CSPs are pushing for SD access network solutions, given the potential advantages, but they need solutions that accommodate legacy broadband equipment and services.
- The Broadband Forum’s (BBF's) CloudCO and OB-BAA initiatives have a large base of supporters and will likely be adopted by operators. The BBF has a proven track record with standardization efforts, such as NETCONF/YANG management for access networks.
- The ONF’s R-CORD and SEBA initiatives represent a big leap for the ecosystem, and while standardization efforts continue, it is struggling to attract wide-scale support across major access equipment vendors.
- Abstraction is the first step on the long road to open access networking and is fundamental for service automation and network function virtualization (NFV).
Features and Benefits
- This report assesses two major software-defined access network initiatives, their goals, and participants.
- This report discusses the implementation challenges of software-defined access network efforts along with the status of these efforts.
Key questions answered
- Why is it difficult to implement software-defined solutions into broadband access networks?
- What is the goal of the ONF's R-CORD and SEBA? What are the implementation challenges? Is there a viable ecosystem?
- What is the goal of the BBF's CloudCO and OB-BAA? What is the status of the efforts? Is there a viable ecosystem?
