ATLANTA and MENLO PARK, Calif., March 22, 2018 /PRNewswire/ -- Today
AT&T and the Open Networking Foundation (ONF) are announcing a
collaboration to integrate the ONFs' work on multi-gigabit passive
optic networks (PON) with the service automation system, ONAP. Work
will begin to integrate VOLTHA (Virtual Optical Line Termination
Hardware Abstraction), the open source software stack powering PON
networks, with ONAP.
This is the next step for agile development progression for
virtualized and disaggregated network access for PON
networks.
This will build upon ongoing field trials of XGS-PON, which is a
fixed wavelength symmetrical 10Gbps passive optic network
technology. It also builds upon previous GPON and CORD trials.
These trials proved the viability of disaggregated architecture and
the effectiveness of open source and open specs in transforming
networking.
The current XGS-PON trial is testing multi-gigabit high-speed
internet traffic and providing a AT&T DIRECTV NOW video
experience to trial participants. To build the network, we used the
following open source software.
- AT&T Open XGS-PON OLT: an OCP Accepted white box OLT
- ONOS: the ONF SDN controller that hosts virtual OLT control
applications
- vBNG: a virtual broadband network gateway application to manage
subscribers
- VOLTHA (Virtual Optical Line Termination Hardware Abstraction):
an ONF software project that provides hardware abstraction and a
highly available SDN driver for OLT devices.
VOLTHA, the software powering the PON network trials, was
developed by an ONF project community and used the latest in DevOps
development techniques to enable rapid prototyping and accelerated
delivery to the field trial. AT&T's Foundry in Atlanta developed the vBNG software and
AT&T provided overall system integration and field operations
for the trial.
"Our network is constantly evolving. Collaboration and openness
across AT&T, the ONF, and VOLTHA teams will be key to bringing
this 10 Gbps broadband network to customers faster," said
Igal Elbaz, senior vice president,
Wireless Network Architecture and Design, AT&T. "Now that we've
proven the viability of open access technology in our trials, we
can start the integration with our operations and management
automation platform – ONAP."
"This is representative of how open source communities can come
together to introduce solutions that address more comprehensively
operator needs," said Jim Zemlin,
Executive Director, The Linux Foundation.
"AT&T's Access team has been an important collaborator in
ONF's mission to provide open source platforms for software defined
broadband access and we look forward to building on this
collaboration as we integrate with ONAP," said Guru Parulkar,
Executive Director, ONF.
About the ONF:
The Open Networking Foundation (ONF) is an operator led
consortium spearheading disruptive network transformation. Now the
recognized leader for open source solutions for operators, the ONF
first launched in 2011 as the standard bearer for Software Defined
Networking (SDN). Led by its operator partners AT&T, China
Unicom, Comcast, Deutsche Telekom, Google, NTT Group and Turk
Telekom, the ONF has now merged operations with ON.Lab to create a
single organization driving vast transformation across the operator
space. For further information visit
