Reference Designs

Reference Designs (RDs) represent a particular assembly of components that are required to build a deployable platform. They are “blueprints” developed by ONF’s Operator members to address specific use cases for the emerging edge cloud.

ONF’s operator leadership expanded ONF’s mission to create a new strategic plan to deploy open source solutions into their production networks. By committing to take open source solutions into production, ONF’s operator members are enabling a new supply chain ecosystem to help realize the full potential of SDN, disaggregation and open source.

RDs are the vehicles to describe how a collection of projects can be assembled into a platform to address specific needs of operators. By defining RDs, ONF’s operator members are showing the industry the path forward to solutions they plan to procure and deploy.

Each RD is backed by specific Operator partner(s) who plan to deploy these designs into their production networks and will include participation from invited supply chain partners sharing the vision and demonstrating active investment in building open source solutions. The RD thus enables a set of committed partners to work on the specification and a related open source platform.

Assembling the set of selected components defined by the RDs into a platform enables a proof-of-concept to allow the test and trial of the design. These platforms are called Exemplar Platforms and each of them will be based on a Reference Design and will serve as reference implementations. These platforms are designed to make it easy to download, modify, trial and deploy an operational instantiation and thereby speed up adoption and deployment.

Reference Designs & Exemplar Platforms

Listed below are the currently approved RDs and the Exemplar Platforms enabled by them.
Current multi-layer Networks

SDN Enabled Broadband Access (SEBA)

Lightweight platform based on a variant of R-CORD. Supports a multitude of virtualized access technologies at the edge of the carrier network, including PON, G.Fast, and eventually DOCSIS and more. Supports both residential access and wireless backhaul, and optimized such that traffic can run ‘fastpath’ straight through to the backbone without requiring VNF processing on a server.

Includes NEM - Network Edge Mediator, which leverages the XOS toolchain to provide mediation to different operators’ backend management/OSS systems and FCAPS support to operationalize the platform.

Trailblazing Activities

In addition to the Reference Designs and Exemplar Platforms that are all tightly scoped and on the verge of deployment, the ONF will continue to pursue open source platforms that lead next-generation activities for the industry.  These activities include:

M-CORD for next generation 5G mobile

Virtualized next-generation mobile core and RAN platform

CORD for the Multi-Access Edge Cloud

Brings together all the access technologies into a single edge cloud, and enables third-party edge applications to run on the carrier’s network.

CORD is the summation of the ONF’s edge cloud work, integrating all the related projects and bringing together all the access technologies into a single edge cloud.  Furthermore, CORD’s forward looking R&D is looking at enabling third-party edge applications to run on the carrier’s network, creating the infrastructure for an ‘app store’ for the carrier’s edge cloud.
