R-CORD

• Residential CORD
• Design:
  • Virtual OLT (vOLT)
  • Virtual Subscriber Gateway (vSG)
  • Virtual Router (vRouter)

E-CORD

• Enterprise CORD
• OpenStack, Docker, ONOS, and XOS
• Open source
  • Openstack provides a base IaaS capability, and is responsible for creating and provisioning virtual machines (VMs) and virtual networks (VNs). CORD uses OpenStack’s Nova, Neutron, Keystone, Ceilometer and Glance subsystems.
  • ONOS is the network operating system that manages the white­box switches and software switches (OvS) in each server. It hosts control programs that implement services and it is responsible for embedding virtual networks in the underlying network.
  • XOS is a framework for assembling and composing services. It unifies data plane services supported by OpenStack and Docker, and the control plane services running on ONOS.
  • Atrium is the software stack that runs on each white­box switch. It includes Open Network Linux, the Indigo OpenFlow Agent (OF 1.3), and the OpenFlow Data Plane Abstraction (OF­DPA), layered on top of Broadcom merchant silicon. We also present a fully open sourced implementation of MEF Forum (MEF­ LSO Presto interface) services running on top of commodity hardware using open protocols (OpenFlow etc.).

M-CORD

• Mobile CORD

A-CORD

• Analytics for CORD

  

Trellis

• A unique combination of an underlay leaf-spine fabric, overlay virtual networking and unified SDN control over both underlay and overlay.

  

VOLTHA

• optical access system architecture, based on SDN/NFV technologies

XOS

• brings the Everything-as-a-Service (XaaS) organizing principle to the CORD architecture
• addresses several of CORD’s high-level design requirements, including a means to seamlessly integrate control plane (SDN) and data plane (NFV) based services
