The edge of the operator network (such as the central office for telcos and the head-end for cable operators) is where operators connect to their customers. CORD™ is a project intent on transforming this edge into an agile service delivery platform enabling the operator to deliver the best end-user experience along with innovative next-generation services.
The CORD (Central Office Re-architected as a Datacenter) platform leverages SDN, NFV and Cloud technologies to build agile datacenters for the network edge. Integrating multiple open source projects, CORD delivers a cloud-native, open, programmable, agile platform for network operators to create innovative services.
CORD provides a complete integrated platform, integrating everything needed to create a complete operational edge datacenter with built-in service capabilities, all built on commodity hardware using the latest in cloud-native design principles.
“70% of operators worldwide are planning to deploy CORD”
“Nearly 40% of all end-customers (residential, wireless and enterprice, collectively) will have service provided by COs or their equivalents using CORD by mid-2021”
CORD Hardware Architecture
- Commodity Servers Interconnected by a Fabric of White-box Switches
- Switching Fabric in a Spine-Leaf Topology for Optimized East-to-West Traffic
- Specialized access hardware for connecting subscribers (residential, mobile and/or enterprise)
Built with commodity hardware, the CORD platform leverages dozens of upstream open source projects including
Provides IaaS capability for creating and provisioning virtual machines (VMs) and virtual networks
Provides a container-based means to instantiate service elements
Network operating system that controls the underlying whitebox switching fabric and overlay networks, enabling delivery of end-user service from the fabric where possible (minimizing the need for all services to be hosted as VNFs on more expensive servers)
Framework for assembling and composing services
