Title: CORD: Central Office Re-architected as a Datacenter


CORD (Central Office Re-architected as a Datacenter, combines NFV, SDN, and the elasticity of commodity clouds to bring datacenter economics and cloud agility to the Telco Central Office. CORD lets the operator manage their Central Offices using declarative modeling languages for agile, real-time configuration of new customer services. CORD leverages all OCP hardware and merchant silicon and white boxes for CO fabric, servers, and access; open source platforms such as OpenStack, Docker, ONOS, and XOS; and a set of open and closed services. Major service providers like AT&T, SK Telecom, Verizon, China Unicom and NTT Communications and a long list of vendors and systems integrators are already supporting CORD.

The CORD partnership has created and demonstrated three versions of CORD: (1) Residential-CORD for residential customers over GPON (2) Mobile-CORD for mobile customers with disaggregated and virtualized RAN and EPC and mobile edge computing; and (3) Enterprise-CORD to support enterprise customers with MEF and SD-WAN services including virtual network on demand. The CORD partnership plans to create and support open reference implementation of [R,E,M]CORD for the community to use and build on.

The talk will provide an overview of CORD, its progress so far and the future plans.
