Broadband Forum (BBF) and the Open Networking Foundation (ONF) announced a new agreement that determines how operators seeking to use virtualization and open source to increase agility can leverage open source and standardization projects side-by-side to ease their migrations to automated access networks and enable seamless co-existence.
BAA and SEBA/VOLTHA are complementary as they solve different carrier problems, while addressing operators’ increasing desire to move to agile, software-defined access networks via open source development with open and standardized interfaces. The agreement between Broadband Forum and ONF further builds on this by focusing on key aspects of migration and coexistence to interconnect existing parts of the access network with new technologies.
Broadband Forum and ONF believe that many types of carrier deployments would benefit from the capabilities offered by OB-BAA and SEBA/VOLTHA. The cooperation between the two organizations takes their work to the next level, providing an effective and efficient path for operators to leverage the innovations and benefits of both initiatives, while ensuring interoperability, high performance, scalability and maximum reliability.
As the broadband industry embarks on the next phase of broadband deployment, numerous new business opportunities are emerging that require rapid service instantiation, often across disparate, software-defined networks, and leveraging third-party applications. To take advantage of this untapped potential, operators are looking to interconnect different parts of their network with open source solutions and systems from various suppliers.
Open Broadband-Broadband Access Abstraction (OB-BAA) is a BBF open source project that enables SDN-based management and control of multi-vendor, multi-technology access networks via a standard abstraction northbound interface. It facilitates co-existence and seamless migration, bringing the agility to adapt to a variety of software defined access models.
The latest OB-BAA Release 2.0 – which is now ready for download – also expands the types of proprietary access nodes that can be managed and controlled via the BAA layer. This includes enabling additional adaptation of access nodes to meet individual network needs and providing examples of common functions that service providers are likely to perform when automating and managing their networks. These functionalities facilitate migration to cloud-based deployments for an increased number of service providers.
Release 2.1 of Open Broadband – Broadband Access Abstraction (OB-BAA) opens door for service provders to achieve simplified service provisioning and faster time-to-market.
This abstraction simplifies and reduces development upstream in management and control software for Physical and Virtual Network Functions (PNFs and VNFs). Inherent in the OB-BAA project is the ability to pull differing access device types, including legacy implementations, together under a single standardized network and service management & control umbrella to be exposed to management elements such as the SDN Management and Control and Element Management Systems.
ONF’s SDN Enabled Broadband Access (SEBA) platform takes a disaggregated white-box approach to building next generation access networks leveraging open source. Functionality traditionally run on chassis-based OLTs and on BNG routers, is run in the cloud, and the hardware is minimized to a collection of simple white-box OLTs, switches and servers.
SEBA wraps together this collection of open source hardware and software into a comprehensive platform that exposes northbound FCAPS interfaces, making it straight forward to integrate a SEBA POD with an operator’s OSS/BSS system.
ONF’s Virtual OLT Hardware Abstraction (VOLTHA) open source software project abstracts a PON network to make it manageable as if it were a standard OpenFlow switch. Functionality like DHCP and user authentication is run as open source in the cloud, giving operators control over functions that have traditionally been embedded in vendor tightly integrated chassis solutions. VOLTHA is used as a component of the SEBA platform and can also be used standalone by operators wanting to leverage just the specific capabilities of access network abstraction and SDN control.
