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 Presentation

Following Francisco-Javier, Andy Reid gave his perspective as the leader of the OSM End User Advisory Group. A key principle of OSM is that it is “operator led and requirements driven.” Andy drove home the key point that OSM’s goals are to deliver usable and industrial strength code for users and, equally important, give operators and developers the ability to learn by doing. He stressed that this is a whole new world for carriers and the value of open source is to foster an active development process and create a rapid feedback flow which will contribute to advances in architecture and standards. 

Adrian Hoban, the Chair of the Technical Steering Committee (TSC) of OSM built on Francisco-Javier’s session with a deep dive into the architectural principles of OSM and its scope and mapping to ETSI NFV. Adrian discussed OSM’s development themes which include easy onboarding & VNF packaging, simplified install and upgrade processes, improved development environment, service modeling, EPA, support for multiple VIMs and SDN controllers, and multi-site capability. Adrian provided some real depth that the audience appreciated. Attendees were very engaged and asked a lot of questions covering security, which SDN controllers are supported, the relationship between VNFM and NFVO and how OSM will evolve to commercial software. It was great to see so much interest from the audience, and it was very clear to me that OSM is addressing a gap in the market. Developers and operators are anxious for commercially viable MANO software.

During the afternoon, the workshop focused on OSM tutorials with Francisco-Javier walking through the download and installation process, followed by RIFT.io’s VP of Service Delivery, Noel Charath, demonstrating OSM Release ONE VNF Package creation, the GUI, and onboarding process. Lots of audience members were taking pictures as Noel demonstrated the Service Composer, and once again, the audience was very engaged and asked a lot of questions. 

The last technology session of the day featured Canonical’s CEO and member of OSM’s TSC, Mark Shuttleworth. Mark’s theme was cloud native data modeling and model driven operations. He stressed the importance of getting operators to cloud speed. He also won the award for memorable quote of the day: “The great thing about RIFT.io is it speaks telco, the great thing about Canonical (Juju charms) is it doesn’t.” The point being that the contributions of RIFT.io and Canonical are complementary and that OSM is bridging the worlds of telecommunications and cloud-native architecture and applications. 

Chris Buerger, the chairman of the OSM Marketing Task force finished the day pointing out that OSM is the fastest growing NFV open source project in the history of NFV open source projects. OSM is closing in on 50 corporate members. He had a simple message of, “Join us.”

Very often, trade shows are full of high-level marketing and product pitches. As the marketing lead at RIFT.io, I came away very impressed with the OSM workshop, which featured very rich content and provided real technology depth. If you missed it, slides and video recordings are available at  www.layer123.com/sdn-webcast. It was a great way to start the conference and served as a foundation for a lot of conversations on the expo floor and at cocktail hours and dinners. Nearly every conversation we had in the RIFT.io booth with carriers, VNF builders, and press and analysts featured OSM discussion and lots of questions about Release ONE and the roadmap. OSM’s momentum is undeniable and I’ll echo Chris’s message: Join us!
