Network operators are eager to replicate the efficiencies that commodity cloud providers enjoy today. They want to achieve the economies of scale made possible through infrastructure constructed from a few commodity building blocks, as well as new levels of agility to be able to rapidly deploy and elastically scale services. The thousands of Central Offices (COs) they own and operate are well positioned to deliver innovative edge services, but are laboring under the opex/capex burden of closed/legacy hardware that's currently running in such facilities.
The Cord Project -- a newly announced Linux Foundation initiative to re-architect the Telco Central Office (or Cable Headend) as a Datacenter -- combines Software-Defined Networking (SDN), Network Functions Virtualization (NFV), and elastic cloud services to build cost-effective, agile access networks.

The inaugural CORD Summit, hosted by Google on July 29 in Sunnyvale, Calif., attracted more than 300 attendees, with technical sessions focused on the CORD architecture, as well as how to leverage CORD to deliver services to residential, mobile and enterprise customers. Keynotes from thought leaders at Google, AT&T, and China Unicom stressed the magnitude of the opportunity CORD provides. In addition to those three companies, current CORD partners include Ciena, Cisco, Fujitsu, Intel, NEC, Nokia, NTT, Radisys, Samsung, SK Telecom and Verizon.
An initial release of a reference implementation of CORD was announced at the Summit. It is a fully integrated system -- sufficiently complete to support field trials -- built from open source software, commodity servers and white box switches. Being an integrated system is an essential aspect of CORD, as the project's goal is go beyond a collection of loosely related projects listed under a common banner. Being "field-trial ready" is the target, with an initial residential (GPON-based) field trial under its belt, and additional residential and enterprise trials planned for the coming months.
With this objective in mind, much of the agenda focused on hammering out a roadmap for CORD going forward. The following are the highlights of that roadmap:
