Multi-Access CORD and Extensible RAN Use Cases Featured in ONF Partner Showcase

HILLSBORO, OR, U.S. – September 11, 2017Radisys® Corporation (NASDAQ: RSYS), a global leader of open telecom solutions, today announced an industry first Multi-Access Central Office Re-architected as a Datacenter (Multi-Access CORD) proof-of-concept and an Extensible RAN (xRAN) PoC to be showcased at MWC Americas. The two new use cases, both running on Radisys’ DCEngine open hardware, enable Communications Service Providers (CSPs) to optimize resources in a CORD™ environment, allowing for rapid roll-out of new services with a better return on investment.


  • CSPs are rethinking their network access design in order to support billions of connected devices and meet the demands of new innovative services. The CORD platform is an open architecture that brings data center economies and cloud agility to the network for the delivery of mobile, residential and enterprise services.
  • To date, CSPs have been constrained by data centers for either wireline (OLT) or wireless (RAN) access. This results in duplicate central offices laden with proprietary infrastructure and redundant systems to deliver each service, resulting in higher CapEx and OpEx costs.
  • Radisys’ Multi-Access CORD use case demonstration proves that since the flexible CORD architecture is agnostic to the access technologies, CSPs can leverage the same CORD data center for both wireline and wireless access. CSPs can thereby deliver a higher quality experience to their subscribers with one open architecture, while reducing network complexity and costs.
  • Radisys’ xRAN use case demonstration allows CSPs to optimize scarce over-the-air resources leveraging real-time data analytics of network conditions. This software-based approach to RAN reduces complexity, OpEx and CapEx, while allowing CSPs to respond real-time to user needs and rapidly roll-out new services.
  • Both proof-of-concepts are running on Radisys’ open compute-based DCEngine, which provides an economical, scalable open platform for pooled compute and storage resources in a CORD environment.
    • Radisys will be showcase the Multi-Access CORD and xRAN proof-of-concepts in the ONF Partner Showcase, N.322 at Mobile World Congress Americas, September 12-14 in San Francisco. Contact open@radisys.com to schedule a meeting with Radisys’ CORD experts.

“The CORD reference architecture meets CSP requirements for next-gen service delivery, while at the same time freeing them from vendor-locked solutions,” said Bryan Sadowski, vice president, FlowEngine and DCEngine, Radisys. “Radisys, in collaboration with the ONF, is making the CORD architecture accessible to CSPs for deployment with these innovative proof-of-concepts as the first step toward Central Office transformation.”

“From the beginning, one of the main goals of the CORD project has always been to create a general-purpose platform capable of delivering a wide range of innovative services for mobile, residential and enterprise subscribers,” said Guru Parulkar, executive director, Open Networking Foundation (ONF). “Radisys’ delivery of a Multi-Access CORD solution furthers our mission by providing CSPs with one solution that will support multiple classes of subscribers. We are pleased to partner with Radisys and feature this innovative solution in our Partner Showcase at MWC Americas.”
