WHAT IS OSM?

OSM is developing an open source Management and Orchestration (MANO) stack aligned with ETSI NFV Information Models. As a community-led project, OSM delivers a production-quality MANO stack that meets operators' requirements for commercial NFV deployments.

ETSI NFV Alignment

OSM is closely aligned with the evolution of ETSI NFV and provides a regularly updated reference implementation of NFV MANO.

Open Source

ETSI OSM uses well-established tools and methods to develop code under the Apache Public License 2.0.

Open Community

Participation to OSM is open to members and non-members of ETSI, as well as individual developers and end users from all across the globe. Check how to join or learn more about OSM.

WHAT PEOPLE ARE SAYING

“Operational effectiveness at the edge is critical to a successful 5G strategy and emerging business models for edge-based compute. OSM Release SIX connects edge and core to provide repeatable and reusable services that span the full telco topology and enable both 5G infrastructure and third-party app ecosystems for the edge in VMs and containers.”

Mark Shuttleworth

CEO of Canonical and founder of Ubuntu

“Management and Orchestration (MANO) is, at the same time, one of the key components and most controversial concepts in network virtualization architecture. Telefónica has long been working from the point of view of innovation in its development. A first result and seed of OSM is OpenMANO, a highly functional framework pioneering the first open source NFV Orchestration and Management stack and, currently, a key component of Telefónica’s NFV Reference Lab. By joining this community, we aim to accelerate the development of MANO while recognizing the value of open-source implementations of NFV and a need to harmonize efforts there.”

Antonio Elizondo

Head of Network Virtualisation Strategy and Technology, Global CTO Unit, Telefónica

“OSM has evolved from an interesting PoC into the most promising architecture for orchestrating VNFs, under the multi-vendor, standardized approach that our Telco customers have been looking for. Increased robustness, as well as exciting features that pave the path towards 5G and the Edge, let us build with confidence the second release of our distribution, WhiteNFV Barcelona, in order to cover the increased demand for operator-led, automated NFV deployments.”

Joris Vleminckx

COO Whitestack

“The ETSI OSG Open Source MANO (OSM) initiative will facilitate the development of open source software for management and orchestration of future networks. Knowledge, capabilities and solutions within this area will be of critical importance to Telenor when virtualizing the network for increased flexibility, faster service delivery, rapid innovation and operational efficiency.”

Patrick Waldemar

Vice President, Telenor Research

“Proprietary management and automation approaches have impeded NFV deployments. Service providers recognize the need for a standardized MANO information model delivered in conjunction with an open source MANO platform to cultivate a robust commercial NFV supplier ecosystem. I’m thrilled with the progress OSM has made to meet these needs and its growing industry acceptance.”

Matt Harper

OSM Founding Member, CTO, RIFT.io

OSM Governance

The OSM governance structure is made up of a Leadership Group, an End User Advisory Group, a Technical Steering Committee, Module Development Groups and various Task Forces.

Leadership Group (LG)

The role of the OSM Leadership Group is to set the policies of the project, to make administrative decisions and to guarantee vendor-neutrality. The members of the Leadership Group coordinate marketing efforts together with the Marketing Task Force and act as the main external representatives for OSM.


Francisco Javier Ramón - Chair

Francisco joined Telefónica Group in 2000 and became Head of IP Network Technologies R&D in 2008. In 2010, he was named Head of the Network Virtualisation Initiative in GCTO, in charge of developing network virtualisation use cases for Telefónica and responsible the unit released OpenMANO as the first open source MANO stack focused on resource orchestration. During the last 3 years he has chaired 2 different groups in ETSI NFV ISG and has been in charge of their experimental activities and PoC Framework. Francisco holds a Master in Telecommunications Engineering from ETSIT of Málaga (Spain) and a Master's Degree in Economics at UNED (Spain). Author of 8 patents and numerous papers in the fields of network virtualisation, traffic analysis, quality of experience, network Planning, and Internet of the Future, he’s also a member of the program committees of several national and international conferences.

Bruno Dzogovic - Vice-Chair
