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.”

ETSI Open Source MANO LAUNCHES RELEASE TWELVE with enhanced network function resiliency and runtime operations

 

Sophia Antipolis, 30 June 2021:: ETSI OSM is pleased to announce OSM Release TWELVE, the second Long Term Support release of ETSI Open Source MANO and one of its most prolific releases. One of the main new features of Release TWELVE is the ability to heal network functions that may be affected by any kind of infrastructure failure. This healing process, which may be triggered either manually or automatically depending on operator preference, can be applied in all the clouds supported by OSM, in line with OSM’s multi-cloud approach.

In addition to significant improvements in day-2 operation of a network service, this release makes it possible to upgrade a running network function instance with a new package version, all with minimal downtime. Moreover, the composition of network services can also be modified in runtime.

To further increase interoperability with 3rd party solutions, ETSI OSM Release TWELVE supports additional ETSI NFV Specifications, such as ETSI GS NFV-SOL003 for VNF Lifecycle Management. With the support of the VNF Lifecycle Management APIs, Release TWELVE offers both the API of an NFV Orchestrator and the API of a Generic VNF Manager, providing operators with additional options for the integration of OSM in their Telco Cloud Architecture. This support of additional ETSI NFV specs continues the journey initiated since OSM creation, where ETSI GS NFV-SOL005 was already the foundation of OSM’s northbound interface, OSM data model and descriptors were derived from ETSI GS-NFV SOL 006, and its NF and NS package formats were also based on ETSI GS-NFV SOL 004 and ETSI GS-NFV SOL 007.

Finally, this new Release includes several interesting features for production deployment, such as the support of anti-affinity groups per VNF, the addition of password expiry policies, new options for Kubernetes cluster registration, and the experimental migration of Openstack-based network function instances.

OSM Release TWELVE is the second Long Term Support release (see OSM Release TEN declared LTS), and will provide two years of continuous support with bug fixes and security patches.

And the winner is…

This month was also the date of the remote OSM13 Hackfest featuring a Team Challenge aiming to on-board Magma 5G Core. The event was run as a team challenge with 6 teams collaborating through the week on the onboarding tasks and demonstrations. The best demo was awarded, briefings and videos are available here.

During the same week, the OSM#13 Ecosystem Day allowed organizations in the OSM Ecosystem to share their experience and how OSM is helping them to achieve their goals. Presentations and demos covered a wide range of aspects from research activities to production deployments, focusing on cutting-edge Telco use cases, such as Edge/MEC, 5G deployments and Wide Area Networks (WAN). See presentations here.
