cloud-based subscriber services (e.g., parental control, video delivery). R-
Companies are actively contributing to and advancing CORD: AT&T, China Unicom, NTT Communications, SK Telecom, Verizon, Ciena, Cisco, Ericsson, Fujitsu, Huawei, Intel, NEC, Nokia

"AT&T supports the goals and achievements that are embodied in CORD," said Andre Fuetsch, senior vice president of Architecture and Design at AT&T. "The work is pushing the boundaries of many technologies and architectures, as well as open source and open spec hardware. We are learning from the CORD experiments and trials and using this knowledge to refine AT&T's Integrated Cloud. We look forward to continuing to collaborate with ON.Lab and others in advancing NFV and SDN technology."
