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.
CORD is currently packaged into 3 solutions for different market use cases to support emerging edge applications like IoT, Gaming, VR, etc.
A distribution supporting 5G mobile edge services complete with disaggregated and virtualized radio (RAN) and an open source Mobile Core (EPC).
Supporting residential subscribers over wireline access technologies like GPON, G.Fast, 10GPON, and DOCSIS
Enterprise services such as virtual private networks (VPNs) and application optimization (SD-WAN) over metro and wide area networks
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
